Xamarin Forms ListView 元素被禁用

Question

In my app I use Shell tabs . One of the tab is ContentPage containing ListView.

When I click on any of the elements of ListView I am navigating to another View, and after navigation back ListView elements are disabled (see images in the bottom links).

How can I fix it?

Checked facts:

1. The bug only occurs on iOS , the application works correctly on Android
2. ListView's Selected element is null
3. The bug is not related to passing a reference to an element of ListView's ObservableCollection

I have escaping bug scenario, but it is not a problem salvation:

When app initialized click to another tab and return to problem tab back.

Answer 1

I change the ListView to the CollectionView and It's Works!

Unfortunately I will have to visualize the TextCell element entirely on my own.

Thanks everybody for comments.
