我所做的是在显示对话框时锁定方向，然后在完成时将其解锁：

int currentOrientation = getResources().getConfiguration().orientation;
        if (currentOrientation == Configuration.ORIENTATION_LANDSCAPE) {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_LANDSCAPE); //locks landscape
        }
        else {
            setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR_PORTRAIT); //locks port
        }
    // do work
    setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
