我怎样才能在我的屏幕上方摆脱梯度（下面的截图蓝色的顶部...通知栏下面）？

How can I get rid of the gradient at the top of my screen (the very top of the blue in the screenshot below... below the notification bar)?

推荐答案

这是主题化;看 windowContentOverlay 属性。特别是，你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>

然后宣布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"> ...

虽然一个更好的选择是设定这个主题为应用程序中的所有活动，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"> ...
