title: Android - Get cursor's position at the current line.
body: <p>I have an EditText, and I want to display cursor info for user.
  But I can't get cursor position at the line which user is editing.
  For ex.</p>
  
  <pre><code>`The quick b|rown fox...` - Cursor @ line 0, symbol 13
  `StackOverflow rule|s!` - Cursor @ line 1, symbol 20
  </code></pre>
