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>

@Overridepublic void onConfigurationChanged(Configuration newConfig){super.onConfigurationChanged(newConfig);if(this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){Log.v(TAG, "ORIENTATION_LANDSCAPE");}if(this.getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT){Log.v(TAG, "ORIENTATION_PORTRAIT");}    if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_NO)    {     }     else if (newConfig.hardKeyboardHidden == Configuration.HARDKEYBOARDHIDDEN_YES)    {     }}
