Firebase for Android, How can I loop through a child (for each child = x do y)

Question

This is what my test looks like:

I won\'t use the fields above, it\'s just a dummy. But I would like to go through all the children on \"users\" and for eac

Let say you have a reference to the node users, you can iterate through the nodes as follows:

reference.addValueEventListener(new ValueEventListener() {
        @Override
        public void onDataChange(DataSnapshot dataSnapshot) {
            for(DataSnapshot child : dataSnapshot.getChildren() ){
                // Do magic here
            }
        }

        @Override
        public void onCancelled(FirebaseError firebaseError) {}
    });

Note that the DataSnapshot child inside the for loop will have the UIDs as key, not users.
