我想创建一个自定义对话框如下

我尝试了以下几点。

我创建了AlertDialog的子类。生成器,并使用自定义标题和自定义内容视图,并使用,但结果不是预期的。 另一个尝试是子类DialogFragment和自定义对话框内的onCreateDialog,但结果不是预期的。 然后我尝试使用一个普通的Dialog类。结果并不如预期的那样。

在这三种情况下,问题是当我忽略标题视图时,对话框的大小不是预期的,当我使用标题视图时,结果是在内容视图周围有一个粗边框(这看起来真的很糟糕)。现在我脑子里有两个问题……

我怎样才能做到呢?因为我已经尝试了很多事情,直接的回答会更受欢迎。 在android应用程序中显示错误或警告对话框的最佳方式是什么?

编辑 Android开发者文档建议我们应该使用对话片段或对话框向用户显示错误/警报消息。然而,他们一度说……

提示:如果你想要一个自定义对话框,你可以将一个Activity显示为一个对话框,而不是使用对话框api。简单地创建一个活动,并将其主题设置为manifest元素中的theme . holo . dialog。

这是什么意思?仅仅是为了显示错误消息而使用Activity不是太过分了吗??


在values -> style.xml中添加以下主题

<style name="Theme_Dialog" parent="android:Theme.Light">
     <item name="android:windowNoTitle">true</item>
     <item name="android:windowBackground">@android:color/transparent</item>
</style>

在onCreateDialog方法中使用这个主题,如下所示:

Dialog dialog = new Dialog(FlightBookActivity.this,R.style.Theme_Dialog);

在xml文件中定义你的对话框布局,包括标题栏,并像这样设置xml文件:

dialog.setContentView(R.layout.your_dialog_layout);

这里我创建了一个简单的对话框,像这样:

custom_dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold"/>
    

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

你必须扩展对话框和实现OnClickListener

public class CustomDialogClass extends Dialog implements
    android.view.View.OnClickListener {

  public Activity c;
  public Dialog d;
  public Button yes, no;

  public CustomDialogClass(Activity a) {
    super(a);
    // TODO Auto-generated constructor stub
    this.c = a;
  }

  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    setContentView(R.layout.custom_dialog);
    yes = (Button) findViewById(R.id.btn_yes);
    no = (Button) findViewById(R.id.btn_no);
    yes.setOnClickListener(this);
    no.setOnClickListener(this);

  }

  @Override
  public void onClick(View v) {
    switch (v.getId()) {
    case R.id.btn_yes:
      c.finish();
      break;
    case R.id.btn_no:
      dismiss();
      break;
    default:
      break;
    }
    dismiss();
  }
}

如何呼叫对话?

R.id.TXT_Exit:
CustomDialogClass cdd=new CustomDialogClass(Values.this);
cdd.show();  

更新

过了很长一段时间,我的一个朋友让我做一个带有透明背景的曲线形状对话框。这里我实现了它。

要制作一个弯曲的形状,你需要创建一个单独的curve_shape . xml,如下所示,

<shape xmlns:android="http://schemas.android.com/apk/res/android" >

    <solid android:color="#000000" />

    <stroke
        android:width="2dp"
        android:color="#ffffff" />

    <corners
        android:bottomLeftRadius="20dp"
        android:bottomRightRadius="20dp"
        android:topLeftRadius="20dp"
        android:topRightRadius="20dp" />

</shape>

现在,在你的主视图布局中添加这个curve_shap.XML。在我的情况下,我已经使用线性布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="80dp"
        android:background="@drawable/curve_shap"
        android:orientation="vertical" >
...
</LinearLayout>

这怎么叫?

CustomDialogClass cdd = new CustomDialogClass(MainActivity.this);
cdd.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
cdd.show();

