android - How do I change the tint of an ImageButton on focus/press

Question

I have an ImageButton in my app and I need to change the tint of the image when the button is pressed/focused. I have the ImageButton set to get its src from an XML file which as follows:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- pressed -->
    <item 
        android:state_pressed="true"
        android:tint="@color/black"
        android:drawable="@drawable/search"
        />

    <!-- focused -->
    <item 
        android:state_focused="true"
        android:tint="@color/black"
        android:drawable="@drawable/search"
        />

    <!-- default -->
    <item
        android:tint="@null"
        android:drawable="@drawable/search"
        />

</selector>

However the tint isn't applied when the ImageButton is pressed or focused - the image just displays as normal. The color black is defined as #000000 as always. Any ideas?

You can change the tint, quite easily in code via:

ImageButton button = (ImageButton) this.findViewById(R.id.button_i_want_to_modify);
button.setColorFilter(Color.argb(255, 255, 255, 255)); // White Tint

Hope it helps.
