設(shè)定屏幕方向
當(dāng)指定了屏幕的方向后，屏幕就不會(huì)自動(dòng)的旋轉(zhuǎn)了

有2種方式控制屏幕方向：

修改AndroidManifest.xml

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

2 setRequestedOrientation
橫屏：
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
豎屏：
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.

2. 禁止 屏幕旋轉(zhuǎn)后重置Activity

屏幕旋轉(zhuǎn)后會(huì)強(qiáng)制調(diào)用Activity.onCreate方法，所以會(huì)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，仍然出現(xiàn)屏幕旋轉(zhuǎn)后觸發(fā)Activity.onCreate，經(jīng)查閱資料后，發(fā)現(xiàn)需要添加screenSize處理
具體代碼為：

android:configChanges="orientation|keyboardHidden|screenSize"
