在Android中的orderbyvalue功能不起作用?

问题描述

我正在尝试按高分值进行排序，并且我搜索了以下示例:

解决方案

应该是这样的:

  highScoreRef.orderByValue().addChildEventListener(...){...} 

，或者如果您要先保存 Query 对象:

 查询查询= highScoreRef.orderByValue();query.addChildEventListener(...){...} 

I am trying to sort by highscore values and I have searched for examples like here: https://www.firebase.com/docs/android/guide/retrieving-data.html#section-queries

But still it doesn't work. I have tried to Log every step that I take but still no results. Please help me with this.

解决方案

It should be like this:

highScoreRef.orderByValue().addChildEventListener( ... ) { ... }

or if you want to save Query object first:

Query query = highScoreRef.orderByValue();
query.addChildEventListener( ... ) { ... }
