安卓Android中强制设置横屏或者竖屏

@Override
protected void onResume() {
/**
* 设置为横屏
*/
if(getRequestedOrientation()!= ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE){
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
super.onResume();
}

SCREEN_ORIENTATION_LANDSCAPE

代码如下：：

@Override
protected void onResume() {
/**
* 设置为竖屏
*/
if(getRequestedOrientation()!= ActivityInfo.SCREEN_ORIENTATION_PORTRAIT){
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}
super.onResume();
}
