conclusion

RadioButton and Check@R_ 762_ 2419 @ are commonly used widgets in Android apps. They are derived from the compoundbutton and allow users to set the background and button styles by themselves. However, sometimes we just want to simply set a stateful background and hide its default style. However, when we call setbuttondrrawable (null) or setbuttondrrawable (0), we find that it has no effect at all. Originally, the code implementation of setbuttondrrawable of composundbutton shields the drawable with null or resid 0, forcing us to pass in a valid drawable object.

At this point, transparent colors can come in handy:

button.setButtonDrawable(new ColorDrawable(Color.TRANSPARENT));
