怎么在做转屏的时候不销毁当前Activity

For API 12 and below: add

android:configChanges="orientation"

Add "screenSize" if you are targeting API 13 or above because whenever your orientation changes so does your screen size, otherwise new devices will continue to destroy your activity. 

android:configChanges="orientation|screenSize"

to your Activity in AndroidManifest.xml. This way your Activity wont be restarted automatically.
