If the ViewHolder is still being drawn on the RecyclerView even after calling notifyItemRemoved(), it's possible that the RecyclerView is not properly recycling the ViewHolder instances. | |
One common reason for this is that the RecyclerView is unable to correctly identify the view type of the ViewHolder instance that should be recycled. When you override the getItemViewType() method of your RecyclerView.Adapter, make sure that you are returning the correct view type for each item in your dataset. | |
Another reason could be that the RecyclerView is not properly removing the ViewHolder instance from its internal cache. This could happen if you have implemented custom animations that prevent the ViewHolder from being properly removed, or if there is a memory leak in your code that is preventing the ViewHolder from being garbage collected. | |
To troubleshoot this issue, you can try the following: | |
Check if you're accidentally creating multiple instances of the same item. If the same item is present multiple times in your dataset, removing one instance of the item may not remove the corresponding ViewHolder. | |
Try disabling any custom animations to see if this resolves the issue. | |
If you suspect a memory leak, use a memory profiler to identify any potential leaks in your code. | |
You can also try manually removing the ViewHolder instance from the RecyclerView by calling recyclerView.removeView(viewHolder.itemView) in your RecyclerView.Adapter after calling notifyItemRemoved(). This will force the RecyclerView to remove the ViewHolder instance from its internal cache. | |
If none of these suggestions help, you may need to provide more information or code to help diagnose the problem. |
