廣播接收器的onReceive聊天功能

Question

我試圖建立與Android工作室聊天功能，但在收到消息時聊天屏幕不更新。

loadMsg（）;函數在發送消息時正在工作。但沒有收到。

這是代碼，我有：

@Override 
public void onStart() { 
    super.onStart(); 
    IntentFilter ief = new IntentFilter("test"); 
    registerReceiver(mReceiver, ief); 
} 

private BroadcastReceiver mReceiver = new BroadcastReceiver() { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
     // Show("Intent Receved"); 
     if (intent.getAction().equals("test")) { 
      // Do stuff 
      loadMsg(); 
     } 
    } 
}; 

public void loadMsg() 
{ 
    ParseUser par=room.getParseUser("unreadBy"); 
    try{ 
     par.fetchIfNeeded(); 
     currentUser.fetchIfNeeded(); 
    }catch (Exception e){} 
    if(par!=null) 
    { 
     if(par.getObjectId().equals(currentUser.getObjectId())) 
     { 
      room.put("unread",0); 
      room.saveInBackground(null); 
     } 
    } 

    final ParseQuery<ParseObject> msgQ=new ParseQuery("Messages"); 
    msgQ.whereEqualTo("match",room); 
    msgQ.orderByAscending("createdAt"); 
    msgQ.setLimit(500); 
    msgQ.include("user"); 
    msgQ.findInBackground(new FindCallback<ParseObject>() { 
     @Override 
     public void done(List<ParseObject> objects, ParseException e) { 
      if(e==null) { 
       Log.d(tag, "Messges--" + objects.size()); 
       msgObj = objects; 
       if(msgObj.size()>0) { 
        empty.setVisibility(View.INVISIBLE); 
        try { 
         adapter = new AwesomeAdapter(getApplicationContext(), msgObj, currentUser, selfbit, incbit); 
         lv.setAdapter(adapter); 
         lv.setSelection(msgObj.size() - 1); 
        }catch (Exception eg){} 
       } 

      }else{ 
       Log.d(tag, "eror--" + e); 
      } 
     } 
    }); 
}

      --> 
      <category android:name="com.package.name" /> 
     </intent-filter> 
    </receiver> 

任何想法，我做錯了嗎？

嘗試改變

if (intent.getAction().equals("test")) { 
     // Do stuff 
     loadMsg(); 
    } 

到

if (intent.getAction().equals("test")) { 
     // Do stuff 
     runOnUiThread(new Runnable() { 
      @Override 
      public void run() { 
       loadMsg(); 
      } 
     }); 
    }
