title: Firebase get all data of nodes
body: <p>I have trouble to get datas from my node. I'm showing datas in listview.
  <a href="https://i.stack.imgur.com/QQkjc.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/QQkjc.png" alt="Firebase"></a></p>
  
  <p>The top of the uid stars with "VVAA.." is my user's uid. I can reach datas of "34ern12" node. (Btw we don't define this node's name. Users do.) But I want to reach other node's datas. I mean I want to reach all datas of nodes of my useruid node. How I can do this? Do you have an idea?</p>
  
  <p>Here is my code:</p>
  
  <pre><code>    firebaseAuth=FirebaseAuth.getInstance();
      userId=firebaseAuth.getCurrentUser().getUid().toString();
      listview=(ListView)view.findViewById(R.id.listview);
      adapter=new ArrayAdapter&lt;String&gt;(getActivity(),R.layout.support_simple_spinner_dropdown_item,list);
      listview.setAdapter(adapter);
  
  
     datareference= FirebaseDatabase.getInstance().getReference().child("Arabalar").child(userId).child("34ern12");
  
  
      datareference.addChildEventListener(new ChildEventListener() {
          @Override
          public void onChildAdded(DataSnapshot dataSnapshot, String s) {
              String value=dataSnapshot.getValue(String.class);
              list.add(value);
              adapter.notifyDataSetChanged();
          }
  
          @Override
          public void onChildChanged(DataSnapshot dataSnapshot, String s) {
  
          }
  
          @Override
          public void onChildRemoved(DataSnapshot dataSnapshot) {
  
              String value=dataSnapshot.getValue(String.class);
              list.remove(value);
              adapter.notifyDataSetChanged();
  
          }
  
          @Override
          public void onChildMoved(DataSnapshot dataSnapshot, String s) {
  
          }
  
          @Override
          public void onCancelled(DatabaseError databaseError) {
  
          }
      });
  
      FloatingActionButton fab = (FloatingActionButton) view.findViewById(R.id.fab);
      fab.setOnClickListener(new View.OnClickListener()
      {
          @Override
          public void onClick(View view) {
              startActivity(new Intent(getActivity(),AracEkle.class));
          }
      });
  
      return view;
  
  }}
  </code></pre>
