RecycleView万能适配器

1.万能适配器：

public abstract class YzpRecycleViewAdapter<T> extends RecyclerView.Adapter<YzpRecycleViewAdapter.VH> {

    private List<T> mData;

    public YzpRecycleViewAdapter(List<T> mData) {
        this.mData = mData;
    }

    public abstract int getLayoutId(int viewType);

    @Override
    public VH onCreateViewHolder(ViewGroup parent, int viewType) {
        return VH.get(parent, getLayoutId(viewType));
    }

    @Override
    public void onBindViewHolder(VH holder, int position) {
        convert(holder, mData.get(position), position);
    }

    @Override
    public int getItemCount() {
        return mData.size();
    }

    public abstract void convert(VH holder, T data, int position);

    public static class VH extends RecyclerView.ViewHolder {
        private SparseArray<View> mViews;
        private View mConvertView;

        private VH(View v) {
            super(v);
            mConvertView = v;
            mViews = new SparseArray<>();
        }

        public static VH get(ViewGroup parent, int layoutId) {
            View convertView = LayoutInflater.from(parent.getContext()).inflate(layoutId, parent, false);
            return new VH(convertView);
        }

        public <T extends View> T getView(int id) {
            View v = mViews.get(id);
            if (v == null) {
                v = mConvertView.findViewById(id);
                mViews.put(id, v);
            }
            return (T) v;
        }

        public void setText(int id, String value) {
            TextView view = getView(id);
            view.setText(value);
        }
    }
}

2.使用万能适配器

private List<Order> list;
private YzpRecycleViewAdapter<Order> adapter;

adapter = new YzpRecycleViewAdapter<Order>(list) {
            @Override
            public int getLayoutId(int viewType) {
                return R.layout.order_item;
            }

            @Override
            public void convert(YzpRecycleViewAdapter.VH holder, Order order, int position) {
                holder.setText(R.id.tv_name, order.getName());
                holder.getView(R.id.tv_name).setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        Toast.makeText(MainActivity.this, order.getName(), Toast.LENGTH_SHORT).show();
                    }
                });
            }
        };
        recycleView.setAdapter(adapter);
        DividerItemDecoration decoration = new DividerItemDecoration(this, DividerItemDecoration.VERTICAL);
        decoration.setDrawable(getResources().getDrawable(R.drawable.divider, null));
        recycleView.addItemDecoration(decoration);
