java - Apply styles to text in a string Android -


i'm trying create string spannablestring apply colors , bold text.

spannable wordtospan = new spannablestring("salida de la capilla de maría auxiliadora\n00:00\nmarquesa de sales\n00:00\nespíritu santo\n00:00\nsagasta\n00:00\npza. meneses\n00:00\npozo nuevo\n00:00\npza. ayuntamiento\n00:00\nsan miguel\n00:00\nestación de penitencia, iglesia san miguel\n00:00\nÁnimas\n00:00\nmariano hernández\n00:00\neduardo dato\n00:00\nrojas marcos\n00:00\npza. meneses\n00:00\ncarrera\n00:00\ncalzadilla\n00:00\ngregorio maría ferro\n00:00\nmaría auxiliadora\n00:00\nmarquesa de sales\n00:00\nentrada al templo\n00:00\n");  tv.settext(wordtospan);

to speed work trying create condition this:

if(wordtospan.tostring().contains(":")){ // found text string ":" (00:00)  wordtospan.setspan(new foregroundcolorspan(color.rgb(140, 117, 189)), 42, 47,  spannable.span_exclusive_exclusive); wordtospan.setspan(new stylespan(typeface.bold), 42,47, 47); }else{ //not found ":" }

i implement bold text , color string 00:00. know quick , easy way? not go telling words words fill 00:00?

regards!

find index of "00:00" , , set start index of span , , end index length of "00:00"

    spannable wordtospan = new spannablestring("salida de la capilla de maría auxiliadora\n00:00\nmarquesa de sales\n00:00\nespíritu santo\n00:00\nsagasta\n00:00\npza. meneses\n00:00\npozo nuevo\n00:00\npza. ayuntamiento\n00:00\nsan miguel\n00:00\nestación de penitencia, iglesia san miguel\n00:00\nÁnimas\n00:00\nmariano hernández\n00:00\neduardo dato\n00:00\nrojas marcos\n00:00\npza. meneses\n00:00\ncarrera\n00:00\ncalzadilla\n00:00\ngregorio maría ferro\n00:00\nmaría auxiliadora\n00:00\nmarquesa de sales\n00:00\nentrada al templo\n00:00\n");      string search = new string("00:00");     int length = search.length();     string input = wordtospan.tostring();     int startindex = input.indexof(search);     while(startindex > length)     {         wordtospan.setspan(new foregroundcolorspan(color.rgb(140, 117, 189)), startindex, startindex + length,                 spannable.span_exclusive_exclusive);         wordtospan.setspan(new stylespan(typeface.bold), startindex, startindex + length, spannable.span_exclusive_exclusive);         startindex = input.indexof(search, startindex + length);     }

you have loop throughout string index
