当指定了屏幕的方向后（非SCREEN_ORIENTATION_UNSPECIFIED），屏幕就不会自己主动的旋转了
有2中方式控制屏幕方向：
横屏：
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
竖屏：
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
ActivityInfo:
|

Constant corresponding to behind in the screenOrientation attribute. |
|

屏幕旋转后会强制调用Activity.onCreate方法，所以会重置Activity
禁止方法：
改动AndroidManifest.xml
android:configChanges=”orientation”
近期在做Android的播放器。遇到採用以上方法后，仍然出现屏幕旋转后触发Activity.onCreate，经查阅资料后，发现须要加入screenSize处理
详细代码为：
android:configChanges="orientation|keyboardHidden|screenSize"
Android 设定横屏，禁止屏幕旋转，Activity重置 [更新视频播放器相关]
