Answer 1

public class Bean{
private String currentCity;
private String pm25;

get和set方法

}

public static Bean getBean(){
//省略

    if(json.has("results")){
        JSONArray array = json.getjsonArray("result");
        String arrayStr = array.toString();

        Bean bean = new Bean();
        Gson gson = new GsonBuilder().create();
        bean = gson.fromJson(arrayStr,
                        new TypeToken<ArrayList<Bean>>() {
                        }.getType());
                return bean;
    }

}
