android 横竖屏切换 简记

横竖屏切换，不重新加载

1、activity声明android:configChanges="orientation|keyboardHidden|screenSize"

Up to API 13 there was a new value to the configChanges attribute, screenSize

So if you‘re using large screens make sure to add screenSize in your configChanges attribute:

android:configChanges="orientation|keyboardHidden|screenSize"

2、Activity重写onConfigurationChanged：
public void onConfigurationChanged(Configuration newConfig) {  
     super.onConfigurationChanged(newConfig);  
}  

--------------------------------------------------------------------------------------------

代码切换横竖屏

setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
