android: increase width width of quotespan strip -

i using quotespan textview

spannablestring t1 = new spannablestring(html.fromhtml(myitems.get(position).gettest()));         t1.setspan(new quotespan(color.red), 0, t1.length(), spannable.span_paragraph);         txtview1.settext(t1); 

but displays very thin line on left of text, there way make line thicker looks better?
