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。

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

        <LinearLayout
            android:layout_width="match_parent"

            android:orientation="horizontal"

            </LinearLayout>

                    android:textSize="17sp"
                    android:textStyle="bold" />
            </LinearLayout>
        </LinearLayout>

        <LinearLayout

                    android:layout_height="match_parent"
                    android:layout_marginRight="30dp"
                    android:layout_weight="50"
                    android:gravity="center|right">

                    <Button
                        android:id="@+id/btn_cancel"

                    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: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，

        </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，

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();

创建自定义警报对话框

cumstomDialog.xml

    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"

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”;

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!

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>
