写一个简单的RecyclerView用法

private Object[][] data = new Object[][]{
            {"绘制三角形", TriangleActivity.class.getName()}
    };

RecyclerView recyclerView = findViewById(R.id.recycler_view);
LinearLayoutManager linearLayoutManager = new LinearLayoutManager(MainActivity.this, LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(linearLayoutManager);
recyclerView.addItemDecoration(new DividerItemDecoration(MainActivity.this, LinearLayout.VERTICAL));
recyclerView.setAdapter(new CustomAdapter(MainActivity.this, data));

private class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder> {
        private Context mContext;
        private Object[][] data;

        public CustomAdapter(Context context, Object[][] data) {
            this.mContext = context;
            this.data = data;
        }

        public class ViewHolder extends RecyclerView.ViewHolder {
            private TextView textView;
            private View itemView;

            public ViewHolder(View itemView) {
                super(itemView);
                textView = itemView.findViewById(android.R.id.text1);
                this.itemView = itemView;
            }
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            return new ViewHolder(LayoutInflater.from(mContext).inflate(android.R.layout.simple_list_item_1, null));
        }

        @Override
        public void onBindViewHolder(final ViewHolder holder, int position) {
            holder.textView.setText(data[position][0].toString());
            holder.itemView.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    String clzName = data[holder.getAdapterPosition()][1].toString();
                    try {
                        Class clz = Class.forName(clzName);
                        mContext.startActivity(new Intent(mContext, clz));
                    } catch (ClassNotFoundException e) {
                        e.printStackTrace();
                    }
                }
            });
        }

        @Override
        public int getItemCount() {
            return data.length;
        }

    }
