listview android studio doesnt reach end of screen

This is perhaps the simplest solution if all you want to know is if the user has ever scrolled to the end. If we keep track of what item is the last in the collection, we can watch for an ItemAppearing event to say that it is being rendered. So we can implement a limited version of this using ItemAppearing. Additionally it fires during virtualization, which may not correspond directly with removal from the screen depending on the platform virtualization technique used. It is not guaranteed to fire for all visible items when the List is removed from the screen. This method is for virtualization usage only.

Unfortunately, as noted in the documentation for ItemDisappearing: Start with adding handlers for ListView.ItemAppearing and ListView.ItemDisappearing, do some bookkeeping with the contents of the collection, and it should work. The first question might be, is this possible strictly using Xamarin.Forms classes, without using any custom renderers? The answer, at least as of today, is no, though it seems like it ought to. We’ll add this to our class that inherits from ListView: public static readonly BindableProperty AtEndOfListProperty =īindableProperty.Create(nameof(AtEndOfList), typeof(bool), typeof(MyListView), false) Let’s start with what we want to see on the Forms side of our app.

My colleague Lazareena and I recently collaborated on a solution for this, and here’s what we came up with. When the user reaches the end, the app can automatically download more entries. Building on a previous post about seeing how a user interacts with a ListView in Xamarin.Forms, the next question is, “Has the user scrolled to the end?” This can be useful, for instance, if the user is scrolling through a long feed of data, and only a portion is returned at a time.
