如何删除firebase android中的子节点？ [英] How to remove child nodes in firebase android?

问题描述

Firebase数据库中有许多子节点，我只想删除一个子节点。

  Firebase firebase = new Firebase（.. address ..）; 
 
 firebase.push（）。setValue（classObj）; 
  

//这里classObj是一个类对象，它有一个getter和setter作为整数id

现在我已经推入了多个对象，我只想删除一个基于id的classObj中的一个

解决方案

  firebase.child（id）.removeValue（）; 
  

您可以查看一下Android btw的Firebase文档，更多主题。

I have a number of child nodes in my firebase db and I want to delete only one child node.

Firebase firebase=new Firebase("..address..");

firebase.push().setValue(classObj);

//here classObj is a class object which has a getter and setter for an integer id

Now that I have pushed multiple objects I want to delete only one based on the id in the classObj

解决方案

To remove data:

firebase.child(id).removeValue();

You might do well to have a look at the Firebase documentation for Android btw, which covers this and many more topics.
