title: spannable on android for textView
body: <pre><code>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);

  </code></pre>
  
  <p>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?</p>
