title: Android GridView ItemClikListneter issue
body: <p>I created a <code>GridView</code> with item.xml that include image inside the <code>LinearLayout</code>.</p>
  
  <p>Gridview code:</p>
  
  <pre><code>&lt;GridView
              android:id="@+id/gridView"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
              android:clickable="true"
              android:columnWidth="150dip"
              android:gravity="center"
              android:horizontalSpacing="10dip"
              android:numColumns="auto_fit"
              android:stretchMode="columnWidth"
              android:verticalSpacing="15dip" &gt;
          &lt;/GridView&gt;
  </code></pre>
  
  <p>item.xml code:</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:id="@+id/itemLayout"
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@drawable/selector"
  android:clickable="true"
  android:gravity="center_horizontal"
  android:orientation="vertical" &gt;
  
  &lt;ImageView
      android:id="@+id/itemIcon"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:clickable="true"
      android:scaleType="matrix"
      &gt;
  &lt;/ImageView&gt;   
  </code></pre>
  
  <p></p>
  
  <p>Then I added selector.xml for <code>LinearLayout</code> background to avoid showing selected area when click on item.</p>
  
  <p>selector.xml code: </p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  </code></pre>
  
  <p></p>
  
  <pre><code>&lt;item android:drawable="@android:color/transparent" android:state_enabled="true" android:state_pressed="true"/&gt;
  &lt;item android:drawable="@android:color/transparent" android:state_enabled="true" android:state_focused="true"/&gt;
  &lt;item android:drawable="@android:color/transparent" android:state_enabled="true"/&gt;
  </code></pre>
  
  <p></p>
  
  <p>After adding <code>android:clickable="true"</code> to the item.xml <code>LinearLayout</code>, <code>GridView</code> <code>ItemClickListner</code> does not work.Otherwise it works but does not apply selector.xml effect to the <code>LinearLayout</code>.I want to apply selector.xml effect for the <code>LinearLayout</code> and works <code>ItemClickListner</code> also.</p>
  
  <p>Pls help me to fix this issue.Thanks.</p>
