首先感谢这个哥们，把我从helloworld教会了。

retrofit 我花了两天的时间才学会，开始的时候，找资料，他们都讲得太深了，我从来没有成功过。知道上面的那个哥们的博客。 真的，我就喜欢一开始从最开始的做起。
retrofit
简单的：
1.首先
compile ‘com.squareup.retrofit:retrofit:2.0.0-beta2’
compile ‘com.squareup.okhttp:okhttp:2.5.0’
compile ‘com.squareup.okio:okio:1.6.0’
compile ‘com.google.code.gson:gson:2.4’
compile ‘com.squareup.retrofit:converter-gson:2.0.0-beta2’
2.声明接口
public interface GetBaidu{
@GET(“http://www.baidu.com/“)
Call get();
//Call get();//必须是这种形式,这是2.0之后的新形式
//我这里需要返回网页内容,不需要转换成Json数据,所以用了ResponseBody;
//你也可以使用Call get();这样的话,需要添加Gson转换器…后续介绍
}
3.调用接口
//经过测试: baseUrl必须设置,如果 声明接口时@GET使用了完整的url路径,那么baseUrl就会被忽略,否则就是拼接url
Retrofit retrofit = new Retrofit.Builder().baseUrl(“http://www.baidu.com/“).build();//在这里可以添加 Gson转换器等;
GetBaidu getBaidu = retrofit.create(GetBaidu.class);//使用上面声明的接口创建
Call call = getBaidu.get();//获取一个Call,才可以执行请求
//同步请求….
try {
Response bodyResponse = call.execute();
String body = bodyResponse.body().string();//获取返回体的字符串
Log.e(TAG, “”);
} catch (IOException e) {
e.printStackTrace();
}
//异步请求….
call.enqueue(new Callback() {//异步
@Override
public void onResponse(Response response, Retrofit retrofit) {
try {
String body = response.body().string();//获取返回体的字符串
} catch (IOException e) {
e.printStackTrace();
}
Log.e(TAG, “”);
}
@Override
public void onFailure(Throwable t) {
Log.e(TAG, "");
}
});
2.复杂点的 ，直接解析json的
1.首先
compile ‘com.squareup.retrofit:retrofit:2.0.0-beta2’
compile ‘com.squareup.okhttp:okhttp:2.5.0’
compile ‘com.squareup.okio:okio:1.6.0’
compile ‘com.google.code.gson:gson:2.4’
compile ‘com.squareup.retrofit:converter-gson:2.0.0-beta2’
2.声明接口
public interface GetBaidu{
@GET("LifePayment/user/login.json?_mt=5849414f4d492c47554343492c342e342e34&_pla=6365625f616e64725f312e342e365f756e695f636562&_pro=30&_ss=3732307831323830&_uid=383637383232303236393838323934&_ver=1.4.6&mobile=3135383130323938363730&pwd=3936653739323138393635656237326339326135343964643561333330313132&version=1.4.6&macValue=55F5BA03AC37288BF122D1745832EE2D")
Call<ResponseCode> get();
//Call<T> get();//必须是这种形式,这是2.0之后的新形式
//我这里需要返回网页内容,不需要转换成Json数据,所以用了ResponseBody;
//你也可以使用Call<GsonBean> get();这样的话,需要添加Gson转换器...后续介绍
}ResponseCode只是一个javabean

- 使用
package cn.xinyu.com.myapplication;

import android.view.GestureDetector;
import android.widget.TextView;
import android.widget.Toast;

import retrofit.Response;
import retrofit.Retrofit;
public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ButterKnife.bind(this);
//经过测试: baseUrl必须设置,如果 声明接口时@GET使用了完整的url路径,那么baseUrl就会被忽略,否则就是拼接url
Gson gson = new GsonBuilder()
// 2013-09-14 16:45:29
.setDateFormat("yyyy-MM-dd HH:mm:ss")
// .setDateFormat("yyyy-MM-dd'T'HH:mm:ssZ")
.create();
Retrofit retrofit = new Retrofit.Builder().baseUrl("http://testopen.cebbank.com/")
.addConverterFactory(GsonConverterFactory.create(gson))
.build();//在这里可以添加 Gson转换器等;
GetBaidu getBaidu = retrofit.create(GetBaidu.class);//使用上面声明的接口创建
Call<ResponseCode> call = getBaidu.get();//获取一个Call,才可以执行请求
//
//异步请求....
call.enqueue(new Callback<ResponseCode>() {//异步
// @Override
// public void onResponse(Response<ResponseBody> response, Retrofit retrofit) {
// try {
// String body = response.body().string();//获取返回体的字符串
// Toast.makeText(MainActivity.this,body,Toast.LENGTH_LONG).show();
// textView.setText(body);
//
// } catch (IOException e) {
// e.printStackTrace();
// }
// }
@Override
public void onResponse(Response<ResponseCode> response, Retrofit retrofit) {
ResponseCode responseCode=response.body();
textView.setText(responseCode.getUserModel().getQqAppKey());
}
@Override
public void onFailure(Throwable t) {
Toast.makeText(MainActivity.this,"failed",Toast.LENGTH_LONG).show();
textView.setText(t.toString());
}
});
}
}
如果你的json里面有日期，那么要用个日期转换，不然就会
com.google.gson.JsonSyntaxException: 2013-09-14 16:45:29