我希望这对你有用。


另一种简单的方法。

步骤1)创建一个布局与适当的id。

步骤2)在任何你想要的地方使用以下代码。

LayoutInflater factory = LayoutInflater.from(this);
final View deleteDialogView = factory.inflate(R.layout.mylayout, null);
final AlertDialog deleteDialog = new AlertDialog.Builder(this).create();
deleteDialog.setView(deleteDialogView);
deleteDialogView.findViewById(R.id.yes).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        //your business logic 
        deleteDialog.dismiss();
    }
});
deleteDialogView.findViewById(R.id.no).setOnClickListener(new OnClickListener() {    
    @Override
    public void onClick(View v) {
        deleteDialog.dismiss();    
    }
});

deleteDialog.show();

public static void showCustomAlertDialog(Context context, String name,
            String id, String desc, String fromDate, String toDate,
            String resions) {
        final AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(
                context);
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View view = inflater.inflate(R.layout.dialog, null);
        alertDialogBuilder.setView(view);
        alertDialogBuilder.setCancelable(false);
        final AlertDialog dialog = alertDialogBuilder.create();
        dialog.show();
        txt_empId = (TextView) view.findViewById(R.id.txt_dialog_empcode);
        txt_empName = (TextView) view.findViewById(R.id.txt_dialog_empname);
        txt_desc = (TextView) view.findViewById(R.id.txt_dialog_desc);
        txt_startDate = (TextView) view.findViewById(R.id.txt_dialog_startDate);
        txt_resions = (TextView) view.findViewById(R.id.txt_dialog_endDate);
        txt_empId.setTypeface(Utils.setLightTypeface(context));
        txt_empName.setTypeface(Utils.setLightTypeface(context));
        txt_desc.setTypeface(Utils.setLightTypeface(context));
        txt_startDate.setTypeface(Utils.setLightTypeface(context));
        txt_resions.setTypeface(Utils.setLightTypeface(context));

        txt_empId.setText(id);
        txt_empName.setText(name);

        txt_desc.setText(desc);
        txt_startDate.setText(fromDate + "\t to \t" + toDate);
        txt_resions.setText(resions);



        btn_accept = (Button) view.findViewById(R.id.btn_dialog_accept);
        btn_reject = (Button) view.findViewById(R.id.btn_dialog_reject);
        btn_cancel = (Button) view.findViewById(R.id.btn_dialog_cancel);
        btn_accept.setTypeface(Utils.setBoldTypeface(context));
        btn_reject.setTypeface(Utils.setBoldTypeface(context));
        btn_cancel.setTypeface(Utils.setBoldTypeface(context));

        btn_cancel.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                dialog.dismiss();

            }
        });

    }

这是一个示例对话框,使用xml创建。

下面的代码XML只是一个例子,设计或视图在这里实现:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#ffffffff">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="120dp"
    android:id="@+id/a"
    android:gravity="center"
    android:background="#DA5F6A"
    android:src="@drawable/dialog_cross"
    android:scaleType="fitCenter" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="TEXTO"
    android:id="@+id/text_dialog"
    android:layout_below="@+id/a"
    android:layout_marginTop="20dp"
    android:layout_marginLeft="4dp"
    android:layout_marginRight="4dp"
    android:layout_marginBottom="20dp"
    android:textSize="18sp"
    android:textColor="#ff000000"
    android:layout_centerHorizontal="true"
    android:gravity="center_horizontal" />

<Button
    android:layout_width="wrap_content"
    android:layout_height="30dp"
    android:text="OK"
    android:id="@+id/btn_dialog"
    android:gravity="center_vertical|center_horizontal"
    android:layout_below="@+id/text_dialog"
    android:layout_marginBottom="20dp"
    android:background="@drawable/btn_flat_red_selector"
    android:layout_centerHorizontal="true"
    android:textColor="#ffffffff" />

</RelativeLayout>

这行代码是drawable的资源:

android:src="@drawable/dialog_cross"
android:background="@drawable/btn_flat_red_selector"

你可以做一个类扩展对话框,也像这样:

public class ViewDialog {

    public void showDialog(Activity activity, String msg){
        final Dialog dialog = new Dialog(activity);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setCancelable(false);
        dialog.setContentView(R.layout.dialog);

        TextView text = (TextView) dialog.findViewById(R.id.text_dialog);
        text.setText(msg);

        Button dialogButton = (Button) dialog.findViewById(R.id.btn_dialog);
        dialogButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                dialog.dismiss();
            }
        });

        dialog.show();

    }
}

最后是call的形式,以你的活动为例:

ViewDialog alert = new ViewDialog();
alert.showDialog(getActivity(), "Error de conexión al servidor");

我希望它对你有用。

更新

可绘制的XML对话框:

