ImageSlider using ViewPager not showing image which gets removed in destroyitem

I am trying to make a mix image/video slider using viewpager, I have made an adapter for that and in instantiateItem overridden by pagerAdapter I assign a view to imageView or videoView.

below is the code of that

    public override Java.Lang.Object InstantiateItem(ViewGroup container, int position)
    {
        View view = new View(_context);
        var plItem = this._viewSources[position];

        try
        {
            if (!plItem.Contains("mp4"))
            {
                view = new ImageView(_context);
                view.Tag = position;
                ((ImageView)view).SetImageURI(Uri.Parse(plItem));
                ((ImageView)view).SetScaleType(ImageView.ScaleType.FitXy);
            }
            else
            {
                view = new VideoView(_context);
                view.Tag = position;

                RelativeLayout.LayoutParams layoutparams = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.MatchParent, RelativeLayout.LayoutParams.MatchParent);

                ((VideoView)view).LayoutParameters = layoutparams;
                ((VideoView)view).SetVideoPath(plItem);
                ((VideoView)view).Completion += View_Completion;
                ((VideoView)view).Start();
            }

            ((ViewPager)container).AddView(view, 0);
        }
        catch (Exception ex)
        {

        }

        return view;

        //((Activity)_context).RunOnUiThread(() =>
        //{
        //    container.AddView(view, 0);
        //});
        //return view;
    }

and I have also overridden destroyItem in which I delete the view from container

    public override void DestroyItem(ViewGroup container, int position, Java.Lang.Object @object)
    {
        try
        {
            ((ViewPager)container).RemoveView((View)@object);
            //GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced);
        }
        catch (Exception ex)
        {
        }
    }

i am calling my viewpager in another custom control using this code

        _viewPager = new ViewPager(_context);
        _viewPager.OffscreenPageLimit = 2;
        _viewPager.SetBackgroundColor(Android.Graphics.Color.Transparent);
        _viewPager.Adapter = new ImageVideoSliderAdapter(_context, _viewPager);
        _viewPager.AddOnPageChangeListener((IOnPageChangeListener)_viewPager.Adapter);

The main problem I am facing is when an item is removed from the container it shows an empty imageview in that iteration with no image

The problem was on destroy item it was throwing exception that only I must delete view in ui thread that's why it was not getting properly deleted.

            ((Activity)_context).RunOnUiThread(() =>
            {
                ((ViewPager)container).RemoveView((View)@object);
            });

after doing this the problem was fixed.
