要实现Android接收天气警报触发器的API,你可以使用一些天气数据提供商的API,例如OpenWeatherMap、Weather.com等。以下是使用OpenWeatherMap API的示例代码:
implementation 'com.squareup.okhttp3:okhttp:4.9.1'
implementation 'com.google.code.gson:gson:2.8.7'
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import com.google.gson.Gson;
import com.squareup.okhttp.Call;
import com.squareup.okhttp.Callback;
import com.squareup.okhttp.OkHttpClient;
import com.squareup.okhttp.Request;
import com.squareup.okhttp.Response;
import java.io.IOException;
public class WeatherAlertTrigger extends BroadcastReceiver {
private static final String TAG = "WeatherAlertTrigger";
@Override
public void onReceive(Context context, Intent intent) {
// 在这里处理接收天气警报的逻辑
String apiKey = "YOUR_API_KEY";
String city = "YOUR_CITY";
OkHttpClient client = new OkHttpClient();
String url = "https://api.openweathermap.org/data/2.5/weather?q=" + city + "&appid=" + apiKey;
Request request = new Request.Builder()
.url(url)
.build();
Call call = client.newCall(request);
call.enqueue(new Callback() {
@Override
public void onFailure(Request request, IOException e) {
Log.e(TAG, "请求失败:" + e.getMessage());
}
@Override
public void onResponse(Response response) throws IOException {
if (response.isSuccessful()) {
String json = response.body().string();
WeatherData weatherData = new Gson().fromJson(json, WeatherData.class);
// 在这里判断天气条件,根据需要触发警报
if (weatherData.getMain().getTemp() > 30) {
Log.d(TAG, "天气热,触发警报");
} else {
Log.d(TAG, "天气正常");
}
}
}
});
}
}
public class WeatherData {
private MainData main;
public MainData getMain() {
return main;
}
public void setMain(MainData main) {
this.main = main;
}
public class MainData {
private double temp;
public double getTemp() {
return temp;
}
public void setTemp(double temp) {
this.temp = temp;
}
}
}
请注意,上述代码中的YOUR_API_KEY
和YOUR_CITY
需要替换为你自己的OpenWeatherMap API密钥和城市名称。
以上就是一个简单的Android接收天气警报触发器的示例代码。你可以根据自己的需求进行修改和扩展。