<shape xmlns:android="schemas.android.com/apk/res/android"> <stroke android:width="2dp" android:color="#FFFFFF" /> <gradient android:angle="180" android:endColor="@color/NaranjaOTTAA" android:startColor="@color/FondoActionBar" /> <corners android:bottomLeftRadius="7dp" android:bottomRightRadius="7dp" android:topLeftRadius="7dp" android:topRightRadius="7dp" /> </shape> 

此xml由@GastónSaillén提供。


更改背景颜色和文本样式的最简单方法是为android警报对话框自定义主题,如下所示

:只需将下面的代码放入styles.xml:

    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
    <item name="android:textColor">#999999</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:typeface">monospace</item>
    <item name="android:backgroundDimEnabled">false</item>
    <item name="android:textSize">@dimen/abc_text_size_medium_material</item>
    <item name="android:background">#80ff00ff</item>
</style>

:现在自定义的事情已经完成,现在只应用到你的alertBuilder对象:

    AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this,R.style.AlertDialogCustom);

希望这对你有帮助!


你可以尝试这个简单的android对话框弹出库来减少混乱的对话框代码。在您的活动中使用它非常简单。 在此之后,您可以在活动中使用此代码来显示对话框

Pop.on(this).with().title(R.string.title).layout(R.layout.custom_pop).show();

出来的地方。Custom_pop是你想要装饰对话框的自定义布局。


创建自定义警报布局custom_aler_update.xml

然后将此代码复制到Activity:

AlertDialog basic_reg;
AlertDialog.Builder builder ;
builder = new AlertDialog.Builder(ct, R.style.AppCompatAlertDialogStyle);
LayoutInflater inflater = ((Activity) ct).getLayoutInflater();
View v = inflater.inflate(R.layout.custom_aler_update, null);
builder.setView(v);
builder.setCancelable(false);
builder.create();
basic_reg = builder.show();

复制此代码到样式:

<style name="AppCompatAlertDialogStyle" parent="Theme.AppCompat.Light.Dialog.Alert">
    <item name="colorAccent">@color/colorAccent</item>
    <item name="android:textColorPrimary">@color/primaryTextColor</item>
    <item name="android:background">@color/white</item>
</style>

简单先创建一个类

 public class ViewDialog {

        public void showDialog(Activity activity, String msg){
            final Dialog dialog = new Dialog(activity);
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
            dialog.setCancelable(false);
            dialog.setContentView(R.layout.custom_dialogbox_otp);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

            TextView text = (TextView) dialog.findViewById(R.id.txt_file_path);
            text.setText(msg);

            Button dialogBtn_cancel = (Button) dialog.findViewById(R.id.btn_cancel);
            dialogBtn_cancel.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Cancel" ,Toast.LENGTH_SHORT).show();
                    dialog.dismiss();
                }
            });

            Button dialogBtn_okay = (Button) dialog.findViewById(R.id.btn_okay);
            dialogBtn_okay.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
//                    Toast.makeText(getApplicationContext(),"Okay" ,Toast.LENGTH_SHORT).show();
                    dialog.cancel();
                }
            });

            dialog.show();
        }
    }

然后创建custom_dialogbox_otp

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="330dp"
    android:layout_height="160dp"

                        android:textColor="#ffffffff" />

                </LinearLayout>
            </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

然后在XML文件下面的可绘制的创建中。 对于round_layout_white_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="36dp" />
    <solid android:color="#C0C0C0" />
    </shape>

对于round_layout_otp.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="18dp"
        android:bottomRightRadius="16dp"
        android:topLeftRadius="38dp"
        android:topRightRadius="38dp" />
    <solid android:color="#DA5F6A" />
    </shape>

round_button

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <!-- <corners android:radius="10dp" /> -->
    <corners
        android:bottomLeftRadius="7dp"
        android:bottomRightRadius="7dp"
        android:topLeftRadius="7dp"
        android:topRightRadius="7dp" />
    <solid android:color="#06A19E" />
    </shape>

然后最后使用下面的代码来可视化你的对话框:)

ViewDialog alert = new ViewDialog();
        alert.showDialog(ReceivingOTPRegActivity.this, "OTP has been sent to your Mail ");

你的输出:)

