Android Button ==> Set highlighted image ???

Question

How can i set the button to show a different image after it's been tapped? Either a different image, or maybe some kind of highlighting that shows the button was tapped/

Thanks

When you define a ImageButton on your layout you can set different images for different states: normal, selected and pressed; using a state drawable, defined in xml, like this (btn_state.xml, under res/drawable directory):

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
        <item android:state_pressed="true" 
            android:drawable="@drawable/btn_pressed" />
        <item android:state_focused="true"
            android:drawable="@drawable/btn_selected" />
        <item
            android:drawable="@drawable/btn_normal" />
    </selector>

Of course, you need those btn_normal, selected and pressed as PNGs in your drawables directory.

On your <ImageButton> then you set that resource name as the background:

<ImageButton
    ...
    android:background="@drawable/btn_state"
    ... />
