你如何在parse.com上增加

我无法在parse.com上增加值。没有任何反应,价值保持为0。

首先我在postactivity中将值设置为0:

Counter count = new Counter();
int Counts = 0;
count.setVote(counts);
count.saveInBackground();

在我的parse.com课上,我有:

public int getVote() {
    return getInt("vote");
}

public void setVote(int value) {
    put("vote",value");
}

MainActivity我有:

public View getItemView(final Counter count,View view,ViewGroup parent) {
    if(view==null) {
        view = View.inflate(getContent(),R.layout.count_item,null);
    }

    ImageButton vote=(ImageButton) view.findViewById(R.id.btnvoteup);
    vote.setOnClickListener(new View.OnClickListener() {
            public void onClick(View v) {
                count.increment("vote",1);
                count.saveInBackground();
            }
        });
    return view;
}

以前使用的代码,我不确定发生了什么变化导致它停止工作。

我不知道这是否是您想要做的,但如果您想将计数器增加1,请创建一个类型为数字的列并执行此操作:

ParseQuery<ParseObject> query = ParseQuery.getQuery("ClassName");

// Retrieve the object by id
query.getInBackground("xWMyZ4YEGZ", new GetCallback<ParseObject>() {
  public void done(ParseObject myobject, ParseException e) {
    if (e == null) {
      // Now let's update it with some new data. In this case, only cheatMode and score
      // will get sent to the Parse Cloud. playerName hasn't changed.
     myobject.increment("score");
     myobject.saveInBackground();
    }
  }
});
