Sead Lab :
I have 3 parts of data displayed in one RecyclerView:
storyListyukulListhomeList
When I've tried to display only storyList or yukulList or homeList data in RecyclerView, it works. But when I've tried to display more than one data, for example: storyList && yukulList or storyList && yukulList && homeList, it will show
java.lang.IndexOutOfBoundsException.
I've tried to add notifyDataSetChanged() but it can't works.

Ben P. :
In your adapter, the collection list is the only list that's safe to access using position. Trying to call yukulList.get(position) is guaranteed to eventually throw an exception.
All of these lines in onBindViewHolder() are unsafe and should be changed:
@Override public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) { // ... ((tidurViewHolder) holder).bind(storyList.get(position)); // ... ((yukulViewHolder) holder).bind(yukulList.get(position)); // ... ((homeViewHolder) holder).bind(homeList.get(position)); // ... }
You can access the "view type" value that you've returned from getItemViewType() by calling holder.getItemViewType(), and you can use that to determine the right type of view holder and item to use:
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
Object item = collection.get(position);
int adapterPosition = holder.getAdapterPosition();
if (holder.getItemViewType() == VIEW_TYPE_TIDUR){
Story story = (Story) item;
tidurViewHolder vh = (tidurViewHolder) holder;
vh.bind(story);
vh.setViewData(story, adapterPosition);
} else if (holder.getItemViewType() == VIEW_TYPE_YUKUL){
YukulModel yukul = (YukulModel) item;
yukulViewHolder vh = (yukulViewHolder) holder;
vh.bind(yukul);
vh.viewDataYukul(yukul, adapterPosition);
} else if (holder.getItemViewType() == VIEW_TYPE_HOME){
HomeModel home = (HomeModel) item;
homeViewHolder vh = (homeViewHolder) holder;
vh.bind(home);
vh.viewDataHome(home, adapterPosition);
}
}
Note also that there's no need to actually pass holder.getAdapterPosition() into e.g. setViewData(), since you can simply call getAdapterPosition() from within the tidurViewHolder method.
And I would also say that you could combine your bind() and setViewData() calls into one, which would leave you with this:
@Override
public void onBindViewHolder(@NonNull RecyclerView.ViewHolder holder, int position) {
Object item = collection.get(position);
if (holder.getItemViewType() == VIEW_TYPE_TIDUR){
((tidurViewHolder) holder).bind((Story) item);
} else if (holder.getItemViewType() == VIEW_TYPE_YUKUL){
((yukulViewHolder) holder).bind((YukulModel) item);
} else if (holder.getItemViewType() == VIEW_TYPE_HOME){
((homeViewHolder) holder).bind((HomeModel) item);
}
}
