  <p>If Im correct we need to make framelayout backgrund totally transparent . But no effect taking place on doing it.</p>
  
  <p>Thanks for all your reponses , but none ofthem seems to be working so far. </p>
  
  <p>To clarify further , I need to make the background below the listview to be transparent.</p>
  
  <p>That is, when the drawer is opened completely .There is a partial screen from the below  activity that is visible. It shows as blurred greyed out with some text visible. I need that to be perfectly visible. </p>
  
  <p>Do I need to change some themes in activity?</p>
  
  <p>The following is the complete layout xml</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

  &lt;RelativeLayout

      &lt;Button

          android:textColor="@color/white" /&gt;
  &lt;/RelativeLayout&gt;
  
  &lt;android.support.v4.widget.DrawerLayout
      xmlns:android="http://schemas.android.com/apk/res/android"

          android:layout_width="match_parent"
          android:layout_height="match_parent" /&gt;
  
      &lt;!--
       android:layout_gravity="start" tells DrawerLayout to treat
       this as a sliding drawer on the left side for left-to-right
       languages and on the right side for right-to-left languages.
       The drawer is given a fixed width in dp and extends the full height of
       the container. A solid background is used for contrast
       with the content view.
      --&gt;
  
      &lt;ListView
          android:id="@+id/left_drawer"
          android:layout_width="240dp"
          android:layout_height="match_parent"
          android:layout_gravity="start"
          android:background="@color/logoutBtnBlue"
          android:choiceMode="singleChoice"
          android:divider="@android:color/white"
          android:dividerHeight="1dp" /&gt;
  &lt;/android.support.v4.widget.DrawerLayout&gt;
