Question

我有不同数量的图像（从1到8）。图片显示在prenotazioni GridLayoutManager。

UniversalImageLoader

适配器中的GridLayoutManager（Xamarin Android / C＃），但它类似于Android / Java）：

        <android.support.v7.widget.RecyclerView
            android:id="@+id/sharedGridLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="center"
            local:layout_behavior="@string/appbar_scrolling_view_behavior"
            android:layout_below="@id/expandTextView" />

的xml：

 GridLayoutManager layoutManager = null;
                        if (item.UserImages.Count == 1)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 1);
                        }
                        if (item.UserImages.Count == 2)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 2);
                        }
                        else if (item.UserImages.Count == 3)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 3);
                        }
                        else if (item.UserImages.Count == 4)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 2);
                        }
                        else if (item.UserImages.Count == 5)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 4);
                            layoutManager.SetSpanSizeLookup(new MySpanSizeLookup(5));
                        }
                        else if (item.UserImages.Count == 6)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 3);
                        }
                        else if (item.UserImages.Count == 7)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 3);
                            layoutManager.SetSpanSizeLookup(new MySpanSizeLookup(7));
                        }
                        else if (item.UserImages.Count == 8)
                        {
                            layoutManager = new GridLayoutManager(_activityContext, 4);
                        }
                        vh.RecyclerGridView.NestedScrollingEnabled = false;
                        vh.RecyclerGridView.SetLayoutManager(layoutManager);
                        var photoImageAdapter = new PhotoListItemAdapter(_imageLoader, vh.RecyclerGridView, item.UserImages, _activityContext);
                        vh.RecyclerGridView.SetAdapter(photoImageAdapter);

当我快速滚动GridLayoutManager的高度显示错误时：

如何解决？

我尝试重新绘制recyclerview，但它没有帮助：
