不多BB,直接上代码!
①项目准备
compile 'io.reactivex.rxjava2:rxjava:2.0.0'
compile 'io.reactivex.rxjava2:rxandroid:2.0.0'
compile 'org.reactivestreams:reactive-streams:1.0.0'
compile'com.squareup.okhttp3:okhttp:3.4.1'
compile 'com.squareup.okio:okio:1.10.0'
compile 'com.squareup.retrofit2:retrofit:2.1.0'
compile 'com.jakewharton.retrofit:retrofit2-rxjava2-adapter:1.0.0'
compile 'com.squareup.retrofit2:converter-gson:2.1.0'
②项目结构
一个主体类MainActivity,接口WeathearService,Bean类Weather
(上面拼单词的时候...weather拼成weathear...英语水平不够,见谅。。。)
③接口类
public interface WeathearService {
@GET("x3/weather") Flowable<Weather> getWeather(
@Query("city")String city, @Query("key")String keyName);
}
//get请求方式, Flowable<Weather> 记住这里传入的是你的Bean类(Weather)
//x3/weather 是基本url后面拼接的字符串
// @Query("city")String city 代表的意思是URL后面携带的参数city=传入的城市,key则是你申请到的一个密钥值
④主体类
Retrofit retrofit = new Retrofit.Builder()
.baseUrl("https://api.heweather.com/")
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())// 添加RxJava2的适配器支持 必须要加。
.addConverterFactory(GsonConverterFactory.create())
.build();mWeathearService = retrofit.create(WeathearService.class);
//初始化Retrofit
// addCallAdapyerFactory 是创建了第三方库封装好的adapter
private void initUI() {
mTextView = (TextView) findViewById(R.id.weather);
findViewById(R.id.btn).setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
mWeathearService.getWeather("广州", "---你申请到的key值--")//网络请求在子线程
.subscribeOn(Schedulers.io())订阅者要在主线程执行
.observeOn(AndroidSchedulers.mainThread())
.subscribe(new Subscriber<Weather>() {
@Override
public void onSubscribe(Subscription s) {
//请求次数,设置最大值即可
s.request(Long.MAX_VALUE);
}
@Override
public void onNext(Weather weather) {
String s = weather.result.get(0).aqi.city.toString();
Log.i("sea", "weather:" + s);
mTextView.setText(s); }
@Override
public void onError(Throwable t) {
//当网络请求出错会执行这里
Log.i("sea", t.getMessage());
}
@Override
public void onComplete() {
//执行这里全部操作结束
Log.i("sea", "获取结束");
}
});
}
});
}
⑤bean类(比较长,重点理解在实体类和接口类)
public class Weather {
@SerializedName("HeWeather data service 3.0")//json数据头的替换
public ArrayList<Result> result;
/***信息的全部内容*/
public class Result{
public Aqi aqi;
public CityBasic basic;
public Now now;
public ArrayList<Daily> daily_forecast;
public ArrayList<Hourly> hourly_forecast;
public String status;
public Suggestion suggestion;

public class CityBasic{

return "CityBasic{" +
"city='" + city + '\'' +

}
public String city;//城市名称
