spannable on android for textView

Tweet o = tweets.get(position);

TextView tt = (TextView) v.findViewById(R.id.toptext);
//TextView bt = (TextView) v.findViewById(R.id.bottomtext);         

EditText bt =(EditText)findViewById(R.id.bottomtext);
bt.setText(o.author);
Spannable spn = (Spannable) bt.getText();
spn.setSpan(new StyleSpan(android.graphics.Typeface.BOLD_ITALIC)
, 0, 100, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);  

//bt.setText(o.author);    
tt.setText(o.content);

I’m setting twitter data in my Android application. I want to make the font bold and italic using Spannable but it does not work, giving an error. How can I do it?

Answer

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>"));
