我创建了一个包含不同类型 subview 的社交帖子回收 View 。
每个 child 多个 layout.recyclerview 工作正常，唯一的问题是 recyclerview 滚动不流畅。
我们的代码
@Override
public int getItemViewType(int position) {
if (arrSocial_Post_Model.get(position) != null) {
Social_Post_Model objSocial_Post_Model = arrSocial_Post_Model.get(position);
if (objSocial_Post_Model.getPost_type().equalsIgnoreCase("1"))
return VIEW_FRIEND_SUGGESTION;
else if (objSocial_Post_Model.getPost_type().equalsIgnoreCase("special_post") ||
objSocial_Post_Model.getPost_type().equalsIgnoreCase("2") ||
objSocial_Post_Model.getPost_type().equalsIgnoreCase("3"))
return VIEW_SPECIAL_POST;
else if (objSocial_Post_Model.getPost_type().equalsIgnoreCase("4") ||
objSocial_Post_Model.getPost_type().equalsIgnoreCase("5") ||
objSocial_Post_Model.getPost_type().equalsIgnoreCase("6"))
return VIEW_INFLUNENCER_POST;

return VIEW_PURCHASE_SUGGESION;

我们使用了 3 个与上述 viewholder 相同的 viewholder
最佳答案
我知道，我来晚了一点，但我很确定你的问题是因为你正在使用 de.hdodenhof.circleimageview.CircleImageView。
在列表中使用此自定义 ImageView 时，性能似乎很差。我建议使用另一种方法将图像转换为圆圈。
