2.RecyclerView中六種item類型:

　　橫幅廣告  頻道 活動 秒殺 推薦 熱賣

3.橫幅廣告 

　　Banner實現輪播

4.秒殺

HomeRecyclerViewAdapter中

public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {    .....    } else if (viewType == SECKILL) {        return new SeckillViewHolder(mLayoutInflater.inflate(R.layout.seckill_item, null), mContext);    }}

SeckillViewHolder　　

class SeckillViewHolder extends RecyclerView.ViewHolder {    private TextView tvMore;    private RecyclerView recyclerView;    public Context mContext;    public SeckillViewHolder(View itemView, Context mContext) {        super(itemView);        tvTime = (TextView) itemView.findViewById(R.id.tv_time_seckill);        tvMore = (TextView) itemView.findViewById(R.id.tv_more_seckill);        recyclerView = (RecyclerView) itemView.findViewById(R.id.rv_seckill);        this.mContext = mContext;    }    public void setData(final ResultBean.SeckillInfoBean data) {        //設定時間        if (isFirst) {//                dt = (int) (Integer.parseInt(data.getEnd_time()) - System.currentTimeMillis());            dt = (int) (Integer.parseInt(data.getEnd_time()) - (Integer.parseInt(data.getStart_time())));            isFirst = false;        }        //設定RecyclerView        recyclerView.setLayoutManager(new LinearLayoutManager(mContext, LinearLayoutManager.HORIZONTAL, false));        SeckillRecyclerViewAdapter adapter = new SeckillRecyclerViewAdapter(mContext, data);        recyclerView.setAdapter(adapter);        //倒計時        handler.sendEmptyMessageDelayed(0, 1000);        //點擊事件        adapter.setOnSeckillRecyclerView(new SeckillRecyclerViewAdapter.OnSeckillRecyclerView() {            @Override            public void onClick(int position) {                ResultBean.SeckillInfoBean.ListBean listBean = data.getList().get(position);                String name = listBean.getName();                String cover_price = listBean.getCover_price();                String figure = listBean.getFigure();                String product_id = listBean.getProduct_id();                GoodsBean goodsBean = new GoodsBean(name, cover_price, figure, product_id);//                Intent intent = new Intent(mContext, GoodsInfoActivity.class);                intent.putExtra(GOODS_BEAN, goodsBean);                mContext.startActivity(intent);                // Toast.makeText(mContext, "position:" + position, Toast.LENGTH_SHORT).show();            }        });    }}

　　

private boolean isFirst = true;    private TextView tvTime;    private int dt;    private Handler handler = new Handler() {        @Override        public void handleMessage(Message msg) {            if (msg.what == 0) {                dt = dt - 1000;                SimpleDateFormat sd = new SimpleDateFormat("HH:mm:ss");                tvTime.setText(sd.format(new Date(dt)));                handler.removeMessages(0);                handler.sendEmptyMessageDelayed(0, 1000);                if (dt == 0) {                    handler.removeMessages(0);                }            }        }    };

採用CountdownView實現秒殺倒計時的效果
