我想显示存储在我的 App 目录中的 Svg 图像我编写了一个代码来显示存储在可绘制文件夹中的图像，但我想显示来自我的应用程序目录的图像以及图像存储在“Android/data/QR.Android/文件/Q317664.svg"

using System;
using System.Linq;
using System.Reflection;

using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using XamSvg;
using Android.Graphics;

namespace QR.Android
{
[Activity(Label = "Activity3",Theme = "@android:style/Theme.Holo.Light.NoActionBar.Fullscreen")]
public class Activity3 : Activity
{
int[] rawIds;
    int[] drawableViewIds;
    private string[] sharedNames;

    int currentId;


    protected override void OnCreate(Bundle bundle)
    {
        base.OnCreate(bundle);
        SetContentView(Resource.Layout.layout1);

        //Initialize the cross platform color helper
        Setup.InitSvgLib();

        //Tells XamSvg in which assembly to search for svg when "res:" is used
        var assembly = typeof(AppDomain).GetTypeInfo().Assembly;
        XamSvg.Shared.Config.ResourceAssembly = assembly;





        //Get all svg resource ids in the raw folder
        rawIds = typeof(Resource.Drawable)
            .GetFields()
            .Where(f => f.IsLiteral)
            .Select(f => (int)f.GetRawConstantValue())
            .ToArray();

        //Get all drawing zones in the current layout
        drawableViewIds = typeof(Resource.Id)
            .GetFields()
            .Where(f => f.IsLiteral && f.Name.StartsWith("drawable"))
            .Select(f => (int)f.GetRawConstantValue())
           .ToArray();

        //Get all svg resources in the shared assembly
        sharedNames = assembly.GetManifestResourceNames().Where(n => n.EndsWith(".svg")).OrderBy(n => n).ToArray();

        //When clicked, change the svg source in all zones
        var contentView = FindViewById(Resource.Id.content);
        currentId = currentId + 2;
       contentView.Click += (sender, e) =>
        {
            if (currentId < rawIds.Length)
                LoadImageTest(rawIds[currentId]);
            //    else
            //        LoadImageTest(sharedNames[currentId-rawIds.Length]);

            //    currentId = (++currentId)%(rawIds.Length+sharedNames.Length);
        };




        LoadImageTest(rawIds[currentId++]);

    }

    void LoadImageTest(int rawId)
    {
        foreach (var drawableId in drawableViewIds)
        {
         //   if (drawableID != Resource.Id.drawable100)
           //     continue;

            var v = FindViewById<ImageView>(drawableId);
           var drawable = SvgFactory.GetDrawable(Resources, rawId);
         v.SetImageDrawable(drawable);
        }
    }


}
}
