Android-obtain weather information and download the source code based on Webservice (3)

This project is described as follows:
1. You can obtain service information in three ways. Soap, http get, and http post are used to obtain information.
2. Detailed steps for webservice calling Based on android
 

As described in the previous blog post, the province list and city list both use the Adapter class. The Code is as follows:

public class ProviceOrCityAdapter extends BaseAdapter {    private ArrayList
  
    arrayList;    private Context context;    public ProviceOrCityAdapter(Context context,ArrayList
   
     arrayList){        this.context = context;        this.arrayList = arrayList;    }    @Override    public int getCount() {        return arrayList.size();    }    @Override    public Object getItem(int position) {        return arrayList.get(position);    }    @Override    public long getItemId(int position) {        return position;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        Holder holder;        if (convertView == null) {            convertView = View.inflate(context, R.layout.main_list_item, null);            holder = new Holder();            holder.text = (TextView) convertView.findViewById(R.id.provice_tx);            convertView.setTag(holder);        }else {            holder = (Holder) convertView.getTag();        }        holder.text.setText(arrayList.get(position));        return convertView;    }    class Holder{        TextView text;    }}
   
  

The Adapter class is very simple, that is, to save a text. In fact, BaseAdapter is not used at all. You can try ListAdapter class.
The following code lists cities and counties:

Public class CityListActivity extends Activity {private ListView cityList; private TextView backTx; private ArrayList
  
   
CityArrayList = new ArrayList <> (); private ProviceOrCityAdapter adapter; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); requestWindowFeature (Window. FEATURE_NO_TITLE); setContentView (R. layout. city_activity_listv); init (); setClick (); // obtain the city list through http get // HttpUtils. getCityGet (getIntent (). getStringExtra (provice); // obtain the city list in http post mode // HttpUtils. getCityPost (getIntent (). getStringExtra (provice); final WebServiceUtil webServiceUtil = new WebServiceUtil (); webServiceUtil. setCityCallBack (new CallBack () {@ Override public void getData (ArrayList
   
    
ArrayList) {CityListActivity. this. cityArrayList = arrayList; adapter = new ProviceOrCityAdapter (CityListActivity. this, arrayList); cityList. setAdapter (adapter) ;}}, getIntent (). getStringExtra (provice);} private void setClick () {backTx. setOnClickListener (new OnClickListener () {@ Override public void onClick (View v) {finish () ;}}); cityList. setOnItemClickListener (new OnItemClickListener () {@ Override public void onItemClick (AdapterView
    Parent, View view, int position, long id) {Toast. makeText (CityListActivity. this, cityArrayList. get (position), Toast. LENGTH_SHORT ). show (); Intent intent = new Intent (CityListActivity. this, WeatherActivity. class); intent. putExtra (theRedionCode, getIntent (). getStringExtra (provice); startActivity (intent) ;}});} private void init () {cityList = (ListView) findViewById (R. id. city_list); backTx = (TextView) findViewById (R. id. back); adapter = new ProviceOrCityAdapter (CityListActivity. this, cityArrayList); cityList. setAdapter (adapter) ;}@ Override protected void onDestroy () {super. onDestroy ();}}
   
  

It's not hard to explain.
The following is how to obtain WeatherActivity weather information:
The Code is as follows:

Public class WeatherActivity extends Activity {private TextView back; private TextView weatherTx; @ Override protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); requestWindowFeature (Window. FEATURE_NO_TITLE); setContentView (R. layout. weather_activity_view); init (); setclick (); // GET weather information GET method // HttpUtils. getWeatherGet (getIntent (). getStringExtra (theRedionCode); // obtain the weather information POST method // HttpUtils. getWeatherPost (getIntent (). getStringExtra (theRedionCode); final WebServiceUtil webServiceUtil = new WebServiceUtil (); webServiceUtil. setWeatherCallBack (new WeatherCallBack () {@ Override public void getData (String weather) {weatherTx. setText (weather) ;}}, getIntent (). getStringExtra (theRedionCode);} private void setclick () {back. setOnClickListener (new OnClickListener () {@ Override public void onClick (View v) {finish () ;}});} private void init () {back = (TextView) findViewById (R. id. back); weatherTx = (TextView) findViewById (R. id. text );}}

I am a lazy here, just getting the weather information and displaying it in text.
This project implements three methods to obtain data, but does not describe how to obtain data in three ways. The following shows the code for obtaining data using http get and http post:

Public class HttpUtils {private static String TAG = HttpUtils. class. getSimpleName ();/*** obtain province * post method */public static void GetProvicePost () {Log.

This class enables network access to weather information data. You may ask, this class does not parse the data, but simply prints the obtained data? In fact, the obtained data is the same as the first soap method.
