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>
