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>

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。

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:padding="7dp"
        android:weightSum="100">

        <LinearLayout

                android:layout_weight="80"
                android:gravity="center">

                <ImageView

                    android:background="#DA5F6A"
                    android:gravity="center"
                    android:scaleType="fitCenter"
                    android:src="@mipmap/infoonetwo" />

            </LinearLayout>

            <LinearLayout
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                    android:layout_height="wrap_content"
                    android:layout_gravity="center"

                    android:textSize="17sp"

            </LinearLayout>

                android:layout_weight="60">

                    android:layout_weight="50"
                    android:gravity="center|right">

                    <Button

                    android:layout_marginLeft="30dp"
                    android:layout_weight="50"
                    android:gravity="center|left">


                    <Button

                        android:layout_width="80dp"
                        android:layout_height="25dp"
                        android:background="@drawable/round_button"
                        android:text="OKAY"
                        android:textSize="13dp"
                        android:textStyle="bold"
                        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，

                android:text="Close"
                android:textColor="@color/white_o"
                android:textSize="16dp"
                tools:ignore="HardcodedText,RtlHardcoded,SpUsage"></TextView>

        </LinearLayout>

    </androidx.cardview.widget.CardView>
</androidx.constraintlayout.widget.ConstraintLayout>

现在，你可以打电话了

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

你的结果，

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:

mAlertDialog.kt

class mAlertDialog(context: Context) {

    private val btn_positive : Button
    private val btn_negative : Button
    private val txt_alert_title : TextView
    private val dialog : AlertDialog
    init {
        val view = LayoutInflater.from(context).inflate(R.layout.layout_custom_alert_dialog,null)

        val dialog_builder = AlertDialog.Builder(context)
        dialog_builder.setView(view)

        btn_negative = view.findViewById(R.id.btn_alert_negative)
        btn_positive = view.findViewById(R.id.btn_alert_positive)
        txt_alert_title = view.findViewById(R.id.txt_alert_title)

        dialog = dialog_builder.create() 
    }

    fun show()
    {
        dialog.show()
    }

    fun setPositiveClickListener(listener :onClickListener)
    {
        btn_positive.setOnClickListener { v ->
            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!

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);
