Firebase add new child with specified name

Question

This is my database

I'd like to add new users to database keeping that format. I've tried this:

   //Store data in database
    Firebase usersRef = ref.child("Users");
    Map<String, String> userData = new HashMap<String, String>();

    userData.put("Nombre", name);
    userData.put("Password", pass);
    userData.put("Confirmed", "FALSE");
    userData.put("Email", mail);

    usersRef.setValue(name);
    usersRef = ref.child("Users").child(name);
    usersRef.setValue(userData);

The problem is whenever I add a new user, the previous one is overwritten.

Answer 1

It happens because you are using:

Firebase usersRef = ref.child("Users");
usersRef.setValue(name);

In this way you will push the value in url/Users removing the previous value.

Check the doc:

Using setValue() will overwrite the data at the specified location, including any child nodes.

To add a new user without removing the previous one , just remove this line:

//usersRef.setValue(name);

In this way you will push the value in url/Users/myName without overriding other values.
