1.创建自定义对话框并根据您的需求进行调整，例如： G。 my_dialog.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="@+id/tv_dialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Text"/>
<Button
android:id="@+id/btn_dialog"
android:layout_width="match_parent"
android:layout_height="40dp"
android:layout_below="@+id/tv_dialog"
android:text="Button"/>
</RelativeLayout>
2.Declare并从活动中打开对话框：
my_dialog = new Dialog(context);
my_dialog .requestWindowFeature(Window.FEATURE_NO_TITLE);
my_dialog .setCancelable(true);
my_dialog .setContentView(R.layout.my_dialog);
my_dialog.show();
