1.添加依赖

    implementation 'com.squareup.okhttp3:okhttp:3.2.0'
    implementation 'com.squareup.okio:okio:1.7.0'
    implementation 'com.squareup.okhttp3:logging-interceptor:3.4.1'
    implementation 'com.squareup.retrofit2:retrofit:2.0.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.0.2'

2.封装工具类

public class RetrofitUtils {
    private static RetrofitUtils retrofitUtils;
    private RetrofitUtils(){}

    public static RetrofitUtils getInstance(){
        if (retrofitUtils==null){
            synchronized (RetrofitUtils.class){
                if (retrofitUtils==null){
                    retrofitUtils=new RetrofitUtils();
                }
            }
        }
        return retrofitUtils;
    }

    private static OkHttpClient okHttpClient;

    private static synchronized OkHttpClient getOkHttpClient() {
        final HttpLoggingInterceptor loggingInterceptor = new HttpLoggingInterceptor(new HttpLoggingInterceptor.Logger() {
            @Override
            public void log(String message) {
                Log.i("xxx",message);
            }
        });
        loggingInterceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        okHttpClient = new OkHttpClient.Builder()
                .addInterceptor(loggingInterceptor)
                .addInterceptor(new Interceptor() {
                    @Override
                    public Response intercept(Chain chain) throws IOException {
                        Request request = chain.request()
                                .newBuilder()
                                .addHeader("userId", "11249")
                                .addHeader("sessionId", "155056366467311249")
                                .build();
                        return chain.proceed(request);
                    }
                })

                .build();
        return okHttpClient;
    }

    private static Retrofit retrofit;

    public static synchronized Retrofit getRetrofit(String ShowUrl){
        retrofit=new Retrofit.Builder()
                .baseUrl(ShowUrl)
                .addConverterFactory(GsonConverterFactory.create())
                .client(getOkHttpClient())
                .build();

        return retrofit;
    }

    public <T>  T getApiService(String ShowUrl,Class<T> service){
        Retrofit retrofit=getRetrofit(ShowUrl);
        T t=retrofit.create(service);
        return t;
    }
}
