title: Override Android-L CardView state_pressed for Older versions of Android
body: <p>In the latest Android SDK we now have the new CardView, I have replaced my old CustomCardView with the new version, but when running with this on older versions of Android I see that the <code>state_pressed</code> &amp; <code>state_focused</code> are ugly squares which show up above the CardView...</p>
  
  <p>does anyone know how I could emulate the following in the new CardView but only when using older versions of Android?</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"
      android:enterFadeDuration="150"
      android:exitFadeDuration="150" &gt;
  
      &lt;item android:state_pressed="true"
            android:drawable="@drawable/card_on_press"/&gt;
      &lt;item android:state_focused="true" android:state_enabled="true"
            android:drawable="@drawable/card_on_focus"/&gt;
      &lt;item android:state_enabled="true"
            android:drawable="@drawable/card_default"/&gt;
      &lt;item android:state_enabled="false"
            android:drawable="@drawable/card_on_press"/&gt;
  
  &lt;/selector&gt;
  </code></pre>
  
  <p>And for those of you interested here is the CardView that I am using now:</p>
  
  <pre><code>&lt;android.support.v7.widget.CardView
      xmlns:card_view="http://schemas.android.com/apk/res-auto"
      android:id="@+id/CardView"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_marginLeft="10dp"
      android:layout_marginRight="10dp"
      android:layout_marginTop="10dp"
      android:foreground="?android:attr/selectableItemBackground"
      android:onClick="RunSomeMethod"
      card_view:cardCornerRadius="4dp"
      android:focusable="true"
      android:elevation="2dp"&gt;
  
      &lt;LinearLayout
          android:id="@+id/LinearLayout"
          android:layout_width="match_parent"
          android:layout_height="wrap_content"
          android:orientation="horizontal"
          android:focusable="false"
          android:visibility="visible"&gt;
  
      &lt;/LinearLayout&gt;
  &lt;/android.support.v7.widget.CardView&gt;
  </code></pre>
