android - Set Actionbar overlay mode at runtime in Android

Question

How do I set the actionbar mode at runtime to not-overlay or overlay with the content at runtime? I tried using getWindow().requestFeature(Window.FEATURE_ACTIONBAR_OVERLAY) but it doesn't allow to set the mode after calling setContentView(). This can be done, as I have seen it being done in the Youtube app.

尽管不一定完全符合您的要求，但一种体面的解决方法是在内容顶部创建一个与 ActionBar 高度相同的间隔视图 (android:layout_height="?android:actionBarSize")。当您想要启用覆盖模式时，将间隔的可见性设置为 View.GONE，当您想要禁用它时，将其设置为 View.VISIBLE。
