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
前端UI跟之前差不多
改动点1
改动了API，当然要重新写GSON
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ListView
private List<ForecastData> dataList = new ArrayList<>(); // 预报列表
private ForecastAdapter adapter; // 预报适配器
@Override
protected 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() {
@Override
public void onClick(View view) {
Intent intent = new Intent(MainActivity.this, SelectCityActivity.class);
startActivityForResult(intent, 1001);
}
});
}
@Override
protected 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() {
@Override
public void onResponse(Call call, final Response response) throws IOException {
runOnUiThread(new Runnable() {
@Override
public 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();
}
}
});
}
@Override
public 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

SelectCityActivity实现列表展示
public class SelectCityActivity extends AppCompatActivity {
private ListView lvCityList;
private ArrayAdapter<String> adapter;
private String[] cityList;
@Override
protected 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() {
@Override
public 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
