We can use attribute android background in Button xml like below  android background  quot  android attr selectableItemBackground quot   Or we can use style style  quot  android attr borderlessButtonStyle quot  for transparent and shadow less background

Selectors work only for drawables  not styles  Reference    First  to make the button background transparent use the following attribute as this will not affect the material design animations   style   attr buttonBarButtonStyle    There are many ways to style your button  Check out this tutorial   Second  to make the text bold on pressed  use this java code   btn setOnTouchListener new View OnTouchListener          Override     public boolean onTouch View v  MotionEvent event             switch  event getAction                     When the user clicks the Button             case MotionEvent ACTION DOWN                  btn setTypeface Typeface DEFAULT BOLD                   break                  When the user releases the Button             case MotionEvent ACTION UP                  btn setTypeface Typeface DEFAULT                   break                    return false

You apply the background color as transparent light gray  when you click the button   ButtonName setOnClickListener     In the above method you set the background color of the button

To make a background transparent  just do android background   android color transparent    However  your problem seems to be a bit deeper  as you re using selectors in a really weird way  The way you re using it seems wrong  although if it actually works  you should be putting the background image in the style as an  lt item  gt    Take a closer look at how styles are used in the Android source  While they don t change the text styling upon clicking buttons  there are a lot of good ideas on how to accomplish your goals there
