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)
	    { 
	    }
	}
