image - 画廊不显示？

Question

所以我添加了在我的应用上上传个人资料图片的选项。但是当用户尝试上传个人资料图片时，只有相机显示。不显示画廊（下面是我使用的代码）

public void OpenIntentImageGallery(string title, bool allowMultiple, bool imageCropping = true)
        {
            try
            {
                if (!MSTools.CheckAllowedFileUpload())
                {
                    Methods.DialogPopup.InvokeAndShowDialog(Context, Context.GetText(Resource.String.Lbl_Security), Context.GetText(Resource.String.Lbl_Error_AllowedFileUpload), Context.GetText(Resource.String.Lbl_Ok));
                    return;
                }

                Methods.Path.Chack_MyFolder();

                Intent intent = (int)Build.VERSION.SdkInt switch
                {
                    <= 25 => new Intent(Intent.ActionPick, MediaStore.Images.Media.ExternalContentUri),
                    _ => Android.OS.Environment.GetExternalStorageState(null)!.Equals(Android.OS.Environment
                        .MediaMounted)
                        ? new Intent(Intent.ActionPick, MediaStore.Images.Media.ExternalContentUri)
                        : new Intent(Intent.ActionPick, MediaStore.Images.Media.InternalContentUri)
                };

                intent.SetType("image/*");
                intent.PutExtra("return-data", true); //added snippet

                switch (Build.VERSION.SdkInt)
                {
                    case > BuildVersionCodes.Q:
                        intent.SetAction(Intent.ActionGetContent);
                        break;
                }

                if (imageCropping && Build.Manufacturer!.ToLower() == "samsung")
                {
                    intent.PutExtra("crop", "true");
                    var myUri = Uri.FromFile(new File(Methods.Path.FolderDcimImage, Methods.GetTimestamp(DateTime.Now) + ".jpeg"));
                    intent.PutExtra(MediaStore.ExtraOutput, myUri);
                    //intent.PutExtra("outputFormat", Bitmap.CompressFormat.Jpeg.ToString());
                }

                switch (allowMultiple)
                {
                    case true:
                        intent.PutExtra(Intent.ExtraAllowMultiple, true);
                        break;
                }

                if (intent.ResolveActivity(Context.PackageManager) != null)
                    Context.StartActivityForResult(Intent.CreateChooser(intent, title), 500);
            }
            catch (Exception e)
            {
                Methods.DisplayReportResultTrack(e);
            }
        }
