Android简单版天气预报源码，整体重构（第四步）

Android简单版天气预报源码，整体重构（第四步）

找到一个比较好用的天气数据API

http://wthrcdn.etouch.cn/weather_mini?city=深圳
http://wthrcdn.etouch.cn/weather_mini?citykey=101280601

• 这两个都可以 我选择了第一个进行更新，不用之前的的心知天气API了

快春节了，更新一下，说是第四步，也不是哈哈哈哈

项目源码地址
https://github.com/LGH-cmd/weather-report
或：https://gitee.com/lin_g_g_hui/weather-report

前端UI跟之前差不多

改动点1

改动了API，当然要重新写GSON

• 可以参考前面实现的

也就依葫芦画瓢，就不展示了
MainActivity 大部分实现也就是得到数据后展示到页面

整体代码

public class MainActivity extends AppCompatActivity {private static final String TAG = "MainActivity";private TextView tvTitleName; // 城市名称private TextView tvNowDate; // 今天的日期private TextView tvNowTemp; // 今天的温度private TextView tvNowType; // 今天的天气类型private TextView tvNowWind; // 今天的风向private TextView tvNowGanmao; // 今天的提示private Button SwitchCity; // 切换其他城市private ListView lvForecast ; // 预报ListViewprivate List<ForecastData> dataList = new ArrayList<>(); // 预报列表private ForecastAdapter adapter; // 预报适配器@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);tvTitleName = findViewById(R.id.tv_title_name);tvNowDate = findViewById(R.id.tv_now_date);tvNowTemp = findViewById(R.id.tv_now_temp);tvNowType = findViewById(R.id.tv_now_type);tvNowWind = findViewById(R.id.tv_now_wind);tvNowGanmao = findViewById(R.id.tv_now_ganmao);SwitchCity = findViewById(R.id.btn_switch_city);lvForecast = findViewById(R.id.lv_forecast_content);GetDataAndShowData("深圳");// 选择其他城市SwitchCity.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View view) {Intent intent = new Intent(MainActivity.this, SelectCityActivity.class);startActivityForResult(intent, 1001);}});}@Overrideprotected void onActivityResult(int requestCode, int resultCode, @Nullable Intent data) {if(requestCode == 1001 && resultCode == 1002) {String cityName = data.getStringExtra("cityName");GetDataAndShowData(cityName);}}private void GetDataAndShowData(String cityName) {ProgressDialogUtil.showProgressDialog(MainActivity.this); // 加载框String address = "http://wthrcdn.etouch.cn/weather_mini?city="+cityName;DataUtil.sendOkHttpRequest(address, new Callback() {@Overridepublic void onResponse(Call call, final Response response) throws IOException {runOnUiThread(new Runnable() {@Overridepublic void run() {try {WeatherResponse weatherData = DataUtil.getWeatherData(response.body().string());String cityName = weatherData.getData().getCity(); // 城市名称tvTitleName.setText(cityName);String wendu = weatherData.getData().getWendu(); // 今天的温度tvNowTemp.setText(wendu+"℃");String ganmao = weatherData.getData().getGanmao(); // 今天的提示tvNowGanmao.setText(ganmao);List<Forecast> forecast = weatherData.getData().getForecast(); // 天气信息ForecastData nowData = setNowWeatherData(forecast); // 今天的天气信息// 设置其他日期的信息// 昨天Yesterday yesterday = weatherData.getData().getYesterday();ForecastData yesterdayData = setYesterdayWeatherData(yesterday);// 未来几天ForecastData futureOne = setOtherDayWeatherData(forecast.get(1));ForecastData futureTwo = setOtherDayWeatherData(forecast.get(2));ForecastData futureThree = setOtherDayWeatherData(forecast.get(3));ForecastData futureFour = setOtherDayWeatherData(forecast.get(4));if(dataList.size()!=0) {dataList.clear(); // 清除请一次的数据}dataList.add(yesterdayData);dataList.add(nowData);dataList.add(futureOne);dataList.add(futureTwo);dataList.add(futureThree);dataList.add(futureFour);adapter = new ForecastAdapter(dataList);lvForecast.setAdapter(adapter);ProgressDialogUtil.dismiss(); // 消失加载框} catch (IOException e) {e.printStackTrace();}}});}@Overridepublic void onFailure(Call call, IOException e) {Log.e(TAG, "获得天气出错了" + e);}});}/*** 设置今天的天气信息，返回一个ForecastData，用于在预告中显示* @param forecast* @return*/private ForecastData setNowWeatherData(List<Forecast> forecast) {Forecast forecastNow = forecast.get(0); // 今天的天气信息String nowDate = forecastNow.getDate(); // 今天的日期tvNowDate.setText("今天-"+nowDate);String nowTemp = forecastNow.getHigh(); // 今天的最高温度String nowLow = forecastNow.getLow(); // 今天的最低温度String nowType = forecastNow.getType(); // 今天的天气类型tvNowType.setText(nowType);String nowWind = forecastNow.getFengxiang(); // 今天的风向tvNowWind.setText(nowWind);ForecastData nowData = new ForecastData(nowDate, nowTemp.substring(2), nowLow.substring(2), nowType); // 今天的天气return nowData;}/*** 设置昨天的信息* @param yesterday* @return*/private ForecastData setYesterdayWeatherData(Yesterday yesterday) {String date = yesterday.getDate(); // 昨天的日期String high = yesterday.getHigh(); // 昨天的最高温度String low = yesterday.getLow(); // 昨天的最低温度String type = yesterday.getType(); // 昨天的天气类型ForecastData yesterdayData = new ForecastData(date, high.substring(2), low.substring(2), type); // 昨天的天气return yesterdayData;}/*** 未来几天的天气* @param forecast* @return*/private ForecastData setOtherDayWeatherData(Forecast forecast) {String date = forecast.getDate(); // 未来几天的日期String high = forecast.getHigh(); // 未来几天的最高温度String low = forecast.getLow(); // 未来几天的最低温度String type = forecast.getType(); // 未来几天的天气类型ForecastData otherDayData = new ForecastData(date, high.substring(2), low.substring(2), type); // 未来几天的天气return otherDayData;}}

