Android横竖屏切换不重新调用onCreate()

再次感叹Android的碎片化!!!!

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>

@Override

public 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)

    { 

    }

}
