android中按电源键锁屏然后解锁导致Activity调用onDestory以及如何防止锁屏 翻转屏幕也会触发的情况

设置AndroidManifest.xml中Activity的Android:configChanges=”keyboardHidden|orientation|screenSize”
Android4.0需设置screenSize才有效果.
2.2,2.3这些只需设置keyboardHidden|orientation
4.0 –> keyboardHidden|orientation|screenSize

<activity              android:name=".MainActivity"              android:configChanges="keyboardHidden|orientation|screenSize"              android:label="@string/app_name" >              <intent-filter>                  <action android:name="android.intent.action.MAIN" />                  <category android:name="android.intent.category.LAUNCHER" />              </intent-filter>  </activity>
