Most efficient way for Dynamic Text Color Change in TextView

Question

I want to change color of parts of a text several times with a timer.

Simplest way is this:

SpannableStringBuilder ssb = new SpannableStringBuilder(m         


        

Answer 1

execute below code once:

SpannableStringBuilder ssb = new SpannableStringBuilder(mainText);
ForegroundColorSpan span = new ForegroundColorSpan(Color.BLUE);

and every time you want to change span do this:

ssb.clearSpans()
ssb.setSpan(span, start, end, 0);
tv.setText(ssb);
