use a selector , create a file xml in your drawable/ folder and name it bg_button.xml : 

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

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

</selector>

and then in your xml layout , define your button like this : 

<Button android:id="@+id/button"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@drawable/bg_button" />

NB : back_button_clicked and back_button_normal are drawables for the background of your button. the drawable back_button_clicked will be the background of your button when it will be clicked , and back_button_normal will be the background of your button in normal case.

  • you don't need to set the `onclickListener` and change the backgroundResource of your button programmatically , just add the selector ( `change_color.xml`) on your `drawable/` folder, and specify the `android:background="@drawable/change_color"` on your `Button `tag – Houcine Nov 27 '12 at 17:31
