推荐答案

This isable;查看 windowContentOverlay 属性.特别是，您可以创建一个新的主题:

This is themable; look at the windowContentOverlay attribute. In particular, you can create a new theme:

<style name="Theme.Foo" parent="android:style/Theme.Light">
    <item name="android:windowContentOverlay">@null</item>
</style>

然后声明你的活动应该使用这个主题:

And then declare that your activity should use this theme:

<activity android:name=".FooActivity"
          android:theme="@style/Theme.Foo"> ...

虽然更好的选择是为应用程序中的所有活动设置这个主题，以保持一致性:

Although a better option is to set this theme for all activities in the application, for consistency:

<application android:theme="@style/Theme.Foo"> ...