答案更新:用于kotlin

  class ViewDialog {
        fun showResetPasswordDialog(activity: Activity?) {
            val dialog = Dialog(activity!!)
            dialog.requestWindowFeature(Window.FEATURE_NO_TITLE)
            dialog.setCancelable(false)
            dialog.setContentView(R.layout.resetpass_popup)
            dialog.window!!.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
            val dialogBtn_remove = dialog.findViewById<TextView>(R.id.txtClose)
            dialogBtn_remove.setOnClickListener {
                dialog.dismiss()
                activity!!.finish()
            }
            dialog.show()
        }
    }

你的xml设计,

现在,你可以打电话了

val alert = ViewDialog()
alert.showResetPasswordDialog(activity)

你的结果,


对话片段是创建自定义警报对话框的最简单方法。按照上面的代码为你的对话框创建一个自定义视图,然后使用对话框片段实现它。在布局文件中添加以下代码:

 <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="80dp"
    android:background="#3E80B4"
    android:orientation="vertical">

    <TextView
        android:id="@+id/txt_dia"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:layout_margin="10dp"
        android:text="Do you realy want to exit ?"
        android:textColor="@android:color/white"
        android:textSize="15dp"
        android:textStyle="bold" />


    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        android:background="#3E80B4"
        android:orientation="horizontal">

        <Button
            android:id="@+id/btn_yes"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="Yes"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />

        <Button
            android:id="@+id/btn_no"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_marginLeft="5dp"
            android:background="@android:color/white"
            android:clickable="true"
            android:text="No"
            android:textColor="#5DBCD2"
            android:textStyle="bold" />
    </LinearLayout>

</LinearLayout>

创建自定义对话框的最简单方法:

Initialize and show dialog: ViewDialog alertDialoge = new ViewDialog(); alertDialoge.showDialog(getActivity(), "PUT DIALOG TITLE"); Create method: public class ViewDialog { public void showDialog(Activity activity, String msg) { final Dialog dialog = new Dialog(activity); dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); dialog.setCancelable(false); dialog.setContentView(R.layout.custom_dialoge_feedback); TextView text = (TextView) dialog.findViewById(R.id.text_dialog_feedback); text.setText(msg); Button okButton = (Button) dialog.findViewById(R.id.btn_dialog_feedback); Button cancleButton = (Button) dialog.findViewById(R.id.btn_dialog_cancle_feedback); final EditText edittext_tv = (EditText) dialog.findViewById(R.id.dialoge_alert_text_feedback); okButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { //Perfome Action } }); cancleButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View view) { dialog.dismiss(); } }); dialog.show(); } } Create layout XML which you want or need.


创建这样的警告对话框布局

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" 
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <Button
        android:id="@+id/btn"
        android:layout_width="match_parent"
        android:text="Custom Alert Dialog"
        android:layout_height="40dp">
    </Button>
</LinearLayout>

在Activity类上添加下面的代码

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    LayoutInflater inflate = LayoutInflater.from(this);
    alertView = inflate.inflate(R.layout.your_alert_layout, null);
    Button btn= (Button) alertView.findViewById(R.id.btn);

    showDialog();
  }

 public void showDialog(){
        Dialog alertDialog = new Dialog(RecognizeConceptsActivity.this);
        alertDialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        alertDialog.setContentView(alertView);
        alertDialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
        alertDialog.show();
    }

它是Alert Dialog的类,所以你可以从任何活动调用该类来重用代码。

public class MessageOkFragmentDialog extends DialogFragment {
Typeface Lato;
String message = " ";
String title = " ";
int messageID = 0;

public MessageOkFragmentDialog(String message, String title) {
    this.message = message;
    this.title = title;
}


@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());

    LayoutInflater inflater = getActivity().getLayoutInflater();

    View convertview = inflater.inflate(R.layout.dialog_message_ok_box, null);


    Constants.overrideFonts(getActivity(), convertview);
    Lato = Typeface
            .createFromAsset(getActivity().getAssets(), "font/Lato-Regular.ttf");


    TextView textmessage = (TextView) convertview
            .findViewById(R.id.textView_dialog);

    TextView textview_dialog_title = (TextView) convertview.findViewById(R.id.textview_dialog_title);

    textmessage.setTypeface(Lato);
    textview_dialog_title.setTypeface(Lato);



    textmessage.setText(message);
    textview_dialog_title.setText(title);



