从 Parse.com 中的对象 ID 获取数据 [英] Getting data from object Id in Parse.com

问题描述

我遇到了一些与 parse.com 相关的问题我想获取特定 objectId 的数据...我使用以下代码来获取数据，但似乎已折旧...因为它在异常后返回

I am facing some problem related to parse.com I want to fetch the data for a perticular objectId...I have used following code to get the data but seems it is depreciated..as it returned following exception

no results found for query

我使用以下代码来获取数据表单objectId:

I have used following code to get the data form objectId:

ParseQuery<ParseObject> query = new ParseQuery<ParseObject>("User");
    query.getInBackground("U8mCwTHOaC", new GetCallback() {
      public void done(ParseObject object, ParseException e) {
            Log.d(">>>", "0000>>>" +objid);
        dlg.dismiss();
        if (e == null) {
          // object will be your game score
             Log.d(">>",">>"+object);
        } else {
          // something went wrong
             Log.d(">>",">>"+e);
        }
      }
    });

这里U8mCwTHOAC"是我的objectId，我想获取这个objectId的行.提前谢谢..

Here "U8mCwTHOaC" is my objectId,I want to fetch the row of this objectId.Thanks in advance..

推荐答案

如果你想从用户表中获取数据.

if you want to get data from user table.

ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
    query.whereEqualTo("objectId","U8mCwTHOaC");
    query.findInBackground(new FindCallback<ParseObject>() {
        public void done(List<ParseObject> objects, ParseException e) {
            if (e == null) {
                // row of Object Id "U8mCwTHOaC"
            } else {
                // error
            }
        }
    });

如果你想要当前用户的行

if you want the row of current user

 ParseQuery<ParseObject> query = ParseQuery.getQuery("_User");
    query.whereEqualTo("objectId",ParseUser.getCurrentUser().getObjectId());
    query.findInBackground(new FindCallback<ParseObject>() {
        public void done(List<ParseObject> objects, ParseException e) {
            if (e == null) {
                // row of Object Id "Current USer"
            } else {
                // error
            }
        }
    });
