android - 我的 android Activity 如何知道设备何时改变方向

Question

你能告诉我当屏幕方向发生变化时，我的 android Activity 如何知道(是否有回调)？

谢谢。

Answer 1

看看 Activity 的 public void onConfigurationChanged(Configuration newConfig) 方法:

http://developer.android.com/reference/android/app/Activity.html#onConfigurationChanged%28android.content.res.Configuration%29

注意这个:

Note that this will only be called if you have selected configurations you would like to handle with the configChanges attribute in your manifest.
