okttp的get异步和同步 post的异步简单使用情况

package com.example.day12okhttp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

import java.io.IOException;

import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.FormBody;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

//第一步在build里面添加依赖添加到modul里面
//第二部创建okhttpclient 客户端对象

public class MainActivity extends AppCompatActivity {
String url ="http://www.meirixue.com/api.php?c=index&a=index";
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
//okhttp   get同步请求网络
public  void get(View v){

new Thread(){

@Override
public void run() {
super.run();
//创建客户端对像
OkHttpClient client = new OkHttpClient();

//request 里面我们可以做一些请求的地址，请求方式，
Request request = new Request.Builder()
.url(url)

.build();

//去请求网络网络  okhttp有同步请求和异步请求 execute   enqueue异步请求
try {
//从服务器端返回的response
Response response = client.newCall(request).execute();
//从服务器返回的json字符串
String json = response.body().string();

Log.e("MainActivity",json);

} catch (IOException e) {
e.printStackTrace();
}

}
}.start();
}

//get异步请求
public void getyi(View v){

} catch (Exception e) {
