i tried modify code,but didn't got expected result

public void setcompulsoryasterisk(){          txt_name="name : ";         string colored="*";         spannablestringbuilder strbuilder=new spannablestringbuilder();         strbuilder.append(txt_name);         int start=strbuilder.length();         strbuilder.append(colored);         int end=strbuilder.length();         strbuilder.setspan(new foregroundcolorspan(color.red), start, end, spannable.span_exclusive_exclusive);         txtname.settext(strbuilder);     } 

string txt_name="name "; string colored="*"; string colon = " : "; 

after append string colored, append string colon after it. voila.
