Create select dropwdown picker to filter values in xamarin
问题
我希望用户从列表中选择他们的症状。这将是一个非常长的列表，所以我希望能够进行筛选，同时也要有适当的下拉选择项。类似于这样的东西：
有Xamarin.Forms Picker（https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/picker/），但它只能显示一个列表以供选择，对吗？没有输入的可能性。
如何在Xamarin Forms中实现类似图片的东西？
英文:
I want user to select their symptoms from a list. It is gonna be a very long list so I would like to filter it but at the same time have proper dropdown select item. Something like this:
There is Xamarin.Forms Picker (https://learn.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/picker/) but it can only display itewms in a list to select, right? No possibility to input.
How can I achieve something similar like picture in Xamarin Forms?

您可以使用搜索栏或Xamarin.Forms Shell搜索来实现您想要的元素。
<SearchBar Placeholder="搜索项目..."
CancelButtonColor="橙色"
PlaceholderColor="橙色"
TextColor="橙色"
TextTransform="小写"
HorizontalTextAlignment="居中"
FontSize="中号"
FontAttributes="斜体" />
