title: Set edittext field to be a password?
body: <pre><code>android:password="true"
  </code></pre>
  
  <p>This hides the letters (****) but not immediately! When I type the letters, it take a while to hide.</p>
  
  <p>For example, at the moment I type "a"; it shows ***a then it becomes ****. 
  How can I transform it immediately?</p>
