如何在Xamarin.Forms上将图像加载到ImageCell? [英] How to load an image to a ImageCell on Xamarin.Forms?

问题描述

我试图将图标加载到ListView内的ImageCell中，但是当我构建项目时，该图标没有出现在ImageCell上.

I'm trying to load icons into a ImageCell inside a ListView, but when I build my project the icon doesn't appear on the ImageCell.

这是我的项目结构:

这是我的XAML页面:

Here's my XAML page:

<?xml version="1.0" encoding="utf-8" ?>
<MasterDetailPage xmlns="http://xamarin.com/schemas/2014/forms"
             xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
             x:Class="MyNotes.StartPage">

  <MasterDetailPage.Master Title="Menu">
    <ContentPage Title="Menu">
      <StackLayout VerticalOptions="FillAndExpand">
        <ListView x:Name="listViewMaster" VerticalOptions="FillAndExpand">
          <ListView.ItemTemplate>
            <DataTemplate>
              <ImageCell Text="{Binding Title}" ImageSource="{Binding IconSource}" />
            </DataTemplate>
          </ListView.ItemTemplate>
        </ListView>
      </StackLayout>
    </ContentPage>
  </MasterDetailPage.Master>

  <MasterDetailPage.Detail>
    <ContentPage>

    </ContentPage>
  </MasterDetailPage.Detail>

</MasterDetailPage>

这是背后的代码:

using System.Collections.Generic;
using Xamarin.Forms;

namespace MyNotes
{
    public partial class StartPage : MasterDetailPage
    {
        public StartPage ()
        {
            InitializeComponent ();

            List<MasterPageItem> masterPageItems = new List<MasterPageItem>()
            {
                new MasterPageItem()
                {
                    Title = "Contacts",
                    IconSource = ImageSource.FromFile(@"c:\Projetos\MyNotes\MyNotes\MyNotes\Resources\image\contacts.png"),
                    TargetType = typeof(ContactPage)
                },
                new MasterPageItem()
                {
                    Title = "Todo List",
                    IconSource = ImageSource.FromFile(@"Resources\image\todo.png"),
                    TargetType = typeof(TodoListPage)
                },
                new MasterPageItem()
                {
                    Title = "Reminder",
                    IconSource = ImageSource.FromResource("Resources.image.reminder.png"),
                    TargetType = typeof(ContactPage)
                }
            };

            listViewMaster.ItemsSource = masterPageItems;
        }
    }
}

我在做什么错了?

推荐答案

图像进入您的本地"项目:

The images go into your "native" projects:

• Xamarin.iOS = BundledResource构建类型

Xamarin.Android = AndroidResource构建类型

Xamarin.Android = AndroidResource Build Type

IconSource = ImageSource.FromFile("SanFran.jpg")

或使用隐式转换:

IconSource = "SanFran.jpg";
