获取当前方向并锁定

Question

I'm trying to get the current orientation of an activity and lock it like this but it just goes to portrait even when opened in landscape mode.

//getRequestedOrientation();
setRequestedOrientation( ActivityInfo.SCREEN_ORIENTATION_LOCKED);

Thanks

Answer 1

You have screen orientation locked, it will show your app in portrait mode, you should use screen orientation sensor.

setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_SENSOR);   

Edit.

int str = 0;
    try {
            str = Settings.System.getInt(contexto.getContentResolver(),Settings.System.ACCELEROMETER_ROTATION);
        } catch (SettingNotFoundException e) {          
                e.printStackTrace();
        } 
    if(str!=0) 
    {
        setRequestedOrientation (ActivityInfo.SCREEN_ORIENTATION_SENSOR);   
    }

This seems to do the trick:

if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_PORTRAIT) {
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
} else setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
