一、原理介绍

1、打开大众点评app商店

    public void open_shop(Context context,String shop_id)
    {
        String url="dianping://gcshopshell?shopuuid="+shop_id;
        scroll_count=0;
        Uri uri = Uri.parse(url); //
        Intent intent =new Intent(Intent.ACTION_VIEW,uri);;
        intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        context.startActivity(intent);
    }

2、采集如下字段：

    public class Commodity{
        public int id;
        public String title;        //商品标题
        public String price;      //售价
        public String market_price;  //市场价
        public String sales;            //年销量
        public String shop_id;        //商店id
        public String shop_index;
        public int count;
    }

3、 保存数据为Csv文件

            Csv csv1=Csv.getInstance(context);
            boolean bres=csv1.save_commodities(commodities);
            if(bres==false){
                fb.set_show("保存数据失败！请检查有没有数据存储权限！");
                return;
            }

4、滚动屏幕

private void performScroll(AccessibilityNodeInfo rootNode){
        if(mCurrentUI.startsWith("com.dianping.shopshell")){
            AccessibilityNodeInfo scrollNode=AccessibilityHelper.findNodeInfosById(rootNode,"com.dianping.v1:id/pagecontainer_recyclerview",0);
            if(scrollNode!=null) {
                if (scroll_count < 10) {
                    AccessibilityHelper.performScrollForward(scrollNode);
                    AccessibilityNodeInfo firstNode=AccessibilityHelper.findNodeInfoByTextAllMatched(rootNode,"抢购");
                    if(firstNode==null)scroll_count=10;
                }
                else {
                    AccessibilityHelper.performScrollBackward(scrollNode);
                    AccessibilityNodeInfo firstNode=AccessibilityHelper.findNodeInfoByTextAllMatched(rootNode,"封面");
                    if(firstNode!=null)scroll_count=0;
                }
                scroll_count += 1;
                if (scroll_count > 20) {
                    scroll_count = 0;
                }
            }
            //AccessibilityNodeInfo no_moreNode=AccessibilityHelper.findNodeInfosByText(rootNode,"收起",0);
            

        }

5、采集数据

private Commodity get_commodity(AccessibilityNodeInfo buyNode){
        try{
            AccessibilityNodeInfo parent=buyNode.getParent();
            if(parent==null)return null;
            parent=parent.getParent();
            if(parent==null)return null;
            int price_count=0;
            Commodity commodity=new Commodity();
            for (int i = 0; i < parent.getChildCount(); i++) {
                AccessibilityNodeInfo child=parent.getChild(i);
                if(child!=null&&child.getText()!=null){
                    String text=child.getText().toString();
                    text=text.replaceAll(",","[comma]");
                    commodity.shop_id=shop_id;
                    commodity.shop_index=String.valueOf(csv.shop_index);
                    commodity.count=commodity_count;
                    if(i==0){
                        //if(isInCommodities(text))return null;
                        commodity.title=text;
                    }
                    if(text.startsWith("年售"))commodity.sales=text;
                    if(text.startsWith("全国爆卖"))commodity.sales=text;
                    if(text.startsWith("¥")){
                        if(price_count==0)
                            commodity.price=text;
                        else
                        if(price_count==1)
                            commodity.market_price=text;
                        price_count+=1;
                    }

                }
            }
            if(isInCommodities(commodity))return null;
            return commodity;
        }catch
