title: Navigation Drawer issue
body: <p>I've been following the offical guide of google to create a simple Navigation Drawer. So far I 've changed my Main_Activity.xml layout to this:</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout
      xmlns:android="http://schemas.android.com/apk/res/android"
      android:id="@+id/drawer_layout"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
      &lt;!-- The main content view --&gt;
      &lt;FrameLayout
          android:id="@+id/content_frame"
          android:layout_width="match_parent"
          android:layout_height="match_parent" /&gt;
      &lt;!-- The navigation drawer --&gt;
      &lt;ListView android:id="@+id/drawer_list"
          android:layout_width="240dp"
          android:layout_height="match_parent"
          android:layout_gravity="start"
          android:choiceMode="singleChoice"
          android:divider="@android:color/transparent"
          android:dividerHeight="0dp"
          android:background="#111"/&gt; 
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
  
  <p>Then on my MainActivity.java I added these:</p>
  
  <pre><code>    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
      mDrawerList = (ListView) findViewById(R.id.drawer_list);
  
      // Creating an ArrayAdapter to add items to the listview mDrawerList
      ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(getBaseContext(), 
              R.layout.drawer_list_item, mOptions);
  
      // Setting the adapter on mDrawerList
      mDrawerList.setAdapter(adapter);
  </code></pre>
  
  <p>I've also created the XML drawer_list_item with the following</p>
  
  <pre><code> &lt;TextView xmlns:android="http://schemas.android.com/apk/res/android"
       android:id="@android:id/text1"
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:textAppearance="?android:attr/textAppearanceListItemSmall"
       android:gravity="center_vertical"
       android:paddingLeft="16dp"
       android:paddingRight="16dp"
       android:textColor="#fff"
       android:background="?android:attr/activatedBackgroundIndicator"
       android:minHeight="?android:attr/listPreferredItemHeightSmall"/&gt;
  </code></pre>
  
  <p>Yet still I have nothing, not even an error. It just doesn't work, I think I am missing some simple, Thanks!</p>
