  <p>what I did is when I put
   <code>android:background="@null"</code> for TextView is not working showing the whole view with blue color background.</p>
  
  <pre><code>&lt;LinearLayout
                  android:layout_width="wrap_content"
                  android:layout_height="match_parent"
                  android:layout_centerVertical="true"
                  android:background="@drawable/btn_selector"
                  android:clickable="true" &gt;
  
                  &lt;ImageView
                      android:id="@+id/back_arrow"
                      android:layout_width="wrap_content"
                      android:layout_height="match_parent"
                      android:src="@drawable/ic_ab_back_holo_dark" /&gt;
  
                  &lt;TextView
                      android:id="@+id/settings_title"
                      android:layout_width="wrap_content"
                      android:layout_height="match_parent"
                      android:layout_marginLeft="10dp"
                      android:background="@null" 
                      android:layout_toRightOf="@id/back_arrow"
                      android:gravity="center_vertical"
                      android:text="@string/settings_title"
                      android:textColor="@color/white"
                      android:textSize="22sp" /&gt;
              &lt;/LinearLayout&gt;
