Android 嵌套 AlertDialog - 这可能吗？

在对数据库执行不可逆转的操作之前，我试图要求用户确认两次。问题在于外部单击处理程序不等待内部单击处理程序。单击第一个对话框上的“是”按钮后，会短暂显示第二个对话框，但外部处理程序仍然执行并完成，最终销毁两个对话框。

new AlertDialog.Builder(ActivityMain.this).setMessage(
  "Are you sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {

    new AlertDialog.Builder(ActivityMain.this).setMessage(
      "Are you really sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {

    ....

这是为什么？

I am trying to ask the user for confirmation twice before I do something irreversible to the database. The problem is that the outer click handler does not wait for the inner click handler. Once the Yes button is clicked on the first dialog, the 2nd dialog is displayed briefly, but the outer handler executes and completes nonetheless, ultimately destroying both dialogs.

new AlertDialog.Builder(ActivityMain.this).setMessage(
  "Are you sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {

    new AlertDialog.Builder(ActivityMain.this).setMessage(
      "Are you really sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {

    ....

Why is that?

只需设计一个新的 xml 布局作为您的对话框并创建一个新活动，并将其主题设置为活动标记下的清单文件中的 @android:style/Theme.Dialog：

<activity android:theme="@android:style/Theme.Dialog" android:name="LocationDialog"> </activity>

在对话框中单击侦听器代码启动活动，

new AlertDialog.Builder(ActivityMain.this).setMessage(
  "Are you sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {
             Intent i = new Intent(YourActivity.this, NewActivity.class);
             startActivity(i);
      }

如下所示您的新活动作为一个对话框，您可以在其中轻松应用您的操作。

Just Design a new xml layout as your dialog and create a new activity and set it's theme to @android:style/Theme.Dialog in the manifest file under the activity tag ex:

<activity android:theme="@android:style/Theme.Dialog" android:name="LocationDialog"> </activity>

in the Dialog click listener code start the activity as

new AlertDialog.Builder(ActivityMain.this).setMessage(
  "Are you sure?").setPositiveButton("Yes",
    new DialogInterface.OnClickListener() {
      public void onClick(DialogInterface arg0, int arg1) {
             Intent i = new Intent(YourActivity.this, NewActivity.class);
             startActivity(i);
      }

This will start your new activity as a dialog where you can apply your action easily.
