Answer 1

You can directly set the image of button in different conditions like this:-

((ImageButton)shackButton).setImageResource(R.drawable.<imageid>);

You can do it without creating any other resource file.

Answer 2

change your xml to this

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/shack1000green" android:state_focused="true" android:state_pressed="true"/>
    <item android:drawable="@drawable/shack1000grey" android:state_focused="false" android:state_pressed="true"/>
    <item android:drawable="@drawable/shack1000" android:state_focused="false" android:state_pressed="false"/>
    </selector>
