I have a problem only on Android. My items in Listview don't update sometimes. I open a view and I see item without text or space (screen 1-2). I scroll down and then scroll up. Item redrawes and text is shown or space is removed (screen 3)
How can I fix it?

My List:

    <Grid BackgroundColor="{Binding ListViewCustomizer.DefaultBackgroundColor}">

        <Grid.RowDefinitions>

            <RowDefinition Height="*"/>

        </Grid.RowDefinitions>



        <recycle:RecycleListView ItemsSource="{Binding NewsFeedItems}" 

                VerticalOptions="FillAndExpand" HorizontalOptions="FillAndExpand"

                ShowAdvertisementEvery="10"

                ItemSelected="HandleItemSelected" RefreshCommand="{Binding RefreshCommand}"

                RowSpacing="0" ItemMargin="0"

                LoadMoreCommand="{Binding LoadMoreCommand}"

                IsLoadMoreEnabled="True" 

                IsLoadingMore="{Binding IsOldestLoading}"

                IsRefreshing="{Binding IsRefreshing}"

                IsPullToRefreshEnabled="True">

            <recycle:RecycleListView.IsAdvertisementEnabled>

                <OnPlatform x:TypeArguments="x:Boolean">

                  <OnPlatform.iOS>

                    false

                  </OnPlatform.iOS>

                  <OnPlatform.Android>

                    true

                  </OnPlatform.Android>

                </OnPlatform>

            </recycle:RecycleListView.IsAdvertisementEnabled>

            <recycle:RecycleListView.ItemHeight>

                <extensions:OnDeviceType x:TypeArguments="x:Double" Phone="130" Tablet="200"/>

            </recycle:RecycleListView.ItemHeight>

            <recycle:RecycleListView.Padding>

                <OnPlatform x:TypeArguments="Thickness">

                  <OnPlatform.iOS>

                    0, 0, 0, 0

                  </OnPlatform.iOS>

                  <OnPlatform.Android>

                    0, 0, 0, 5

                  </OnPlatform.Android>

                </OnPlatform>

            </recycle:RecycleListView.Padding>

            <recycle:RecycleListView.ItemTemplate>

                <DataTemplate>

                    <viewCells:NewsFeedListItem/>

                </DataTemplate>

            </recycle:RecycleListView.ItemTemplate>

        </recycle:RecycleListView>    </Grid>

There RecycleListView is a renderer.

Renderer:

    protected RecyclerView _recyclerView;

    protected RecycleListViewAdapter _adapter;

    protected SwipeRefreshLayout _refresh;

    protected RecyclerView.ItemDecoration _itemDecoration;

    protected RecycleScrollListener _scrollListener;



    protected override void OnElementChanged(ElementChangedEventArgs<RecycleListView> e)

    {

        base.OnElementChanged(e);

        if (e.NewElement != null)

        {

            CreateNativeElement();

            SetNativeControl(_refresh);

        }

    }



protected void CreateNativeElement()

    {

        _recyclerView = new RecyclerView(Android.App.Application.Context);

        _recyclerView.HasFixedSize = true;

        _recyclerView.SetLayoutManager(new LinearLayoutManager(Context, OrientationHelper.Vertical, false));

        _recyclerView.SetItemAnimator(new DefaultItemAnimator());

        _recyclerView.HorizontalScrollBarEnabled = false;

        _recyclerView.VerticalScrollBarEnabled = true;

        var pool = _recyclerView.GetRecycledViewPool();

        pool.SetMaxRecycledViews(RecycleListViewAdapter.ADVERTISEMENT_VIEW_TYPE, 1);

        pool.SetMaxRecycledViews(RecycleListViewAdapter.DEFAULT_VIEW_TYPE, 25);



        _scrollListener = new RecycleScrollListener();

        _scrollListener.Loading += (object sender, EventArgs args) => { OnLoadMore(); };



        UpdateIsLoadMoreEnabled();



        _adapter = new RecycleListViewAdapter(

            Context,

            Element.ItemsSource,

            _recyclerView,

            Element,

            Resources.

            DisplayMetrics,

            Element.IsAdvertisementEnabled,

            Element.ShowAdvertisementEvery);



        _recyclerView.SetAdapter(_adapter);



        _itemDecoration = new SpacesItemDecoration(

            ConvertDpToPixels(Element.RowSpacing),

            ConvertDpToPixels(Element.ItemMargin.Left),

            ConvertDpToPixels(Element.ItemMargin.Top),

            ConvertDpToPixels(Element.ItemMargin.Right),

            ConvertDpToPixels(Element.ItemMargin.Bottom)

        );



        _recyclerView.AddItemDecoration(_itemDecoration);



        _refresh = new SwipeRefreshLayout(Android.App.Application.Context);

        _refresh.SetOnRefreshListener(this);

        _refresh.AddView(_recyclerView, LayoutParams.MatchParent);

    }
