Okhttp解析Gson数据并且展示到recyclerView

1、这篇文章主要应用的是Okhttp请求网络数据解析Gson，判断网络，没有网络跳转到设置界面，然后通过XRecyclerView展示到页面中。并且可以实现全局捕获异常，加载图片实现属性动画渐变的效果。

2、导入依赖

compile 'com.squareup.okhttp:okhttp:2.4.0'
compile 'io.github.openfeign:feign-gson:9.5.1'
compile 'com.github.bumptech.glide:glide:3.8.0'
compile 'com.jcodecraeer:xrecyclerview:1.3.2'

这四个依赖分别是okhttp的依赖、Gson的依赖、图片加载Glide的依赖、XrecyclerView的依赖

3、配置权限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

这两个权限分别是编写的权限跟联网的权限

4、MainActivity中的布局，只需要布一个XrecyclerView的布局就可以了

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >

    <com.jcodecraeer.xrecyclerview.XRecyclerView
        android:id="@+id/recycler"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
         ></com.jcodecraeer.xrecyclerview.XRecyclerView>

</RelativeLayout>

5、MainActicity中的数据

import android.content.Context;
import android.content.Intent;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;
import android.os.Bundle;
import android.os.Handler;

import android.support.v7.widget.LinearLayoutManager;
import android.util.Log;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.bumptech.glide.Glide;
import com.google.gson.Gson;
import com.jcodecraeer.xrecyclerview.XRecyclerView;

    private int page = 1;//设置首先展示的页面是第一页
    private Handler handler = new Handler() {

        @Override
        public void handleMessage(Message msg) {

            Gson gson = new Gson();
            Bean bean = gson.fromJson(u, Bean.class);
           list = bean.getData();
            //设置布局管理器
            recycler.setLayoutManager(new LinearLayoutManager(MainActivity.this));
            //设置适配器
            recycler.setAdapter(new MyAdapter());
            //分页加的
            recycler.setLoadingListener(new XRecyclerView.LoadingListener() {
                @Override

                public void onRefresh() {
                    page = 1;
                    list.clear();
                    jiexi();
                    recycler.refreshComplete();
                }

                @Override
                //上拉加载
                public void onLoadMore() {
                    page++;
                    jiexi();
                    Toast.makeText(MainActivity.this, "加载更多", Toast.LENGTH_LONG).show();
                    recycler.loadMoreComplete();
                }
            });

        }
    };


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //判断网络
