Android——Retrofit工具类封装

导依赖

	implementation 'com.squareup.retrofit2:retrofit:2.0.0'
    implementation 'com.squareup.retrofit2:converter-gson:2.0.2'

创建类

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 Retrofit retrofit;

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

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