android - How to change some words of a string to BOLD? -

this string getting web using json api in code:

string content = "<strong><em>india world’s hub child sex trafficking</em> </strong></p>\n<p style=\"text-align: center;\"><strong><em>nearly 40,000 children abducted every year… </em></strong></p>\n<p style=\"text-align: center;\"><strong<em> every8 minutes girl child goes missing in india!</em></strong></p>\n<p><strong>priti pathak</strong></p>\n<p>meet shivani shivaji roy, senior inspector, crime branch, mumbai police, sets out confront mastermind behind child trafficking mafia," 

in string whatever text in

"<strong><em> text </em></strong>" 

i want display bold. above string

<strong><em>india world’s hub child sex trafficking</em></strong>  

will displayed india world’s hub child sex trafficking . should happen entire string. code using:

 int startindex = content.indexof("<strong><em>")+13;  // 13 because <strong><em> has 13 characters          string substring = content.substring(startindex, startindex+200);          int subendindex = substring.indexof("</em></strong>");          int endindex = startindex + subendindex;  spannablestring s = new spannablestring(content); s.setspan(new stylespan(android.graphics.typeface.bold), startindex, endindex, 0); textview.settext(s, buffertype.spannable );  

this code working setting bold text text whichever first within strong tag , not rest. because setting bold text first tag.

how should startindex, endindex of "strong tags" , can set

s.setspan(new stylespan(android.graphics.typeface.bold), startindex, endindex, 0); 

to texts , number of times have set span.

i though of using regex dont know how indexes using it. nice. thankyou !

the easier way use html class:

s = html.fromhtml(content); 

see documentation details.
