Best way to implement the selector is by using the xml instead of using programatic way as its more easy to implemnt with xml.

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

    </selector>

You can t achieve text size change with a state list drawable  To change text color and text size do this   Text color  To change the text color  you can create color state list resource  It will be a separate resource located in res color  directory  In layout xml you have to set it as the value for android textColor attribute  The color selector will then contain something like this    lt  xml version  1 0  encoding  utf-8   gt   lt selector xmlns android  http   schemas android com apk res android  gt       lt item android state pressed  true  android color   color text pressed    gt       lt item android color   color text normal    gt   lt  selector gt    Text size  You can t change the size of the text simply with resources  There s no  dimen selector   You have to do it in code  And there is no straightforward solution    Probably the easiest solution might be utilizing View onTouchListener   and handle the up and down events accordingly  Use something like this   view setOnTouchListener new OnTouchListener               Override         public boolean onTouch View v  MotionEvent event                switch  event getAction                  case MotionEvent ACTION DOWN                     change text size to the  pressed value                  return true              case MotionEvent ACTION UP                     change text size to the  normal value                  return true              default                  return false                                A different solution might be to extend the view and override the setPressed Boolean  method  The method is internally called when the change of the pressed state happens  Then change the size of the text accordingly in the method call  don t forget to call the super
