ParseQueryAdapter.setAutoLoad（true）不刷新数据

Question

我想自动加载更新到解析云的数据。我正在使用ParseQueryAdapter从Parse请求更新的数据。我还设置了commentsQueryAdapter.setAutoLoad（true），但它仍不刷新数据。

//Set up a customized query 
    final ParseQueryAdapter.QueryFactory<ParseCommentsClass> factory = 
      new ParseQueryAdapter.QueryFactory<ParseCommentsClass>() { 
       public ParseQuery<ParseCommentsClass> create() { 
        ParseQuery<ParseCommentsClass> query = ParseCommentsClass.getQuery(); 
        query.whereEqualTo("videoId", videoID); 
        query.setCachePolicy(ParseQuery.CachePolicy.NETWORK_ELSE_CACHE); 
        query.orderByDescending("createdAt"); 
        return query; 
       } 
      }; 

    // Set up the query adapter 
    commentsQueryAdapter = new ParseQueryAdapter<ParseCommentsClass>(this, factory) { 
     @Override 
     public View getItemView(final ParseCommentsClass post, View view, ViewGroup parent) { 
      if (view == null) { 
       view = View.inflate(getContext(), R.layout.comments_layout, null); 
      } 
      ImageView ProfileView = (ImageView) view.findViewById(R.id.profilePic); 
      TextView usernameView = (TextView) view.findViewById(R.id.name); 
      TextView commentsView = (TextView)view.findViewById(R.id.comments); 
      String ProfileThumb = String.valueOf(post.getUserPic().getUrl()); 
      Picasso.with(SingleVideoView.this) 
        .load(ProfileThumb) 
        .transform(new CircleTransform()) 
        .resize(70,70) 
        .centerCrop() 
        .into(ProfileView); 

      usernameView.setText(post.getUser()); 
      commentsView.setText(post.getComment()); 
      return view; 
     } 
    }; 

    // Disable pagination, we'll manage the query limit ourselves 
    // commentsQueryAdapter.setPaginationEnabled(false); 
    listView = (ListView)findViewById(R.id.comments_list); 
    listView.setAdapter(commentsQueryAdapter); 
    commentsQueryAdapter.setAutoload(true); 
}

好吧我找到了一种方法来实现Parse Cloud的间隔刷新。

private Timer autoUpdate; 

    @Override 
     protected void onResume(){ 
      super.onResume(); 
      autoUpdate = new Timer(); 
      autoUpdate.schedule(new TimerTask() { 
       @Override 
       public void run() { 
        runOnUiThread(new Runnable() { 
         public void run() { 
          commentsQueryAdapter.loadObjects(); 
         } 
        }); 
       } 
      }, 0, 1500); // updates each 40 secs 
     }
