, which changes the background
color of the lines to which the span is attached.
For example, an LineBackgroundSpan
can be used like this:
String text = "This is a multiline text. LineBackgroundSpan is applied here. This is a multiline text."; SpannableString string = new SpannableString(text); string.setSpan(new LineBackgroundSpan.Standard(Color.YELLOW), 26, 61, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
