title: State_Selected is not working although state_pressed works
body: <p>i have a problem. First check my code:</p>
  
  <pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
      &lt;item android:state_selected="true" android:color="@color/clickedtext" /&gt;
      &lt;item android:state_pressed="true" android:color="@color/clickedtext" /&gt;
      &lt;item  android:color="@color/defaulttext" /&gt;
  &lt;/selector&gt;
  </code></pre>
  
  <p>Here, defaulttext color appears at default state. When i clicked, text color in the listitem changes. But color of the text does not change when an item selected.</p>
  
  <p>I tried some stuff, but i cannot handle this problem.
  What should i do ?</p>
