title: How to create a empty bullet paragraph by BulletSpan?
body: <p>I wanted to create a empty bullet paragraph, but it didn't work.
  This is my code:</p>
  
  <pre><code>EditText contentET = (EditText) findViewById(R.id.content);
  contentET.setText("abc\n123\n");
  Spannable s = contentET.getText();
  s.setSpan(new BulletSpan(), 0, 1, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
  s.setSpan(new BulletSpan(), 4, 5, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
  s.setSpan(new BulletSpan(), 7, 8, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
  contentET.setText(s);
  </code></pre>
  
  <p>When i ran above code, it seemed this line doesn't work</p>
  
  <pre><code>s.setSpan(new BulletSpan(), 7, 8, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
  </code></pre>
  
  <p>Instead, i saw an unexpected white space after "123".
  Anyone knows how to create a empty bullet paragraph by BulletSpan?
  Thanks!</p>
