Retrofit2简单使用初试用

package com.example.gsc.xinkongjian;import android.app.Activity;import android.os.Bundle;import android.util.Log;import android.view.View;import android.widget.TextView;import com.squareup.okhttp.ResponseBody;import java.io.IOException;import retrofit.Call;import retrofit.Callback;import retrofit.Response;import retrofit.Retrofit;/*** Created by Administrator on 2016/7/25.*/public class TestNetActivity extends Activity {private TextView tv;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_t);tv= (TextView) findViewById(R.id.tv);}public void get(View v){Retrofit retrofit = new Retrofit.Builder().baseUrl("http://www.baidu.com/").build();Itest getBaidu = retrofit.create(Itest.class);//使用上面声明的接口创建Call<ResponseBody> call = getBaidu.get();//获取一个Call,才可以执行请求//异步请求....call.enqueue(new Callback<ResponseBody>() {//异步@Overridepublic void onResponse(Response<ResponseBody> response, Retrofit retrofit) {try {String body = response.body().string();//获取返回体的字符串System.out.println("当前线程："+Thread.currentThread().getName());//是Main线程tv.setText(body);} catch (IOException e) {e.printStackTrace();}}@Overridepublic void onFailure(Throwable t) {}});}}

package com.example.gsc.xinkongjian;import com.squareup.okhttp.ResponseBody;import retrofit.Call;import retrofit.http.GET;/*** Created by Administrator on 2016/7/25.*/public interface Itest {@GET("http://www.baidu.com/")Call<ResponseBody> get();}
