解析JSON对象（lat和液化天然气）的GoogleMap的作为标记 [英] Parse JSON objects(lat and lng) in GoogleMap as markers

问题描述

当我分析的纬度和经度的的System.out.println（shop.getShopLat（））; 的正常工作。而如果没有标记的地图工作正常。现在，我想添加使用shop.getShopLat（）和shop.getShopLng（）几个标记。但是，当我试图实现这个越来越redflags：构造经纬度（ArrayList中，ArrayList中）未定义有人请帮助解决这个

When I parse the lat and lng in System.out.println(shop.getShopLat()); works fine. And the Map without marker works fine. Now I want to add several marker using shop.getShopLat() and shop.getShopLng(). But when I tried to implement this getting redflags: The constructor LatLng(ArrayList, ArrayList) is undefined Someone please help to solve this?

推荐答案

请看看这一行：

for(Shop shop : this.response.shops){
            map.addMarker(new MarkerOptions().position(new LatLng(shop.getShopLat(), shop.getShopLng())).title(shop.getShopAddress()));
            }

在这一行要通过添加构造成一个阵列，而不是一个值来创建一个新的经纬度（）对象，此行变成：

In this line you want to create a new LatLng() object by adding into constructor an array instead of one value, change this line into:

for(Shop shop : this.response.shops){
    //remember to check is shop.getShopLat() is not null etc..
    for(int i = 0; i < shop.getShopLat().size(); i++){
        map.addMarker(new MarkerOptions().position(new LatLng( shop.getShopLat().get(i), shop.getShopLng().get(i) )).title( shop.getShopAddress().get(i) ));
    }
}
