[英]Get index number of item at the top of a Listview OnDisappear in Xamarin Forms
Is it possible to get the index number of a listview cell that is on the top of the ListView when OnDisappear? 当OnDisappear出现时,是否可以获得列表视图顶部的列表视图单元格的索引号?
I am trying to store the position of the listview when a user tabs to clicks a modal, and restore it later OnAppear. 我试图在用户使用Tab键单击模式时存储listview的位置,然后在OnAppear上将其还原。
I would use ItemAppearing event 我将使用ItemAppearing事件
var listView = new ListView { ... };
listView.ItemAppearing += async (sender, e) =>
{
// get index of e.Item + add count of items available at visual
};
