ViewFinder

Just use the ViewFinder instead of any ViewHolder;
No more need to create a ViewHolder each time in your project;
The ViewFinder has the same features as a ViewHolder;
The ViewFinder can dynamically provide any link to any view;
So you can easily add a new view type to your list.

In few words: The ViewHolder has one function - to provide a link to the view in a layout. So when you use the RecyclerView and you need to add a new View Type in your list - you must create a new ViewHolder. It is fine when you have a couple types. But there is no need to create each time a new Holder. With this library you no need create a ViewHolder each time. The ViewFinder as a universal ViewHolder. It can provide a link to anyone view.

Example

import com.github.vivchar.viewfinder.ViewHolder;

public class YourAdapter extends RecyclerView.Adapter<ViewHolder> {

    @Override
    public ViewFinder onCreateViewHolder(final ViewGroup parent, final int viewType) {
        return new ViewFinder(LayoutInflater.from(mContext).inflate(getLayoutID(viewType), parent, false));
    }

    @Override
    public void onBindViewHolder(final ViewHolder viewHolder, final int position) {
        final BaseItem item = mItems.get(position);

        if (item instanceof YourItem) {
            YourItem yourItem = (YourItem)item;
        
            final SwitchCompat switchCompat = viewHolder.find(R.id.item_switch);

            viewHolder.getViewFinder()
                .find(R.id.custom_view, (ViewProvider<CustomView>) view -> {
                    ... 
                })
                .setText(R.id.item_name, yourItem.getName())
                .setBackgroundResource(R.id.item_logo, yourItem.getLogoResource())
                .setOnClickListener(v -> {
                    switchCompat.setChecked(!switchCompat.isChecked());
                    mListener.onItemClicked(yourItem);
                }));
        } else if (item instanceof OtherItem) {
            //No need to create new ViewHolder, you just use the ViewFinder again
            //See onCreateViewHolder() method, it has only one ViewHolder 
            viewHolder.getViewFinder()
                .find(...)
                .setVisible(...)
                .setText(...);
        }
    }
    
    private int getLayoutID(int viewType) {
        if (viewType == YOUR_TYPE) {
            return R.layout.your_item;
        } else if (...) {
            return R.layout.other_item;
        } else if (...) {
            //...
        }
    }

    //...

}
