android set button background programmatically
android, button
Solution
`R.color.red` is an ID (which is also an `int`), but is not a color.
Use one of the following instead:
// If you're in an activity:
Button11.setBackgroundColor(getResources().getColor(R.color.red));
// OR, if you're not:
Button11.setBackgroundColor(Button11.getContext().getResources().getColor(R.color.red));
Or, alternatively:
Button11.setBackgroundColor(Color.RED); // From android.graphics.Color
Or, for more pro skills:
Button11.setBackgroundColor(0xFFFF0000); // 0xAARRGGBB
Problem
I would like to know how to set the button color programatically? I have coded the following but fails: ``` Button11.setBackgroundColor(R.color.red); ``` Thanks!!
