The RIGHT way     The following methods actually work   if you wish - using a theme By default a buttons color is android colorAccent  So  if you create a style like this      lt style name  Button White  parent  ThemeOverlay AppCompat  gt       lt item name  colorAccent  gt  android color white lt  item gt   lt  style gt    You can use it like this      lt Button     android layout width  wrap content      android layout height  wrap content      android theme   style Button White        gt    alternatively - using a tint You can simply add android backgroundTint for API Level 21 and higher  or app backgroundTint for API Level 7 and higher   For more information  see this blog   The problem with the accepted answer     If you replace the background with a color you will loose the effect of the button  and the color will be applied to the entire area of the button  It will not respect the padding  shadow  and corner radius

You can change the value in the XML like this   lt Button     android background  quot  FFFFFF quot           gt   Here  you can add any other color  from the resources or hex  Similarly  you can also change these values form the code like this  demoButton setBackgroundColor Color WHITE    Another easy way is to make a drawable  customize the corners and shape according to your preference and set the background color and stroke of the drawable  For eg  button background xml  lt  xml version  quot 1 0 quot  encoding  quot UTF-8 quot   gt   lt shape xmlns android  quot http   schemas android com apk res android quot  gt       lt stroke android width  quot 2dp quot  android color  quot  ff207d94 quot    gt       lt corners android radius  quot 5dp quot    gt       lt solid android color  quot  FFFFFF quot    gt   lt  shape gt   And then set this shape as the background of your button   lt Button     android background  quot  drawable button background xml quot           gt   Hope this helps  good luck
