title: Android Remove Shadow On Navigation Drawer
body: <p><a href="http://marcoaprea.altervista.org/shadow.jpg" rel="noreferrer">See here what i mean</a></p>
  
  <p>Hi, I'm using stock Navigation drawer v4 and i ask how can delete that background shadow when navigation drawer is open.</p>
  
  <p>this is my code of NavigationDrawerFragment.java</p>
  
  <pre><code>public void setUp(int fragmentId, DrawerLayout drawerLayout) {
      mFragmentContainerView = getActivity().findViewById(fragmentId);
      mDrawerLayout = drawerLayout;
  
      // set a custom shadow that overlays the main content when the drawer opens
      mDrawerLayout.setDrawerShadow(R.drawable.trasparent, GravityCompat.START);
      // set up the drawer's list view with items and click listener
  
      ActionBar actionBar = getActionBar();
      actionBar.setDisplayHomeAsUpEnabled(true);
      actionBar.setHomeButtonEnabled(true);
  </code></pre>
  
  <p>And this is MainActivity.xml</p>
  
  <pre><code>&lt;android.support.v4.widget.DrawerLayout
      android:id="@+id/drawer_layout"
      android:layout_width="match_parent"
      android:layout_height="match_parent"&gt;
  
      &lt;!-- Main layout --&gt;
      &lt;FrameLayout
          android:id="@+id/main_fragment_container"
          android:layout_width="match_parent"
          android:layout_height="match_parent" /&gt;
  
  
      &lt;ImageView
          android:id="@+id/ImageView3_Left"
          android:layout_width="match_parent"
          android:layout_height="match_parent"
          /&gt;
  
      &lt;!-- The navigation drawer --&gt;
      &lt;ListView android:id="@+id/left_drawer"
          android:layout_width="240dp"
          android:layout_height="match_parent"
          android:layout_gravity="start"
          android:choiceMode="singleChoice"
          android:background="#FFFFFFFF"
          android:divider="@android:color/transparent"
          android:dividerHeight="0dp"/&gt;
  
  &lt;/android.support.v4.widget.DrawerLayout&gt;
  </code></pre>
