Android_Picker_Screenshot

On Android, the Xamarin.Forms.Picker does not automatically resize horizontally to accommodate its ItemSource.

Reproduction:
- Download reproduction code from GitHub: https://github.com/brminnick/ChoppedPickerReproduction/tree/master
- Build/deploy to Android device
- The Picker will populate 2500ms after the app launches
- The Picker's contents will not be completely viewable

The Picker does automatically resize horizontally on iOS.

Note: A workaround is to set the Picker.WidthRequest to 50

var picker = new Picker{ WidthRequest = 50 };
Comment 3 Paul DiPietro [MSFT] 2017-06-22 17:49:00 UTC
Setting to confirmed; also checked against the latest 2.3.6 nightly build.
Comment 4 Brandon Minnick 2017-06-25 00:54:39 UTC
