Summary of the method of setting full-screen untitled in Android ActionBarActivity

The newly created Activity inherits from ActionBarActivity. It is easy to set full screen without titles, but I didn’t expect that the app would hang for no reason, either with a white screen or a black screen. I've cheated on me for more than an hour! ! !

The reason is that when setting the ActionBarActivity theme, you can only use the theme starting with *** in the v7 package. Therefore, if you set the full screen without title, you need to customize a style:

<style name="ActionBarFullScreen" parent="">
  <item name="android:windowFullscreen">true</item>
  <item name="android:windowNoTitle">true</item>
  <item name="android:windowContentOverlay">@null</item>
</style>

Then in: Set android:theme="@style/ActionBarFullScreen" and it's OK!

Another solution is to change the inherited ActionBarActivity to FragmentActivity or Activity, and then set the theme directly

Android:theme="@android:style/"It's OK!
