title: How I can create animation like PopupWindow showAsDropDown?
body: <p>Is there any way to implement Popup Window's <code>showAsDropDown</code> function animation? For example, a way to show Dialog with this drop down animation?</p>
  
  <p>I can't use PopupWindow because app crashes when I set errors via <code>EditText.setError();</code> - it is known issue and it is still not fixed.</p>
