  <?xml version="1.0" encoding="utf-8"?>

  <selector xmlns:android="http://schemas.android.com/apk/res/android">

      <item android:state_focused="true" android:state_pressed="false" android:drawable="@drawable/focused" />

      <item android:state_focused="true" android:state_pressed="true" android:drawable="@drawable/focusedpressed" />

      <item android:state_focused="false" android:state_pressed="true" android:drawable="@drawable/pressed" />

      <item android:drawable="@drawable/defaultbutton" />

  </selector>
