嗨，我做了一个活动，我打开一个活动作为另一个活动的对话框弹出窗口，所以我知道这是我的主题的问题，

 <item `name="android:windowCloseOnTouchOutside">@bool/config_closeDialogWhenTouchOutside</item>`

但我不知道我应该在里面更改什么值，"windowCloseOnTouchOutside"以便我可以将我的活动对话框设置为可取消 false..？我的主题代码如下：

 <style name="Theme.Dialog">
        <item name="android:windowFrame">@null</item>
        <item name="android:windowTitleStyle">@android:style/DialogWindowTitle</item>
        <item name="android:windowBackground">@android:drawable/panel_background</item>
        <item name="android:windowIsFloating">true</item>
        <item name="android:windowContentOverlay">@null</item>
        <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
        <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
        <item name="android:windowCloseOnTouchOutside">@bool/config_closeDialogWhenTouchOutside</item>
        <item name="android:windowActionModeOverlay">true</item>

        <item name="android:colorBackgroundCacheHint">@null</item>

        <item name="textAppearance">@android:style/TextAppearance</item>
        <item name="textAppearanceInverse">@android:style/TextAppearance.Inverse</item>

        <item name="textColorPrimary">@android:color/primary_text_dark</item>
        <item name="textColorSecondary">@android:color/secondary_text_dark</item>
        <item name="textColorTertiary">@android:color/tertiary_text_dark</item>
        <item name="textColorPrimaryInverse">@android:color/primary_text_light</item>
        <item name="textColorSecondaryInverse">@android:color/secondary_text_light</item>
        <item name="textColorTertiaryInverse">@android:color/tertiary_text_light</item>
        <item name="textColorPrimaryDisableOnly">@android:color/primary_text_dark_disable_only</item>
        <item name="textColorPrimaryInverseDisableOnly">@android:color/primary_text_light_disable_only</item>
        <item name="textColorPrimaryNoDisable">@android:color/primary_text_dark_nodisable</item>
        <item name="textColorSecondaryNoDisable">@android:color/secondary_text_dark_nodisable</item>
        <item name="textColorPrimaryInverseNoDisable">@android:color/primary_text_light_nodisable</item>
        <item name="textColorSecondaryInverseNoDisable">@android:color/secondary_text_light_nodisable</item>
        <item name="textColorHint">@android:color/hint_foreground_dark</item>
        <item name="textColorHintInverse">@android:color/hint_foreground_light</item>
        <item name="textColorSearchUrl">@android:color/search_url_text</item>

        <item name="textAppearanceLarge">@android:style/TextAppearance.Large</item>
        <item name="textAppearanceMedium">@android:style/TextAppearance.Medium</item>
        <item name="textAppearanceSmall">@android:style/TextAppearance.Small</item>
        <item name="textAppearanceLargeInverse">@android:style/TextAppearance.Large.Inverse</item>
        <item name="textAppearanceMediumInverse">@android:style/TextAppearance.Medium.Inverse</item>
        <item name="textAppearanceSmallInverse">@android:style/TextAppearance.Small.Inverse</item>

        <item name="listPreferredItemPaddingLeft">10dip</item>

你可以很容易地在 Java 编码中做到这一点。如果你有一个活动（即使它看起来像一个对话框），那么你应该这样做

this.setFinishOnTouchOutside(false);

如果你使用过 Dialog 类，你应该调用

dialog.setFinishOnTouchOutside(false)

如果您想防止在单击后台活动时将其关闭。

这可以帮助你。这是一种处理外部触摸事件的方法：

在窗口外触摸时如何取消以 Activity 为主题的对话框？

有一种方法可以从以对话框为主题的 Activity 中获得类似对话框的“触摸外部取消”行为，尽管我还没有完全调查它是否有不需要的副作用。

在您的 ActivityonCreate()方法中，在创建视图之前，您将在窗口上设置两个标志：一个使其成为“非模态”，允许您的 Activity 视图以外的视图接收事件。第二个是接收其中一个事件已发生的通知，这将向您发送一个ACTION_OUTSIDE移动事件。

尝试如下：

public class MyActivity extends Activity {

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

    // Make us non-modal, so that others can receive touch events.
    getWindow().setFlags(LayoutParams.FLAG_NOT_TOUCH_MODAL, LayoutParams.FLAG_NOT_TOUCH_MODAL);

    // ...but notify us that it happened.
    getWindow().setFlags(LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH, LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH);

    // Note that flag changes must happen *before* the content view is set.
    setContentView(R.layout.my_dialog_view);
  }

  @Override
  public boolean onTouchEvent(MotionEvent event) {
    // If we've received a touch notification that the user has touched
    // outside the app, finish the activity.
    if (MotionEvent.ACTION_OUTSIDE == event.getAction()) {
      finish();
      return true;
    }

    // Delegate everything else to Activity.
    return super.onTouchEvent(event);
  }
}

最好的方法是这段代码：

AlertDialog.Builder alert = new AlertDialog.Builder(Activity.this);
alert.setCancelable(false);
