title: How to avoid parent view/viewgroup animation for click events in GridView's cell
body: <p>I am using a TextView inside a LinearLayout for GridView's cell. The TextView is supposed to animate(like button) in pressed state, for which I am using drawable property. Everything is fine apart from the fact that the rectangular Grid cell gets little darken even outside circle, which i wasn't expecting. This is shown in the image below.</p>

  <p>Question: What is it called and How to avoid it?</p>
  
  <p>The XML resources are as follows:</p>
  
  <ul>
  <li><p>Layout used for grid cell</p>
  
  <p>
  </p>
  
  <pre><code>&lt;TextView
      android:layout_width="fill_parent"
      android:layout_height="fill_parent"

      android:background="@drawable/circularbutton_selector"
      android:layout_margin="0dp"
      android:gravity="center_horizontal|center_vertical"
      android:textSize="40dp"
      android:text="-"
      android:layout_gravity="center_horizontal|center_vertical"
      android:elevation="5dp"
      /&gt;
  </code></pre>
  
  <p></p></li>
  <li><p>circularbutton_selector.xml</p>
  
  <p>
  </p>
  
  <pre><code>&lt;item android:state_selected="true"
      android:drawable="@drawable/circularbutton_selected"/&gt;
  &lt;item android:state_pressed="true"

  &lt;item android:drawable="@drawable/circularbutton"/&gt;
  </code></pre>
  
  <p></p></li>
  <li><p>circularbutton_pressed</p>
