How to change the color of a button?

Question

I\'m new to android programming. How do I change the color of a button?

Answer 1

Through Programming:

btn.setBackgroundColor(getResources().getColor(R.color.colorOffWhite));

and your colors.xml must contain...

<?xml version="1.0" encoding="utf-8"?>
<resources>
 <color name="colorOffWhite">#80ffffff</color>
</resources>

Answer 2

If you are trying to set the background as some other resource file in your drawable folder, say, a custom-button.xml, then try this:

button_name.setBackgroundResource(R.drawable.custom_button_file_name);

eg. Say, you have a custom-button.xml file. Then,

button_name.setBackgroundResource(R.drawable.custom_button);

Will set the button background as the custom-button.xml file.
