Android: set background color of radiobutton text programatically

When i try to change background color of radio button text programatically like this:

rb.setBackgroundResource(R.drawable.mycustombackground);

The background covers both the button and the text.
I only want to change the background color of the text part (not the radio button).

How to achieve that?

Solution

  • Ok, lets see if it works:

    Spannable span = new SpannableStringBuilder(rb.getText().toString());
span.setSpan(new BackgroundColorSpan(Color.RED), 0, rb.getText().toString().length(), SpannableStringBuilder.SPAN_INCLUSIVE_INCLUSIVE);
rb.setText(span);

    Replace Color.RED with whichever color you want. Don't forget you have to grab it from the resources if you want it. I don't think it works with drawables.
