When my screen is too small then my listview does not want to scroll. If my screen is not too small then listview does scroll. Can someone help me pls?

回答1:

Never stack a ListView inside a ScrollView as both implement scrolling on Android at least.

回答2:

Xamarin.Forms.ScrollView Class documentation says:

Application developers should not nest one ScrollView within another. Additionally, they should refrain from nesting them other elements that can scroll, such as WebView.

ListView.ScrollTo Method Scrolls the ListView to the item.
