将AutomationID与ListView一起使用 [英] Using AutomationID with ListView

问题描述

我正在尝试将AutomationId附加到列表视图中的项目.理想情况下，将项目名称绑定到显示的项目.

I'm trying to attach an automationId to items within a listview. Ideally by binding a project name to the item that is shown.

<ListView
ItemsSource="{Binding Projects}"
AutomationId="{Binding Projects}
HasUnevenRows="True"
IsPullToRefreshEnabled="true"
CachingStrategy="RecycleElement"
HorizontalOptions="FillAndExpand"
VerticalOptions="FillAndExpand">  

当我进入页面时，代码正在部署但未运行，是否有人找到了很好的解决方法来绑定ID?

The code is deploying but not running when I get to the page, has anyone found a good workaround to bind the ID like that?

长期来看，我想将其与Xamarin Forms滚动功能一起使用，该功能可以滚动到标记的项目，但不能滚动到显示的文本.

Long term, I want to use it with the Xamarin Forms ability to scroll which can scroll to a marked item, but not scroll to a displayed text.

推荐答案

AutomationId 不是可绑定的属性，在Xamarin.Forms源代码中很明显:

AutomationId is not a bindable property as apparent in the Xamarin.Forms source code:

Xamarin.Forms.Core.Element.cs

string _automationId;


public string AutomationId
{
    get { return _automationId; }
    set
    {
        if (_automationId != null)
            throw new InvalidOperationException("AutomationId may only be set one time");
        _automationId = value;
    }
}

一些人在与此同时，您需要对 AutomationId 进行硬编码，并牢记硬编码的id来构建UI测试.

You'll need to hard code the AutomationId for the meantime and build your UI tests with a hard coded id in mind.
