android - 本地源图像绑定(bind)到 MvxImageView

Question

 public class DrawerView
{
    public string ListItem{get;set;}
    public string icon{ get; set;}
    public DrawerView (string Litems,string ic)
    {
        this.ListItem = Litems;
        this.icon = ic;
    }
}

 public class MainViewModel:MvxViewModel
{
    public List<DrawerView> drawerlist{ get; set;}
    public MainViewModel ()
    {
        drawerlist = new List<DrawerView> ();
        drawerlist.Add (new DrawerView ("Home","@drawable/Home"));
        drawerlist.Add (new DrawerView ("My Addresses","@drawable/Home"));
        drawerlist.Add (new DrawerView ("My Cart","/@drawable/Home"));
        drawerlist.Add (new DrawerView ("My Orders","@drawable/Home"));
        drawerlist.Add (new DrawerView ("Notification","@drawable/Home"));
    }
}


 <Mvx.MvxImageView
    android:layout_height="wrap_content"
    android:layout_width="wrap_content"
    android:padding="10dp"
    local:MvxBind="ImageUrl 'res:icon'"
    />

当我使用图像 url 绑定(bind)本地 @drawable/Home 图像时，我无法在 View 中获取图像。如何在 MvxImageView 中绑定(bind)本地源图像？上面代码中的图标是我的字符串属性，它需要@drawable/images。

这是我使用转换器的方式:

<Mvx.MvxImageView
    android:id="@+id/team_trend"
    android:layout_width="24dp"
    android:layout_height="8dp"
    android:gravity="center_vertical"
    android:layout_gravity="center"
    android:adjustViewBounds="true"
    local:MvxBind="ImageUrl RowItem.TeamTrendEnum, Converter=TeamTrendImage" />

我的转换器返回图像:

public class TeamTrendImageValueConverter : MvxValueConverter
{
    public override object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)
    {            
        var teamTrend = TeamTrendEnumeration.None;

        if (value != null)
            teamTrend = (TeamTrendEnumeration)value;

        switch (teamTrend)
        {
            case TeamTrendEnumeration.High: 
                return "res:th";

            ...                                           
        }

        return "res:none";                  
    }
}

您是否尝试过删除引号？
