1.引用：
compile 'com.squareup.retrofit2:retrofit:2.1.0' //retrofit2compile 'com.squareup.retrofit2:converter-gson:2.1.0' //gson适配器compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0' // rxjava适配器compile 'com.squareup.okhttp3:okhttp:3.3.1' //okhttp
2.定义接口类：
public interface WeatherApi { @GET("onebox/weather/query?cityname=深圳") Call<WeatherDataBean> getWeather(@Query("key") String key); @GET("index/") Call<WeatherDataBean> getWeather(@QueryMap Map<String ,String> params );}
3.编写解析类，gsonformat这个插件挺好用的：Mac下快捷键 ： command+N。

4.简单的基本路径和接口定义的拼接 get固定参数使用.
baseurl
Retrofit retrofit=new Retrofit.Builder() .baseUrl("http://gank.io/") .addConverterFactory(GsonConverterFactory.create()) .build();GnakApi gnakApi=retrofit.create(GnakApi.class);Call<GnakBean> call=gnakApi.getAndroidInfo();call.enqueue(new Callback<GnakBean>() { @Override public void onResponse(Call<GnakBean> call, Response<GnakBean> response) { GnakBean.ResultsBean bean=response.body().getResults().get(0); String result="<<"+bean.getImages()+"\n"+bean.getCreatedAt(); Log.i("result",result); Toast.makeText(MainActivity.this,result,Toast.LENGTH_LONG).show(); } @Override public void onFailure(Call<GnakBean> call, Throwable t) { }});
5.get动态参数
Retrofit retrofit1=new Retrofit.Builder() .baseUrl("http://op.juhe.cn/") .addConverterFactory(GsonConverterFactory.create()) .build();WeatherApi weatherApi=retrofit1.create(WeatherApi.class); //124ac971e272bed4354d9c6b9b4e9de2Call<WeatherDataBean> call1=weatherApi.getWeather("124ac971e272bed4354d9c6b9b4e9de2");call1.enqueue(new Callback<WeatherDataBean>() { @Override public void onResponse(Call<WeatherDataBean> call, Response<WeatherDataBean> response) { WeatherDataBean.ResultBean bean=response.body().getResult(); String resultweather=bean.getToday().getTemperature()+"<<"; Log.i("result",resultweather); Toast.makeText(MainActivity.this,resultweather,Toast.LENGTH_LONG).show(); } @Override public void onFailure(Call<WeatherDataBean> call, Throwable t) { }});
6.get参数请求
Retrofit retrofit2=new Retrofit.Builder() .baseUrl("http://gank.io/") .addConverterFactory(GsonConverterFactory.create()) .build();GnakApi gnakApi2=retrofit2.create(GnakApi.class);Call<GnakBean> call2=gnakApi2.getAndroidInfo(10,1);call2.enqueue(new Callback<GnakBean>() { @Override public void onResponse(Call<GnakBean> call, Response<GnakBean> response) { GnakBean.ResultsBean bean=response.body().getResults().get(0); String result="<<"+bean.getImages()+"\n"+bean.getCreatedAt(); Log.i("result",result); Toast.makeText(MainActivity.this,result,Toast.LENGTH_LONG).show(); } @Override public void onFailure(Call<GnakBean> call, Throwable t) { }});
7.Get参数拼接
Retrofit retrofit3=new Retrofit.Builder() .baseUrl("http://v.juhe.cn/weather/") //http://v.juhe.cn/weather/index?format=2& .addConverterFactory(GsonConverterFactory.create()) .build();WeatherApi weatherApi3=retrofit3.create(WeatherApi.class);Map<String ,String> params=new HashMap<>(); params.put("cityname","深圳");params.put("format","1");params.put("key","124ac971e272bed4354d9c6b9b4e9de2");Call<WeatherDataBean> call3=weatherApi3.getWeather(params);call3.enqueue(new Callback<WeatherDataBean>() { @Override public void onResponse(Call<WeatherDataBean> call, Response<WeatherDataBean> response) { if (response.errorBody()==null){ WeatherDataBean.ResultBean bean=response.body().getResult(); String resultweather=bean.getToday().getTemperature()+"<<"; Log.i("result",resultweather); Toast.makeText(MainActivity.this,resultweather,Toast.LENGTH_LONG).show(); }else { Toast.makeText(MainActivity.this,response.errorBody().,Toast.LENGTH_LONG).show(); } } @Override public void onFailure(Call<WeatherDataBean> call, Throwable t) { }});
