title: How do I select all text when clicking on a EditText view?
body: <p>so I tried android:selectAllOnFocus and of course I'm using android:hint.
  The app loads, requestFocus triggers and the full text is selected. </p>
  
  <p>The problem is that when I click in the EditText the selection is lost. </p>
  
  <p>I've already read:
