在 AndroidManifest.xml里添加

<activity android:name=".YourActivityName"
             android:configChanges="keyboardHidden|orientation">

在activity, override this method:-

@Override
public void onConfigurationChanged(Configuration newConfig)
{
                if (getResources().getConfiguration().orientation ==
Configuration.ORIENTATION_LANDSCAPE)
        {
                                       //do your task
        }
        else if (getResources().getConfiguration().orientation ==
Configuration.ORIENTATION_PORTRAIT)
        {
                                      //do your task
        }
        super.onConfigurationChanged(newConfig);

 

}
