Button Background Selector

I try to switch the background of Buttons if they are pressed. I build a Selector like the answer suggested here: Standard Android Button with a different color

Finally I want to put GradientDrawables inside, but for debugging purposes I just set a color, to che开发者_StackOverflowck if it works. Here is my Selector

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

  <item android:drawable="@color/red"/>
  <item 
    android:state_focused="true"
    android:drawable="@color/white"/>
   <item 
    android:state_pressed="true"
    android:drawable="@color/white"/>
</selector>

Unfortunatly this doesn't work. I set the Selector as Button background and only see them in red color. What Am I doing wrong (Build Target 2.1)

put this at the end

item android:drawable="@color/red"

i mean as the third option, it will work. android checks the xml conditions from the start, the first tag doesn't have any condition, so it will always pick red, so you have put conditions first and then the default one.

here is the code I use, and it works really well.

 <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/button_clicked"
        android:state_pressed="true" android:state_enabled="true" />

    <item android:drawable="@drawable/button" android:state_enabled="true" />
    </selector>

here I use two images I made using photoshop as a background

the first is button_clicked and the second is button

copy it and change use your own resources.

hope I could help :)
