Hi Nguyen,

Greetings from Syncfusion.

We have checked the reported issue. To resolve the issue, we recommend that you use the parent layout for the SfPullToRefresh control, as shown in the code snippet below.

Code snippet 

<tab:SfTabItem.Content> 

                <Grid> 

                <pull:SfPullToRefresh Pulling="SfPullToRefresh_Pulling" Refreshing="SfPullToRefresh_Refreshing"> 

                    <pull:SfPullToRefresh.PullableContent> 

                        <sync:SfListView x:Name="listView"  

                           ItemsSource="{Binding BookInfo}" 

                           ItemSize="100" 

                           ItemTapped="listView_ItemTapped"> 

                            <sync:SfListView.ItemTemplate> 

                                <DataTemplate> 

                                    <Grid Padding="10"> 

                                        <Grid.RowDefinitions> 

                                            <RowDefinition Height="0.4*" /> 

                                            <RowDefinition Height="0.6*" /> 

                                        </Grid.RowDefinitions> 

                                        <Label x:Name="label" Text="{Binding BookName}" FontSize="21" FontAttributes="Bold"/> 

                                        <Label Grid.Row="1" Text="{Binding BookDescription}" FontSize="15"/> 

                                    </Grid> 

                                </DataTemplate> 

                            </sync:SfListView.ItemTemplate> 

                        </sync:SfListView> 

                    </pull:SfPullToRefresh.PullableContent> 

                </pull:SfPullToRefresh> 

                </Grid> 

            </tab:SfTabItem.Content>

I dont want to use any View to show that, because it may cause my application spend more RAM.

No way to fix that without add other view?

There is a bug? Your team will fix or not?

Thanks.

Hi Nguyen,​

Thanks for your patience.

On further analysis with the source, we would like to inform you that the reported issue occurs due to the IsClippedToBounds property set to true in PullToRefresh source. So that the tab view tab item content is not rendered in Android. This is related to xamarin forms framework issue. We have already asked a query in Xamarin.Forms discussion page. Please find the Xamarin.Forms discussion page from below link 

Link: https://github.com/xamarin/Xamarin.Forms/issues/7464 

We suggest you set the IsClippedToBounds property to false in PullToRefresh or use the pull to refresh inside the grid to resolve the reported issue. We have modified the sample based on this and please find the sample from the below link

Sample Link: https://www.syncfusion.com/downloads/support/directtrac/general/ze/GettingStarted83461987

Code Snippet: 

                <pull:SfPullToRefresh  Pulling="SfPullToRefresh_Pulling" IsClippedToBounds="false" Refreshing="SfPullToRefresh_Refreshing"> 

Please check with the above and let us know if you have any concerns.
