<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/btn_button_focus" />
    <item android:state_pressed="true" android:drawable="@drawable/btn_button_pressed" />
    <item android:drawable="@drawable/btn_button_normal" />
</selector>

Answer 1

you are right. But you didnt mentioned when the state is not pressed or not focused and not selected then what you will do?

Try this:
make a styles.xml file in you res.values folder
and add it.

 <style name="styleNormalButton">
        <item name="android:background">@drawable/backgroundbutton</item>
    </style>

consider the @drawable/backgroundbutton.xml is your selector file and add the below code in that.

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@drawable/btn_button_focus" />
    <item android:state_pressed="true" android:drawable="@drawable/btn_button_pressed"/>

    <item android:drawable="@drawable/btn_default_pressed_holo_dark"
      android:state_enabled="false" />
    <item android:drawable="@drawable/btn_button_normal" />
</selector>

and finally into your layou file.
set the background of the button to style/styleNormalButton

hope this will help you
