//XML file saved at res/drawable/button_bg.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_pressed="true"
          android:color="#ffff0000"/> <!-- pressed -->
    <item android:state_focused="true"
          android:color="#ff0000ff"/> <!-- focused -->
    <item android:color="#ff000000"/> <!-- default -->
</selector>

//This layout XML will apply the color list to a View:

<Button android:textSize="15px"
      android:id="@+id/button9" 
      android:gravity="center|bottom" 
      android:textColor="@color/myWhiteColor" 
      android:drawableTop="@drawable/math"
      android:text="@string/HomePage_Math" 
      android:background="@drawable/button_bg" 
      android:layout_width="54dp" 
      android:layout_height="wrap_content" ></Button>

It show error "tts application has stop unexpectedly"...Not working – Sandip Armal Patil Mar 13 '12 at 14:05
@sandiparmal save that xml in you drawable folder and try it as android:background="@drawable/button_bg". – Padma Kumar Mar 13 '12 at 14:07
@sandiparmal this error is not related to this code. its different error in you app. – Padma Kumar Mar 13 '12 at 15:35

@SandipArmalPatil if you use drawable instead of color codes in the button_bg xml then you will not get this error "application has stop unexpectedly" – Shaista Naaz Sep 16 '12 at 20:02

tag requires a 'drawable' attribute or child tag defining a drawable. This piece of code will not work – Rajat Anantharam Dec 11 '13 at 13:52
@RajatAnantharam yes you need to report to google soon http://developer.android.com/guide/topics/resources/color-list-resource.html – Padma Kumar Dec 11 '13 at 14:09
Its an easy fix. Define shape drawables with solid colors of choice for each states. I am in no hurry to report to Google :) – Rajat Anantharam Dec 11 '13 at 14:29
android:color is not a valid command in What I did to avoid crashing was create a color.xml file in values and define color in between #808080 and give link to that in button_bg.xml . – pa1pal Mar 20 '14 at 10:51
@pa1pal might be you forgot to add inside it in . see the 3rd comments from bottom. – Padma Kumar Mar 20 '14 at 12:01

<?xml version="1.0" encoding="utf-8"?>

    <item android:state_focused="true" android:drawable="@android:color/holo_green_dark" />
