推荐答案

正如@mindOfAi所说，您应该能够使用ItemClick事件.它发生在列表视图中的项收到交互并且IsItemClickEnabled时属性是真实的.我们可以通过 ItemClickEventArgs.ClickedItem 属性.

As @mindOfAi said, you should be able to use the ItemClick event.It occurs when an item in the list view receives an interaction, and the IsItemClickEnabled property is true. And we can get item by the ItemClickEventArgs.ClickedItem property.

在发布的代码中，似乎您定义了人员实例，并通过buttonAdd_Click事件设置了数据.我们找不到在哪里设置 ListView的Itemsource .

From the code that you posted, it seems you define a person instance, and set the data by the buttonAdd_Click event. We can not find where do you set the Itemsource of the ListView.

您应该能够将您的person对象添加到集合中，并且我们可以将集合设置为Itemsource.然后我们可以通过ItemClick事件获得ClickedItem.

You should be able to add your person object to the collection, and we can set the collection to the Itemsource. Then we can get the ClickedItem by the ItemClick event.

例如:

private ObservableCollection<Person> Persons;

public MainPage()
{
    this.InitializeComponent();
    this.NavigationCacheMode = NavigationCacheMode.Required;
    Persons = new ObservableCollection<Person>();

    for (int i = 0; i < 10; i++)
    {
        Persons.Add(new Person());
        Persons[i].Contact = "Contact" + i;
        Persons[i].Gender = "Gender" + i;
        Persons[i].ImagePath = "ms - appx:///Assets/tiles/boy.png";
        Persons[i].Name = "Name" + i;
    }
    listViewDirectory.ItemsSource = Persons;
}
