Filter query to populate FirebaseRecyclerAdapter

Question

This is still unclear how to populate FirebaseRecyclerAdapter with custom query.

1. Define a reference. Here: DatabaseReference ref = mDatabase.getReference().child("users");

2. Send it to adapter initAdapter(ref);

3. Define query and set listener. Is it right?

   mAdapter = new FirebaseRecyclerAdapter<User, UserHolder>(User.class,  R.layout.user_row_layout, UserHolder.class, ref) {
   
           @Override
           protected void populateViewHolder(final UserHolder viewHolder, final User model, int position) {
   
               Query query = ref.orderByChild("group").equalTo(uid);
               query.addChildEventListener(new ChildEventListener() {
                   @Override
                   public void onChildAdded(DataSnapshot dataSnapshot, String s) {
                       viewHolder.setName(model.getName());
                       viewHolder.setStatus(getStatus(model.getStatus()));
                   }
   
                   // ...
               };
   

Still showing all data from users. Need just to filter based on uid. Any clues?

Answer 1

For those who might have tried to make things over-complicated as me, or working at night, here is solution:

mAdapter = new FirebaseRecyclerAdapter<User, UserHolder>(
               User.class,  
               R.layout.user_row_layout, 
               UserHolder.class,
               ref.orderByChild("group").equalTo(uid)
) {
    @Override
    protected void populateViewHolder(final UserHolder viewHolder, final User model, int position) {

                viewHolder.setName(model.getName());
                viewHolder.setStatus(getStatus(model.getStatus()));
            }

            // ...
        };

Chao!
