title: Android using indexOf
body: <p>I have this, <code>tweet.title</code> is a string that is equals to <code>I love burgers.</code></p>
  
  <pre><code>        CharSequence i = tweet.title.indexOf(Integer.valueOf("I"));
  
          SpannableString WordtoSpan = new SpannableString(i);        
          WordtoSpan.setSpan(new ForegroundColorSpan(Color.RED), 0, 7, Spannable.SPAN_EXCLUSIVE_EXCLUSIVE);
  
          holder.txtTitle.setText(WordtoSpan);
  </code></pre>
  
  <p>Now I get this error from it <code>Type mismatch: cannot convert from int to CharSequence</code></p>
  
  <p>I wanna find the <code>I</code> in the string.</p>
