转自：http://blog.csdn.net/u012364372/article/details/51088831

设定屏幕方向
当指定了屏幕的方向后，屏幕就不会自动的旋转了

有2种方式控制屏幕方向：

修改AndroidManifest.xml

1 在AndroidManifest.xml的activity中加入:
横屏：
android:screenOrientation=”landscape”
竖屏：
android:screenOrientation=”portrait”

2 setRequestedOrientation
横屏：
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
竖屏：
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);

ActivityInfo:

int SCREEN_ORIENTATION_BEHIND Constant corresponding to behind in the screenOrientation attribute.

intSCREEN_ORIENTATION_FULL_SENSOR Constant corresponding to fullSensor in the screenOrientation attribute.

int SCREEN_ORIENTATION_FULL_USER Constant corresponding to fullUser in the screenOrientation attribute.

int SCREEN_ORIENTATION_LANDSCAPE Constant corresponding to landscape in the screenOrientation attribute.

int SCREEN_ORIENTATION_LOCKED Constant corresponding to locked in the screenOrientation attribute.

int SCREEN_ORIENTATION_NOSENSOR Constant corresponding to nosensor in the screenOrientation attribute.

int SCREEN_ORIENTATION_PORTRAIT Constant corresponding to portrait in the screenOrientation attribute.

int SCREEN_ORIENTATION_REVERSE_LANDSCAPE Constant corresponding to reverseLandscape in the screenOrientation attribute.

int SCREEN_ORIENTATION_REVERSE_PORTRAIT Constant corresponding to reversePortrait in the screenOrientation attribute.

int SCREEN_ORIENTATION_SENSOR Constant corresponding to sensor in the screenOrientation attribute.

int SCREEN_ORIENTATION_SENSOR_LANDSCAPE Constant corresponding to sensorLandscape in the screenOrientation attribute.

int SCREEN_ORIENTATION_SENSOR_PORTRAIT Constant corresponding to sensorPortrait in the screenOrientation attribute.

int SCREEN_ORIENTATION_UNSPECIFIED Constant corresponding to unspecified in the screenOrientation attribute.

int SCREEN_ORIENTATION_USER Constant corresponding to user in the screenOrientation attribute.

int SCREEN_ORIENTATION_USER_LANDSCAPE Constant corresponding to userLandscape in the screenOrientation attribute.

int SCREEN_ORIENTATION_USER_PORTRAIT Constant corresponding to userPortrait in the screenOrientation attribute.

禁止屏幕旋转后重置Activity

屏幕旋转后会强制调用Activity.onCreate方法，所以会重置Activity
禁止方法：
修改AndroidManifest.xml

configChanges=”orientation”

最近在做Android的播放器，遇到采用以上方法后，仍然出现屏幕旋转后触发Activity.onCreate，经查阅资料后，发现需要添加screenSize处理
具体代码为：

android:configChanges="orientation|keyboardHidden|screenSize"
