How to use

1. Download this project and copy Assets/InfiniteScrollView to your own project

2. There are three class you have to inherit and implement by your own context
   InfiniteCellData
InfiniteCell
VerticalInfiniteScrollView, HorizontalInfiniteScrollView or VerticalGridInfiniteScrollView

3. Create CSharp script named DemoVerticalDate and inherit InfiniteCellData

using HowTungTung;
public class DemoVerticalData : InfiniteCellData
{
    public DemoVerticalData(float height)
    {
        cellSize.y = height;
    }
}

4. Create CSharp script named DemoVerticalCell and inherit InfiniteCell<DemoVeritcalData>

using UnityEngine;
using UnityEngine.UI;
using HowTungTung;
public class DemoVerticalCell : InfiniteCell<DemoVerticalData>
{
    public Text text;
    public override void OnUpdate()
    {
        RectTransform.sizeDelta = new Vector2(RectTransform.sizeDelta.x, CellData.cellSize.y);
        text.text = CellData.cellSize.y.ToString();
    }
}

5. Create CSharp script named DemoVerticalScrollView and inherit VerticalInfiniteScrollView<DemoVerticalData>

using HowTungTung;
public class DemoVerticalScrollView : VerticalInfiniteScrollView<DemoVerticalData>
{
}

6. Create CSharp script named Tester only for test purpose

using HowTungTung;
public class Tester : MonoBehavior
{
   private void Start()
   {
       var infiniteScrollView = FindObjectOfType<DemoVerticalScrollView>();
       for (int i = 0; i < 100; i++)
       {
           var data = new DemoVerticalData(Random.Range(50, 300));
           infiniteScrollView.Add(data);

12. Delete the Button from Hierarchy
13. Select Scroll View and attach DemoVerticalScrollView then drag the prefab we just created on Cell Prefab field of the DemoVerticalScrollView component
