[Android] correspondence case study notes between the activity of the high moral map to achieve Weather inquiry

[Overview] app realize the weather is normal query function, and also because often more than one activity to acquire data, then think of a class package, to call to get to when needed.

[High] De api address https://lbs.amap.com/api/android-sdk/guide/map-data/weather

[Note] because a little ignorant to see the document, it will catch his next record brain to write code to query

[Thinking] activity sends a request - get the address - the address to obtain weather - callback to the activity

1, to obtain the current city or region

Because the documentation is provided directly location query, so first get to the site, uses GPSUtils class (see Last Blog: https://blog.csdn.net/gzyh_tech/article/details/82491214 ).

mquery = new WeatherSearchQuery("北京", WeatherSearchQuery.WEATHER_TYPE_LIVE);

2, along with the feeling of high moral document to go, you can smooth access to weather data.

3. The focus is on the activity of communication.

Method page1 interfaces define a static properties:

 //  查询天气回调
    public interface Event {
        public void setWeather(String weather,String city,String tem);
    }
    public static class EventManager {
        private static Event mEvent;

        public static void setEventListener(Event nm) {
            mEvent = nm;
        }

        public static void raiseEvent(String weather,String city,String tem) {
            mEvent.setWeather(weather,city,tem);
        }
    }
    // 查询天气回调


    private Event event = new Event() {
        @Override
        public void setWeather(String weather,String city,String tem) {
            id_address.setText(city);
            Toast.makeText(getActivity(),city+",天气："+weather+",温度："+tem,Toast.LENGTH_SHORT).show();
        }
    };

page2 after the call to return to get the data:

weatherFragment.EventManager.raiseEvent(weather,address,temperature);
