获取Firebase数据库的所有子项的数据

我有一个带有孩子的Firebase数据库users.这包含两个用户user1和user2.他们每个都包含name和address.现在,我需要得到的价值name和address中user1和user2.

提前致谢.

DatabaseReference ref1= FirebaseDatabase.getInstance().getReference();
  DatabaseReference ref2;    
   ref2 = ref1.child("users");


   ref2.addListenerForSingleValueEvent(new ValueEventListener() {
    @Override
    public void onDataChange(DataSnapshot dataSnapshot) {

        Userlist = new ArrayList();                

        // Result will be holded Here
        for (DataSnapshot dsp : dataSnapshot.getChildren()) {
            Userlist.add(String.valueOf(dsp.geValue())); //add result into array list


        }