不同点，在预报中用的是ListView展示
也不是很难实现。与之前有相同之处，可参考前面，完整代码已经在GitHub上

改动点2

将可以选的城市扩充了

在strings.xml写入城市数组

<string-array name="city_list"><item>广州</item><item>番禺</item><item>从化</item><item>增城</item><item>花都</item><item>韶关</item><item>乳源</item><item>始兴</item><item>翁源</item><item>乐昌</item><item>仁化</item><item>南雄</item><item>新丰</item><item>曲江</item><item>浈江</item><item>武江</item><item>惠州</item><item>博罗</item><item>惠阳</item><item>惠东</item><item>龙门</item><item>梅州</item><item>兴宁</item><item>蕉岭</item><item>大埔</item><item>丰顺</item><item>平远</item><item>五华</item><item>梅县</item><item>汕头</item><item>潮阳</item><item>澄海</item><item>南澳</item><item>深圳</item><item>珠海</item><item>斗门</item><item>金湾</item><item>佛山</item><item>顺德</item><item>三水</item><item>南海</item><item>高明</item><item>肇庆</item><item>广宁</item><item>四会</item><item>德庆</item><item>怀集</item><item>封开</item><item>高要</item><item>湛江</item><item>吴川</item><item>雷州</item><item>徐闻</item><item>廉江</item><item>赤坎</item><item>遂溪</item><item>坡头</item><item>霞山</item><item>麻章</item><item>江门</item><item>开平</item><item>新会</item><item>恩平</item><item>台山</item><item>蓬江</item><item>鹤山</item><item>江海</item><item>河源</item><item>紫金</item><item>连平</item><item>和平</item><item>龙川</item><item>东源</item><item>清远</item><item>连南</item><item>连州</item><item>连山</item><item>阳山</item><item>佛冈</item><item>英德</item><item>清新</item><item>云浮</item><item>罗定</item><item>新兴</item><item>郁南</item><item>云安</item><item>潮州</item><item>饶平</item><item>潮安</item><item>东莞</item><item>中山</item><item>阳江</item><item>阳春</item><item>阳东</item><item>阳西</item><item>揭阳</item><item>揭西</item><item>普宁</item><item>惠来</item><item>揭东</item><item>茂名</item><item>高州</item><item>化州</item><item>电白</item><item>信宜</item><item>茂港</item><item>汕尾</item><item>海丰</item><item>陆丰</item><item>陆河</item></string-array>

SelectCityActivity实现列表展示

public class SelectCityActivity extends AppCompatActivity {private ListView lvCityList;private ArrayAdapter<String> adapter;private String[] cityList;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_select_city);lvCityList = findViewById(R.id.lv_city_list);cityList = getResources().getStringArray(R.array.city_list);adapter=new ArrayAdapter<>(SelectCityActivity.this,android.R.layout.simple_list_item_1,cityList);lvCityList.setAdapter(adapter);lvCityList.setOnItemClickListener(new AdapterView.OnItemClickListener() {@Overridepublic void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {String cityName = cityList[i];Toast.makeText(SelectCityActivity.this,cityName,Toast.LENGTH_SHORT).show();Intent intent = new Intent();intent.putExtra("cityName",cityName);setResult(1002, intent);finish();}});}
}

更新了 比之前好多了 后面继续实现其他功能
