Show Section Headers in RecyclerView

• Quick Code :

@Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        int steps = 0;
        for (int i = 0; i < sections.size(); i++) {
            Pair<String, String[]> section = sections.get(i);
            if(steps == position) {
                ((HeaderHolder) holder).getView().setText(section.first);
                return;
            }
            steps++;

            for (int j = 0; j < section.second.length; j++) {
                if(steps == position) {
                    ((ItemHolder) holder).getView().setText(section.second[j]);
                    return;
                }
                steps++;
            }
        }
    }

• Use the getItemViewType(int position) override to specify different view types
• Use differently styled ViewHolders in the onBindViewHolder override
• In this example ,we have a header viewType and an item viewType
• The layout for the header viewtype ViewHolder is styled with a blueish background to highlight it
• You can add in more customized headers and item layouts, this example is just making a point.
