Description Brandon Minnick 2017-06-16 02:33:51 UTC
Created attachment 22932 [details]

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

- 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 };

Setting to confirmed; also checked against the latest 2.3.6 nightly build.
Comment 4 Brandon Minnick 2017-06-25 00:54:39 UTC
