检测设备方向时，活动的方向已被锁定 [英] Detect device orientation when Activity orientation is locked

问题描述

在我的项目，我一定要锁定一个活动的方向。 （我不能重新创建活动）

In my project, I have to lock the orientation of an activity. (I cannot recreate the activity)

我想，当用户改变说该设备的取向来显示消息：
的观点被锁定在这个位置......

I want to display a message when the user change the orientation of the device that say : "The View is locked in this position ..."

我可以很容易地与此code锁定方向：

I can easily lock the orientation with this code:

if(version >= Build.VERSION_CODES.JELLY_BEAN_MR2){
        activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LOCKED);
    }else{
        int orientation = activity.getResources().getConfiguration().orientation;
        if(orientation == ActivityInfo.SCREEN_ORIENTATION_PORTRAIT){
            activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
        }else{
            activity.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE);
        }
    }

有了这个code中的视图被锁定，但是当用户更改设备的方向我无法察觉。

With this code the view is locked but I cannot detect when the user change the device orientation.

如果我用这个下code：

And if I use this following code:

@Override
   public void onConfigurationChanged(Configuration newConfig) {
     //Check if the orientation has change
     if(newConfig.orientation != mOrientation){
        Toast.makeText(this, "Message for user", Toast.LENGTH_SHORT).show();
     }

     //Try to lock the view but not working
     newConfig.orientation = mOrientation;

     //Obligatory line that reload the view and cannot be delete
     //(is the biggest prolem of this code)
     super.onConfigurationChanged(newConfig);
   }

如果有人知道的方式来锁定观点和检测设备方向的变化，这将真正帮助我。

If someone know a way to lock the view and detect the change of the device orientation it will really help me.
