title: A better way to OnClick for EditText fields?
body: <p>I have an EditText field, suppose the user has already entered text into it. Then the user wants to come back to edit the text again: the feature I want for this EditText field is that if you select it after it already has text in it, it clears the text for you before you can type something new in. </p>
  
  <p>I tried using the EditText field's OnClick method, but this required that I select the EditText field, then click on it a second time, something that isn't obvious to anyone but me. How can I get the text to clear from the EditText field as soon as the user selects it?</p>
