pls post LogCat output with the exception. Most likely you're trying to apply the span beyond the text end - use actual length instead of 100 — Asahi, Feb 12 '13 at 19:53

I want to make the font bold and ıtalic with spannable

for this u will need to make o.content text as SpannableString then set it to TextView as :

SpannableString spannablecontent=new SpannableString(o.content.toString());
spannablecontent.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC), 
                         0,spannablecontent.length(), 0);
// set Text here
tt.setText(spannablecontent);

EDIT : you can also use Html.fromHtml for making text Bold and Italic in textview as :

tt.setText(Html.fromHtml("<strong><em>"+o.content+"</em></strong>"));

The easy way to create a spannable text bold and italic to set into your TextView is using the method Html.fromHtml():

and using the html elements <b> and <i>

myTextView.setText(Html.fromHtml("<b><i>my text bold and italic!</i></b>"));

or the html elements <strong> and <em>

   myTextView.setText(Html.fromHtml("<strong><em>my text bold and italic!</em></strong>"));

SpannableString hint = new SpannableString(o.content.toString());

Font size

hint.setSpan(new RelativeSizeSpan(0.9f), 0, hint.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);

Font family

hint.setSpan(new TypefaceSpan("sans-serif"), 0, hint.length(), Spanned.SPAN_INCLUSIVE_INCLUSIVE);

italic

hint.setSpan(new StyleSpan(Typeface.ITALIC), 0, s.length(), 0);

color

hint.setSpan(new ForegroundColorSpan(Color.GRAY), 0, hint.length(), 0);

bold

hint.setSpan(new StyleSpan(Typeface.BOLD), 0, hint.length(), 0);
