Infinite scrolling CarouselView #548

Closed wegascee closed 4 years ago

wegascee commented 5 years ago

I'm trying to implement a infinite scrolling carousel view. But that doesn't quite work well. First, the documentation imho is wrong:

Render one page at a time, no swiping, move back and fort programmatically:

myCarousel.ItemsSource = new List<int> { 0 }; // only one item in ItemsSource

To move forward:

public async void OnNext(object sender, TappedEventArgs e)
{
  if (myCarousel.ItemsSource[0] < 4)
  {
      myCarousel.ItemsSource.Add(myCarousel.ItemsSource[0] + 1);
      myCarousel.ItemsSource.RemoveAt(0);
  }
}

To move backward:

public async void OnPrev(object sender, TappedEventArgs e)
{
  if (myCarousel.ItemsSource[0] > 0)
  {
      myCarousel.ItemsSource = new List<int>() { myCarousel.ItemsSource[0] - 1,  myCarousel.ItemsSource[0] };
      await Task.Delay(100);
      myCarousel.AnimateTransition = false;
      myCarousel.Position = 1;
      myCarousel.AnimateTransition = true;
      myCarousel.ItemsSource.RemoveAt(1);
  }
}

I can't use ItemSource and call the methods Add() or RemoveAt() on it. You can only do this on your enumaration object on your model. Furthermore, I don't get why you use Task.Delay(100);, AnimateTransition and Position. But the issue more is, that if I add or remove an item from my model, the position in the carousel view changes. This could be solved by setting the position I believe.

But my main issue currently is, that I get the following error on inserting/removing items in the carousel view:

Foundation.MonoTouchException: Objective-C exception thrown. Name: NSInternalInconsistencyException Reason: Invalid parameter not satisfying: [views count] == 3

I don't fully understand why this happens. Sometimes it doesn't happens, but now it always happens. Here is the full output from the console:

I have attached the sample project so that you can have a look at it. Look at MainPage.xaml.cs and swipe until you reach the start/end. I'm testing directly on the device (iPad).

Infinite scrolling is not currently supported but, it will be in the next release that will be out in the next few days.

Thanks for the update. I'll be glad to test this new feature, when it is released.

wegascee commented 5 years ago

Any new info about this?

alexrainman commented 5 years ago

Soon.
