requestWindowFeature(Window.FEATURE_NO_TITLE);//隐藏标题 getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);//设置全屏
@Override
protected void onResume() {
/**
* 设置为横屏
*/
if(getRequestedOrientation()!=ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE) {
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
}
super.onResume();
}
2、在配置文件中对Activity节点添加android:screenOrientation属性(landscape是横向，portrait是纵向)
android:launchMode="singleTask"
android:screenOrientation="portrait"
view.setKeepScreenOn(true)
