Solution 1

//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

@sandiparmal save that xml in you drawable folder and try it as android:background="@drawable/button_bg".

[Padma Kumar]

@sandiparmal this error is not related to this code. its different error in you app.

[Shaista Naaz]

@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"

[Rajat Anantharam]

<item> tag requires a 'drawable' attribute or child tag defining a drawable. This piece of code will not work

[Padma Kumar]

@RajatAnantharam yes you need to report to google soon developer.android.com/guide/topics/resources/…

[Rajat Anantharam]

Its an easy fix. Define shape drawables with solid colors of choice for each states. I am in no hurry to report to Google :)

[pa1pal]

android:color is not a valid command in <selector> What I did to avoid crashing was create a color.xml file in values and define color in between <color name="gray">#808080</color> and give link to that in button_bg.xml .

[Padma Kumar]

@pa1pal might be you forgot to add inside it in <item>. see the 3rd comments from bottom.

Why will it work? Add some extra details to make it a great answer.
