Method: setSpanColor
public Spanned setSpanColor(String string, int color){
SpannableStringBuilder builder = new SpannableStringBuilder();
SpannableString ss = new SpannableString(string);
ss.setSpan(new ForegroundColorSpan(color), 0, string.length(), 0);
builder.append(ss);
return ss;
}
Usage:
String a = getString(R.string.string1);
String b = getString(R.string.string2);
Spanned color1 = setSpanColor(a,Color.CYAN);
Spanned color2 = setSpanColor(b,Color.RED);
Spanned mixedColor = TextUtils.concat(color1, " ", color2);
// Now we use `mixedColor`
