Android 设定横屏,禁止屏幕旋转,Activity重置 [更新视频播放器相关]
1. 设定屏幕方向
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:
1.1 改动AndroidManifest.xml
1.2 setRequestedOrientation
横屏:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
竖屏:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
ActivityInfo:
int |
Constant corresponding to behind in the screenOrientation attribute. |
|
int |
Constant corresponding to fullSensor in the screenOrientation attribute. |
|
int |
Constant corresponding to fullUser in the screenOrientation attribute. |
|
int |
Constant corresponding to landscape in the screenOrientation attribute. |
|
int |
Constant corresponding to locked in the screenOrientation attribute. |
|
int |
Constant corresponding to nosensor in the screenOrientation attribute. |
|
int |
Constant corresponding to portrait in the screenOrientation attribute. |
|
int |
Constant corresponding to reverseLandscape in the screenOrientation attribute. |
|
int |
Constant corresponding to reversePortrait in the screenOrientation attribute. |
|
int |
Constant corresponding to sensor in the screenOrientation attribute. |
|
int |
Constant corresponding to sensorLandscape in the screenOrientation attribute. |
|
int |
Constant corresponding to sensorPortrait in the screenOrientation attribute. |
|
int |
Constant corresponding to unspecified in the screenOrientation attribute. |
|
int |
Constant corresponding to user in the screenOrientation attribute. |
|
int |
Constant corresponding to userLandscape in the screenOrientation attribute. |
|
int |
Constant corresponding to userPortrait in the screenOrientation attribute. |
2. 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:
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"
禁止重置Activity会造成Screen的宽高颠倒, 须要手动修正。
