Gradle设置

compile 'com.squareup.retrofit2:retrofit:2.2.0'compile 'com.squareup.retrofit2:converter-gson:2.0.2'1，定义beanpublic class RepositoryBean {    String full_name;    String html_url;    int contributions;    @Override    public String toString() {        return full_name + " (" + contributions + ")";    }}

2,定义接口类

public interface GitHubService {    @GET("orgs/{orgName}/repos")    Call<List<RepositoryBean>> queryOrgRepos(            @Path("orgName") String orgName);    Retrofit retrofit = new Retrofit.Builder()            .baseUrl("https://api.github.com/")            .addConverterFactory(GsonConverterFactory.create())            .build();}

3,调用
