How to change the content of one picker based on the new selected value in another picker.

[Will Autio]

Hi SF Support person,

I have a Xamarin Forms app but in one section I require some specialized code for Android for managing Camera2. (similar code will be required for iOS later)

There are a few pickers that we use for recording details about the picture taken. Two of them are related. We have a picker for the Floor of the building (i.e. Basement, Ground, Upstairs - or whatever they decide to use). And then there is a picker for Room. The Room Picker gets populated depending on what Floor is picked.

I can do the initial populating fine. If control is passed in with Floor = Basement selected, then it also fills the Room picker with Rooms from the Basement.

But if I am already in the Android portion of the app and make a change to the selected Floor, say to Upstairs, then the corresponding rooms do not appear in the Room picker.

For both Floor and Room pickers I have set upArrayAdapter,DataAdapter and Spinner.Adapter.

Thoughts on what I may be missing? Would you have a sample that I could follow?

Thanks!
