基于Androidstudio推荐一个简易的天气预报app源码

以下是一个简单的天气预报应用程序的Android Studio源代码示例，您可以根据需要进行修改：

public class MainActivity extends AppCompatActivity {
    private TextView cityText;
    private TextView condDescr;
    private TextView temp;
    private TextView press;
    private TextView windSpeed;
    private TextView windDeg;
    private TextView hum;
    private ImageView imgView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        cityText = (TextView) findViewById(R.id.cityText);
        condDescr = (TextView) findViewById(R.id.condDescr);
        temp = (TextView) findViewById(R.id.temp);
        hum = (TextView) findViewById(R.id.hum);
        press = (TextView) findViewById(R.id.press);
        windSpeed = (TextView) findViewById(R.id.windSpeed);
        windDeg = (TextView) findViewById(R.id.windDeg);
        imgView = (ImageView) findViewById(R.id.condIcon);

        String city = "London,UK";
        String key = "your_api_key";
        String url = "http://api.openweathermap.org/data/2.5/weather?q=" + city + "&appid=" + key;

        new WeatherTask().execute(url);
    }

    private class WeatherTask extends AsyncTask<String, Void, Weather> {
        @Override
        protected Weather doInBackground(String... params) {
            String data = ((new WeatherHttpClient()).getWeatherData(params[0]));
            Weather weather = JSONWeatherParser.getWeather(data);
            return weather;
        }

        @Override
        protected void onPostExecute(Weather weather) {
            super.onPostExecute(weather);

            if (weather != null) {
                cityText.setText(weather.location.getCity() + "," + weather.location.getCountry());
                temp.setText("" + Math.round((weather.temperature.getTemp() - 273.15)) + "°C");
                hum.setText("" + weather.currentCondition.getHumidity() + "%");
                press.setText("" + weather.currentCondition.getPressure() + " hPa");
                windSpeed.setText("" + weather.wind.getSpeed() + " m/s");
                windDeg.setText("" + weather.wind.getDeg() + "°");
                condDescr.setText(weather.currentCondition.getCondition() + "(" + weather.currentCondition.getDescr() + ")");

                Picasso.with(MainActivity.this).load(weather.currentCondition.getIconURL()).into(imgView);
            }
        }
    }
}

请注意，在上述代码示例中，您需要使用自己的API密钥，您可以从OpenWeatherMap网站上获得。另外，您需要在布局文件中定义必要的TextView和ImageView元素，以便在代码中引用它们。
