RadListView StaggeredLayout问题

Question

我有一个Nativescript角项目，我正在使用RadListView尝试使用交错布局。它在Android上运行得很好，但是在iOS上存在一个间隔问题，我不知道是什么原因造成的。

<GridLayout class="page page-content" rows="*">
        <GridLayout margin="10">
                <RadListView height="100%" [items]="dataItems">
                        <ng-template tkListItemTemplate let-item="item" backgroundColor="transparent">
                                <StackLayout rows="auto, auto" borderWidth="1" borderColor="#ccc" margin="10">
                                        <Label class="h3" [text]="item.name"></Label>
                                        <Label class="descriptionLabel" [text]="item.description" textWrap="true"></Label>
                                </StackLayout>
                        </ng-template>
                        <ListViewStaggeredLayout tkListViewLayout scrollDirection="Vertical" spanCount="2"></ListViewStaggeredLayout>
                </RadListView>
        </GridLayout>
</GridLayout>

TypeScript

dataItems = [{name: "Item 1", description: "Lorem ipsum dolor sit amet."},
                 {name: "Item 2", description: "Maecenas ac massa eu odio porta efficitur at non leo"}, 
                 {name: "Item 3", description: "Nunc vitae tortor sodales, varius magna quis, faucibus justo."},
                 {name: "Item 4", description: "In finibus sem"},

                 {name: "Item 10", description: "In sed dolor sit amet velit tempus iaculis."},
                 {name: "Item 11", description: "Duis dictum nunc in neque"},
                 {name: "Item 12", description: "Mauris dignissim mi sit amet nulla tristique, id posuere urna volutpat mauris gravida purus."},
                 {name: "Item 13", description: "Etiam accumsan sapien eget eros convallis porttitor."}, 
                 {name: "Item 14", description: "Vivamus ac arcu"},
                 {name: "Item 15", description: "Vestibulum at elit eget sapien fringilla"},
                 {name: "Item 16", description: "Maecenas tempus enim et velit bibendum, eu consequat erat volutpat."}]; 

Answer 1

不管有没有额外的GridLayouts，我都无法在我的头上重现这个问题。至少在我看来，这些布局实际上并不是必需的。这是与游乐场的连结。
