Some different requirement i'm using nested ListView in XAMRIN form. It's working perfect in IOS. But in Android it's crashing when scrolling the ListView item then giving the following exception as:
Unable to activate instance of type Xamarin.Forms.Platform.Android.ListViewAdapter from native handle 0x7fd2839b14 (key_handle 0x4219316).
No constructor found for Xamarin.Forms.Platform.Android.ListViewAdapter::.ctor(System.IntPtr, Android.Runtime.JniHandleOwnership
Exception of type 'Java.Interop.JavaLocationException' was thrown.

ListView Custom Renderer Code:
public class HideScrollListViewRender:ListViewRenderer
{
Context _context;
public HideScrollListViewRender(Context context):base(context)
{
_context = context;
}
protected override void OnDetachedFromWindow()
{
if (Element == null)
return;
base.OnDetachedFromWindow();
}
protected override void OnElementChanged(ElementChangedEventArgs<Xamarin.Forms.ListView> e)
{
base.OnElementChanged(e);
}
CellView Custom Renderer Code:
public class CustomAllViewCellRenderer:ViewCellRenderer
{
public override UIKit.UITableViewCell GetCell(Cell item, UIKit.UITableViewCell reusableCell, UIKit.UITableView tv)
{
var cell = base.GetCell(item, reusableCell, tv);
if (cell != null)
cell.SelectionStyle = UIKit.UITableViewCellSelectionStyle.None;
return cell;
}
}
The exceptions is only in xamarin form Android. What's wrong with the code?
