Question

Trying to parse the following json using gson in my android app but givien it’s structure can’t work it out.

JSON

[
{
    "city": {
        "country": "Canada",
        "id": 1,
        "name": "Toronto",
        "province": "Ontario"
    }
},
{
    "city": {
        "country": "Canada",
        "id": 11,
        "name": "Ajax",
        "province": "Ontario"
    }
}
]

JAVA

public class LocationCityList {

    private List<LocationCityContainer> cities;


    public List<LocationCityContainer> getTrends() {
        return cities;
    }
    public void setTrends(List<LocationCityContainer> cities) {
        this.cities = cities;
    }

}

The following returns an array of proper length but after that I can’t work out how to get city objects themselves.

Gson gson = new Gson();
Reader r = new InputStreamReader(getJSONData(url));       
LocationCityList[] objs = gson.fromJson(r, LocationCityList[].class);

Any help much appreciated.

Answer 1

OK figured it out. Java code needs to be as follows.

public class LocationCityList {

LocationCity city;

public LocationCity getLocationCity(){
    return city;
}   

}

public class LocationCity {
private String name;
private String id;

public String getName() {
    return name;
}
public void setName(String name) {
    this.name = name;
}
public String getId() {
    return id;
}
public void setId(String id) {
    this.id = id;
}

}
