Retrieve data from Firebase into Listview
<p>I am trying to retrieve data from Firebase but nothing pulls through. The app is written successfully however when it tries to get the info back it just shows a blank screen. My Firebase structure is <code>Saica&gt;Calendar&gt;key&gt;Data</code></p>

<p>I have included a picture of my Firebase Structure </p>

<p>This is my code:</p>

<pre><code>public class Admin_ViewEvent extends AppCompatActivity {

private ListView mListView;
private ArrayList&lt;String&gt; mMeetings = new ArrayList&lt;&gt;();
private Firebase mRef;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_admin__view_event);

    mRef = new Firebase("https://saica-sgb-77a4f.firebaseio.com/Meetings");
    mListView = (ListView) findViewById(R.id.ListView);

    final ArrayAdapter&lt;String&gt; arrayAdapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, mMeetings);
    mListView.setAdapter(arrayAdapter);

    mRef.addChildEventListener(new ChildEventListener() {
        @Override
        public void onChildAdded(DataSnapshot dataSnapshot, String s) {
            String value = dataSnapshot.getValue(String.class);
            mMeetings.add(value);
            arrayAdapter.notifyDataSetChanged();
        }

        @Override
        public void onChildChanged(DataSnapshot dataSnapshot, String s) {

        }
</code></pre>