    Button button_ok = (Button) convertview
            .findViewById(R.id.button_dialog);
    button_ok.setTypeface(Lato);

    builder.setView(convertview);
    button_ok.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {
            dismiss();

        }
    });


    return builder.create();

}
}

相同的Xml文件是:

    <?xml version="1.0" encoding="utf-8"?>

    android:layout_width="fill_parent"

                android:textSize="@dimen/txtSize_Medium" />


        </LinearLayout>

我发现这是显示自定义对话框的最简单方法。

你有布局your_layout。xml

public void showCustomDialog(final Context context) {
    Dialog dialog = new Dialog(context);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    view = inflater.inflate(R.layout.your_layout, null, false);
    findByIds(view);  /*HERE YOU CAN FIND YOU IDS AND SET TEXTS OR BUTTONS*/
    ((Activity) context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE | WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);
    dialog.setContentView(view);
    final Window window = dialog.getWindow();
    window.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    window.setBackgroundDrawableResource(R.color.colorTransparent);
    window.setGravity(Gravity.CENTER);
    dialog.show();
}

我正在发布我正在使用的kotlin代码,它对我来说很好。您还可以为对话框按钮设置单击侦听器。

这是我的XML代码:

            listener.onClick(btn_positive)
            dialog.dismiss()
        }
    }

    fun setNegativeClickListener(listener: onClickListener)
    {
        btn_negative.setOnClickListener { v ->
            listener.onClick(btn_negative)
            dialog.dismiss()
        }
    }

    fun setPoitiveButtonText(text : String)
    {
        btn_positive.text = text
    }


    fun setNegativeButtonText(text : String)
    {
        btn_negative.text = text
    }

    fun setAlertTitle(title : String)
    {
        txt_alert_title.text = title
    }
}

用于点击监听器的接口:

onClickListener.kt

interface onClickListener{
    fun onClick(view : View)
}

示例使用

val dialog = mAlertDialog(context)
                dialog.setNegativeButtonText("no i dont")
                dialog.setPoitiveButtonText("yes is do")
                dialog.setAlertTitle("do you like this alert dialog?")

                dialog.setPositiveClickListener(object : onClickListener {
                    override fun onClick(view: View) {
                        Toast.makeText(context, "yes", Toast.LENGTH_SHORT).show()
                    }
                })

                dialog.setNegativeClickListener(object : onClickListener {
                    override fun onClick(view: View) {
                        Toast.makeText(context, "no", Toast.LENGTH_SHORT).show()
                    }
                })

                dialog.show()

我希望,这将帮助你!


创建自定义警报对话框

cumstomDialog.xml

<ImageView
    android:id="@+id/icon"
    android:layout_width="50dp"
    android:layout_height="50dp"
    android:layout_gravity="center"
    android:layout_margin="5dp"
    app:srcCompat="@drawable/error" />

<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:fontFamily="@font/muli_bold"
    android:text="Title"
    android:layout_marginTop="5dp"
    android:textColor="@android:color/black"
    android:textSize="15sp" />


<TextView
    android:id="@+id/description"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:layout_marginTop="10dp"
    android:fontFamily="@font/muli_regular"
    android:text="Message"
    android:textColor="@android:color/black"
    android:textSize="12dp" />

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center_horizontal"
    android:layout_marginTop="20dp"
    android:gravity="center"
    android:orientation="horizontal">

    <Button
        android:id="@+id/cancelBTN"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:layout_margin="5dp"
        android:background="@drawable/bground_radius_button_white"
        android:text="No"
        android:textColor="@color/black" />

    <Button
        android:id="@+id/acceptBtn"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_margin="5dp"
        android:background="@drawable/bground_radius_button"
        android:text="Yes"
        android:textColor="@color/white" />
</LinearLayout>

在你的活动上显示你的自定义对话框:

  public void showDialog(String title, String des, int icon) {

    final Dialog dialog = new Dialog(this);
    dialog.setContentView(R.layout.custom_dialog);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    Button cancelBTN = dialog.findViewById(R.id.cancelBTN);
    Button acceptBTN = dialog.findViewById(R.id.acceptBtn);
    TextView tvTitle = dialog.findViewById(R.id.title);
    TextView tvDescription = dialog.findViewById(R.id.description);
    ImageView ivIcon = dialog.findViewById(R.id.icon);

    tvTitle.setText(title);
    tvDescription.setText(des);
    ivIcon.setImageResource(icon);

    cancelBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });

    acceptBTN.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

        }
    });

    dialog.show();
}

像这样调用:

