title: How to let TextView be able to scroll horizontally
body: <p>I know the <code>TextView</code> is embedded in a <code>ScrollView</code>. And if there is a fairly long <code>String</code><strong>(Which contains no <code>"\n"</code>)</strong></p>
  
  <p>The <code>TextView</code> will automatically do the line-wrap, according to the width of the <code>TextView</code>.</p>
  
  <p>If <code>TextView</code>'s height is short, then we are able to scroll it vertically. 
  How do you disable the auto line-wrap? Such that, if there are no "\n" encounters, it does not line wrap. Rather, it lets the user scroll horizontally to view the text.</p>
  
  <p>How can I implement this?</p>
