锁定屏幕旋转但仍然可以检测到

Question

I m building an app which an a main layout in portrait format

I locking orientation with

 setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); 

However, I need to detect screen orientation changes anyway because I want to load another Activity if the screen is rotated.

How to do that ?

I tryed onConfigurationChanged but it s never called.

Answer 1

Some things to look at if onConfigurationChanged isn't firing:

When you declare the manifest, make sure you have defined at least orientation and screenSize for the activity configChanges. Like this:

<activity android:name="com.test.act" android:configChanges="orientation|screenSize">

Make sure the device doesn't have rotation blocked. For example if you are using a Nexus 7:
