OKHTTP封装及调用

package com.example.ok02;

import android.os.Handler;

import java.io.IOException;
import java.util.concurrent.TimeUnit;

import okhttp3.Call;
import okhttp3.Callback;
import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;
public class OkUtils {

    //定义变量
    private static Handler mhandler;
    private final OkHttpClient mclient;
    private static OkUtils mokUtils;

    //使用构造方法，初始化
    private OkUtils(){
        mclient=new OkHttpClient.Builder()
                .connectTimeout(10, TimeUnit.SECONDS)
                .writeTimeout(10,TimeUnit.SECONDS)
                .readTimeout(10,TimeUnit.SECONDS)
                .build();

        mhandler=new Handler();
    }
    //使用单利模式暴露一个方法
    public static OkUtils getInstance(){
        if(mokUtils==null){
            mokUtils=new OkUtils();
        }
        return mokUtils;
    }

    //////////////////////定义接口/////////////////////////
    interface Fucn1{
        Void onresponce(String result);
    }

    //处理请求网络成功的方法
    private static void onSuccessStringData(final String datas,final Fucn1 callBack){
        mhandler.post(new Runnable() {
            @Override
            public void run() {
                if(callBack!=null){
                    callBack.onresponce(datas);
                }
            }
        });
    }
//暴露外界调用的方法
    public void asyncJsonStringByURL(final String url, final Fucn1 callBack){

       final Request request=new Request.Builder().url(url).build();

        mclient.newCall(request).enqueue(new Callback() {
            @Override
            public void onFailure(Call call, IOException e) {

            }

            @Override
            public void onResponse(Call call, Response response) throws IOException {
                onSuccessStringData(response.body().string(),callBack);
            }
        });

    }

}

Mactivity中调用

//使用封装的okhttp
private OkUtils okUtils=OkUtils.getInstance();

 //调用接口的方法
okUtils.asyncJsonStringByURL(path, new OkUtils.Fucn1() {
    @Override
    public Void onresponce(String result) {
        //解析数据
        Gson gson=new Gson();
        ResultDatas resultDatas = gson.fromJson(result, ResultDatas.class);
        List<ResultDatas.DataBean> data = resultDatas.getData();
        //创建适配器
        MyAdaper adaper=new MyAdaper(MainActivity.this,data);
        recyclerView.setAdapter(adaper);
        //开启布局管理器
        recyclerView.setLayoutManager(new LinearLayoutManager(MainActivity.this,LinearLayoutManager.VERTICAL,false));
        return null;
    }
});
