上面的代码应该在顶部为您提供一个固定的搜索栏，带有一个可滚动的ListView。如果您仍然有问题，请共享一个游乐场示例，以便重现问题。

您需要用代码进一步解释您的问题also@KhurshidAnsari我来看看。

                <StackLayout class="form">
                        <SearchBar [formControl]="searchControl" class="input"></SearchBar>
                    </StackLayout>

            <ListView [items]="_batches" (itemTap)="onItemTap($event)" class="list-group">

                <ng-template let-comment="item" let-i="index" let-odd="odd" let-even="even">
                    <!-- The item template can only have a single root view container (e.g. GridLayout, StackLayout, etc.)-->
                    <StackLayout orientation="horizontal" class="list-group-item" ><StackLayout width="200" height="45">