“标题”、“信息”、“警告”;


导入自定义警报:

LayoutInflater inflater = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
View view = inflater.inflate(R.layout.dse_location_list_filter, null);
final Dialog dialog = new Dialog(Acitvity_name.this);
dialog.setContentView(view);
dialog.setCancelable(true);
dialog.setCanceledOnTouchOutside(true);
dialog.show();

全屏自定义警报对话框类在Kotlin

Create XML file, same as you would an activity Create AlertDialog custom class class Your_Class(context:Context) : AlertDialog(context){ init { requestWindowFeature(Window.FEATURE_NO_TITLE) setCancelable(false) } override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContentView(R.layout.your_Layout) val window = this.window window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.MATCH_PARENT) //continue custom code here //call dismiss() to close } } Call the dialog within the activity val dialog = Your_Class(this) //can set some dialog options here dialog.show()

注意**:如果您不希望对话框全屏显示,请删除以下行

      val window = this.window
      window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                         WindowManager.LayoutParams.MATCH_PARENT)

然后在XML文件中编辑顶部布局的layout_width和layout_height,使其为wrap_content或固定的DP值。

我通常不建议使用固定的DP,因为你可能希望你的应用能适应多种屏幕尺寸,但如果你保持你的尺寸值足够小,你应该没问题


下面是用kotlin创建自定义视图对话框的代码。 下面是对话框布局文件

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical" android:layout_width="300dp"
    android:layout_height="400dp">

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />


</androidx.constraintlayout.widget.ConstraintLayout>

在文本视图中创建对话框并更新文本

val dialog = Dialog(activity!!)
dialog.setContentView(R.layout.my_dialog_layout)
dialog.tvTitle.text = "Hello World!!"
dialog.show()

下面是一个创建自定义对话框的简单方法。

dialog.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical">
<!--  Put your layout content  -->
</LinearLayout>

MainActivity.java

ShowPopup(){
LayoutInflater li = LayoutInflater.from(this);
View promptsView = li.inflate(R.layout.dialog, null);
android.app.AlertDialog.Builder alertDialogBuilder = new 
android.app.AlertDialog.Builder(this);
alertDialogBuilder.setView(promptsView);
alertDialogBuilder.setCancelable(true);
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
}

用这段代码正确显示自定义对话框的简单方法

dialog_choose_photo.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

    android:layout_marginBottom="@dimen/_5sdp"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/bg_dialog_smallround_white"
        android:orientation="vertical">

        <TextView

            android:textColor="#3080C7"
            android:textSize="18sp" />

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="#F1F0F0" />

        <TextView
            android:id="@+id/txt_gallery"

        android:background="@drawable/bg_dialog_smallround_white"
        android:orientation="vertical">

        <TextView
            android:id="@+id/txt_cancel_dialog"

            android:textColor="@color/colorPrimary"
            android:textSize="18sp" />
    </LinearLayout>


</LinearLayout>


</RelativeLayout>

只要调用这个函数

 public void openPhotoDialog() {
    final Dialog dialog = new Dialog(this);
    dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
    dialog.setContentView(R.layout.dialog_choose_photo);
    dialog.setCancelable(true);

    // Setting dialogview

    final Window window = dialog.getWindow();
    window.setLayout(AbsListView.LayoutParams.MATCH_PARENT, AbsListView.LayoutParams.WRAP_CONTENT);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    WindowManager.LayoutParams wlp = window.getAttributes();

    wlp.gravity = Gravity.BOTTOM;
    window.addFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
    window.setDimAmount(0.5f);
    window.setAttributes(wlp);


    TextView txt_camera = dialog.findViewById(R.id.txt_camera);
    TextView txt_gallery = dialog.findViewById(R.id.txt_gallery);
    TextView txt_cancel_dialog = dialog.findViewById(R.id.txt_cancel_dialog);

    txt_camera.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });
    txt_gallery.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });
    txt_cancel_dialog.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            dialog.getWindow().clearFlags(WindowManager.LayoutParams.FLAG_DIM_BEHIND);
            dialog.dismiss();
        }
    });

    dialog.show();

}
