Как сделать сортировку по значению true , firebase database android?

База выглядит таким образом, в ключе "stars" будут создаваться ключи с id пользователей.У них есть значения true или false. Мне же нужно сделать запрос , что бы он находил свой id и проверял если значение истина , то показывать в списке,если ложно , то не отображать в списке. public abstract class PostListFragment extends Fragment { private Activity mActivity; private DatabaseReference mDatabase; private FirebaseRecyclerAdapter mAdapter; private RecyclerView mRecycler;
