Step to reproduce:
1. Use setError on a TextView or EditView
2. See the error Tooltip show up.
3. Look for how to style that tooltip
4. end up here: http://stackoverflow.com/questions/14413575/how-to-write-style-to-error-text-of-edittext-in-android
5. don't liking the library in the accepted solution
6. dig in the code of TextView a little
7. realize you can't really create a customized version of the tooltip that works like the default one

Expected result:
1. you can use an attribute in theme to change the tooltip style / background
2. you can also change it directly on the TextView with an attribute

Android SDK version: Any
Devices: Any


I think that a custom widget that works like the default one can't be achieved.
Assuming I'm extending an EditText with a custom widget, this ares the steps I should take and how to do them

- override setError methods with your own
- create your custom PopupWindow
- showing the tooltip only when the view is focused: add onFocusChanged listener and operate there
- hiding the error when the user change the text: add TextWatcher listener and clear the error when it change -- the framework does fancy things here and apparently I do not receive ALL the text changes notifications from the TextWatcher
- override methods in the edit text (setFrame?) to reposition the error tooltip as needed
- show an icon: override setCompountDrawable and manually handle them for being able to draw your own icon in place of the right drawable
- error being set before the view is attached: keep a flag in your custom view to know that you should show the tooltip when attached to the window
- scroll to the (first) view for which setError has been called: I've no idea on how to achieve this right now

Request:
if you fix this please provide a Compat version of the TextView/EditText so that we can make use of it in previous versions too.

Secondary Request:
please provide instruction on how to properly create our custom EditText with a custom popup style
