Parse.com通过查询获得价值

Parse的Android指南在这里有一个基本的查询示例，它将返回与您的约束匹配的第一个对象：

ParseQuery<ParseObject> query = ParseQuery.getQuery("YourClassName");query.whereEqualTo("ID", "someID");query.getFirstInBackground(new GetCallback<ParseObject>() {  public void done(ParseObject object, ParseException e) {    if (object == null) {      Log.d("score", "The getFirst request failed.");    } else {      Log.d("score", "Retrieved the object.");    }  }});
