i am trying to switch setLayoutManager between LinearLayoutManager(List) to GridLayoutManager(GridView) on toggle button it is working fine but when the layout changes for list to grid its giving me an exception in list view i am showing extra data than girdView and setting texts cant not find this Textviews in gridView single item file so its giving me an error can you please guide how can i handle two layouts and views in single Adapter
this is my Adapter Code
public class SavedAlbumAdapter2 extends RecyclerView.Adapter<SavedAlbumAdapter2.ItemViewHolder> {
private final GlideRequest<Drawable> request;
private ArrayList<AlbumLocalObj> itemModels;
private static final int LIST_ITEM = 0;
private static final int GRID_ITEM = 1;
private ClickListener mListener;
private LocalPreferences localPreferences;
public SavedAlbumAdapter2(Activity context, ArrayList<AlbumLocalObj> values, ClickListener clickListener) {
itemModels = values;
this.mListener = clickListener;
localPreferences = new LocalPreferences(context);
int reqWidth = ((HomeActivity) context).screenWidth / 2;
request = GlideApp.with(context)
.asDrawable()
.centerCrop()
.override(reqWidth, reqWidth)
.transition(withNoTransition());
}
@Override
public ItemViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View itemView;

itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_gallery2, parent, false);
} else {
itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.list_item_gallery, parent, false);
}
return new ItemViewHolder(itemView, mListener);
}
@Override

AlbumLocalObj model = itemModels.get(position);
holder.img_label.setText(model.getName());
holder.tv_count.setText(String.valueOf(model.getCount()));
initializeViews(model, holder, position);
}
@Override
public int getItemViewType(int position) {
if (localPreferences.isGridViewEnabled()) {
return GRID_ITEM;
} else {
return LIST_ITEM;
}
}
private void initializeViews(AlbumLocalObj model, final ItemViewHolder holder, int position) {
if (model.getMediaFileObject() == null)
holder.gallery_img.setImageResource(R.drawable.ic_empty_fol);
else {
request.load(model.getMediaFileObject()).listener(new RequestListener<Drawable>() {

}
} catch (Exception e) {

}
}
@Override

return itemModels.size();
}
public static class ItemViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener, View.OnLongClickListener {
SquarImageView gallery_img;

TextView tv_count;
ImageButton info;
private ClickListener mListener;
ItemViewHolder(View itemView, ClickListener listener) {
super(itemView);

}

this is my layout for single item of grid View
