title: Android-L CardView Visual Touch Feedback
body: <p>could anybody explain to me how to implement some of the visual touch feedback that was demonstrated at Google I/O 2014 within a CardView.</p>
  
  <p>Here is how I am using the CardView in XML, there is probably something small that I am missing, so I just wondered if anyone could help me?.</p>
  
  <pre><code>&lt;!-- A CardView --&gt;
  &lt;android.support.v7.widget.CardView
      xmlns:card_view="http://schemas.android.com/apk/res-auto"
      android:id="@+id/CardView_1"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginLeft="10dp"
      android:layout_marginRight="10dp"
      android:layout_marginTop="10dp" 
      card_view:cardCornerRadius="4dp"
      android:elevation="2dp"&gt;
  
      &lt;LinearLayout
          android:id="@+id/LinearLayout_1"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="horizontal"
          android:onClick="RunSomeMethod""&gt;
  
      &lt;!-- Main CardView Content In Here--&gt;
  
      &lt;/LinearLayout&gt; &lt;/android.support.v7.widget.CardView&gt;
  </code></pre>
