I read a couple of posts but none of them had the working solution.
Once you do
button.setBackgroundColor(0x00000000); How do you revert the button's background color back to default color?

By default each activity in Android has a white background. To change the background color, first add a new color definition to the colors.
The color BLUE is reserved for functions of urgent significance. Reset push-buttons must be BLUE, WHITE, GREY or BLACK. If these are also used as STOP/OFF buttons, the colors WHITE, GREY or BLACK are preferred, preferably BLACK. GREEN must not be used.
By default, a button has a white background and black text. Using the CSS background-color property, we can change a button's background color.
use:
btn.setBackgroundResource(android.R.drawable.btn_default); If the background color was set using
btn.getBackground().setColorFilter(Color.RED, PorterDuff.Mode.MULTIPLY); it can be reset using:
btn.getBackground().clearColorFilter(); In contrast to button.setBackgroundColor() setting the color this way preserves the button's shape.
