Listview 具有列表视图和详细视图的Xamarin表单应用程序

我正在寻找一个解决方案，拥有一个列表视图，其中包含列表中的项目，这是可行的，我希望这样，如果我单击列表中的某个项目，我将获得该项目的详细视图

因此，我的问题是，如何将详图视图绑定到所选项目。 这就是我目前的数据来源

public class Friend
{
    public int Id { get; set; }
    public string Name { get; set; }
    public string Address { get; set; }
    public int PhoneNumber { get; set; }
    public string Email { get; set; }
    public Uri Picture { get; set; }
    public string GPS { get; set; }
    public Uri URL { get; set; }

    public override string ToString()
    {
        return Name + " Address: " + Address + " Phone Number: " + PhoneNumber;
    }
    //firend data
    public static List<Friend> GetList()
    {
        var friends = new List<Friend>();
        friends.Add(new Friend { Id = 1, Name = "t1", Email = "t1@t1.com", Address = "xx", GPS = "22t,e33", PhoneNumber = 523254854, Picture = new Uri(""), URL = new Uri("") });
        friends.Add(new Friend { Id = 2, Name = "t2", Email = "t1@t1.com", Address = "xx", GPS = "22t,e35", PhoneNumber = 222222, Picture = new Uri(""), URL = new Uri("") });
        friends.Add(new Friend { Id = 3, Name = "t3", Email = "t1@t1.com", Address = "xx", GPS = "22t,e38", PhoneNumber = 111111, Picture = new Uri(""), URL = new Uri("") });

        return friends;
    }
}

谢谢

Jason是正确的您的代码是正确的，但这可能会让您头脑清醒：

private async void MainListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
    if (e.SelectedItem != null)
    {
        Friend friend = e.SelectedItem as Friend;
        await Navigation.PushAsync(new FriendPage(friend));
        ((ListView)sender).SelectedItem = null;
    }
}

//Where
//FriendPage:

public class FriendPage : ContentPage
{
    public FriendPage(Friend friend)
    {
        //... friend parameter will have the selected list item.
    }   
}

有什么问题？你所做的通常是正确的方法。在将e.SelectedItem传递到第1页之前，您可能想尝试将其强制转换为Friend，但我看不出有任何问题。

private async void MainListView_ItemSelected(object sender, SelectedItemChangedEventArgs e)
{
    if (e.SelectedItem != null)
    {
        Friend friend = e.SelectedItem as Friend;
        await Navigation.PushAsync(new FriendPage(friend));
        ((ListView)sender).SelectedItem = null;
    }
}

//Where
//FriendPage:

public class FriendPage : ContentPage
{
    public FriendPage(Friend friend)
    {
        //... friend parameter will have the selected list item.
    }   
}
