Making part of a string bold in textview

Question

Why is the following code not working? It works in a Toast but not in a TextView. boldName doesn't show up as bold when I run my program but it does show up as bold when I set it to a Toast. Does anyone have any other solutions?

String boldName = "<b>" + name + "</b>";
Spanned conBold = Html.fromHtml(boldName);
chosen_contact.setText("You have chosen " + conBold + " as your contact.");

I'm honestly not sure why exactly TextViews act the way they do where you can set it all bold as you are doing, but only if they entire TextView is bold, yet you can't if only part of it is bold and there are other Strings in there.

However, this code will work for you:

// a SpannableStringBuilder containing text to display
SpannableStringBuilder sb = new SpannableStringBuilder("You have chosen " + name + " as your contact.");

// create a bold StyleSpan to be used on the SpannableStringBuilder
StyleSpan b = new StyleSpan(android.graphics.Typeface.BOLD); // Span to make text bold

// set only the name part of the SpannableStringBuilder to be bold --> 16, 16 + name.length()
sb.setSpan(b, 16, 16 + name.length(), Spannable.SPAN_INCLUSIVE_INCLUSIVE); // make first 4 characters Bold

chosen_contact.setText(sb); // set the TextView to be the SpannableStringBuilder
