仿京东商品详情页（配合购物车使用）

：使用mvp请求OK来请求网络，在此展示mvp简单使用

一.商品详情页的activity代码

package com.bwie.skn.moni.recyclerDetails;import android.content.Intent;import android.os.Bundle;import android.support.v4.view.ViewPager;import android.support.v7.app.AppCompatActivity;import android.view.View;import android.widget.Button;import android.widget.ListView;import android.widget.TextView;import android.widget.Toast;import com.bwie.skn.moni.R;import com.bwie.skn.moni.adapter.DetailsAdapter;import com.bwie.skn.moni.bean.RecyclerDetailsBean;import com.bwie.skn.moni.shoppingCar.ShoppingCartActivity;import java.util.ArrayList;public class RecyclerDetailsActivity extends AppCompatActivity implements IRecyclerDetailsPresenter,IAddShopCarPresenter{    private int pid = 71;    private RecyclerDetailsPresenter recyclerDetailsPresenter;    private ListView listView;    private RecyclerDetailsBean.DataBean data;    private TextView title;    private TextView price;    private String urlImg;    private String[] split;    private String urlTitle;    private double urlPrice;    private ArrayList<String> lists = new ArrayList<String>();    private ViewPager viewPager;    private DetailsAdapter adapter;    private Button join;    private int pids;    private AddShopCarPresenter addShopCarPresenter;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_details);        viewPager = (ViewPager) findViewById(R.id.viewPager);        join = (Button) findViewById(R.id.join);        title = (TextView) findViewById(R.id.title);        price = (TextView) findViewById(R.id.price);        //Intent intent = getIntent();        //pid = intent.getIntExtra("pid", this.pid);        recyclerDetailsPresenter = new RecyclerDetailsPresenter(this);        recyclerDetailsPresenter.receive(pid + "");        addShopCarPresenter = new AddShopCarPresenter(this);    }    @Override    public void onSuccess(RecyclerDetailsBean rdBean) {        /**         * 从集合获取数据,并赋值         */        data = rdBean.getData();        pids = data.getPid();        urlImg = data.getImages();        split = urlImg.split("\\|");        urlTitle = data.getTitle();        urlPrice = data.getPrice();        title.setText(urlTitle);        price.setText(urlPrice + "");        /**         * 将图片做成无限轮播         * 配置适配器         */        adapter = new DetailsAdapter(RecyclerDetailsActivity.this, split);        viewPager.setAdapter(adapter);        /**         * 点击加入购物车的按钮         */        join.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                /*Toast.makeText(RecyclerDetailsActivity.this, ImageLoaderApp.sql.getInt("id", 0)+"", Toast.LENGTH_SHORT).show();*/                //传入加入购物车的字段                addShopCarPresenter.receive("android", 3381+"", pids + "");            }        });    }    @Override    public void onSuccess(String msg) {        Toast.makeText(RecyclerDetailsActivity.this, msg, Toast.LENGTH_SHORT).show();    }    @Override    public void onFailed() {    }    /**     * 跳转购物车     * @param view     */    public void shopcar(View view){        Intent intent = new Intent(RecyclerDetailsActivity.this, ShoppingCartActivity.class);        startActivity(intent);    }}

二.主页面的布局

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical">    <android.support.v4.view.ViewPager        android:id="@+id/viewPager"        android:layout_width="match_parent"        android:layout_height="250dp"></android.support.v4.view.ViewPager>    <TextView        android:id="@+id/title"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/viewPager"        android:text="标题"        android:textSize="22sp" />    <TextView        android:id="@+id/price"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:layout_below="@id/title"        android:text="价格"        android:textColor="#F00"        android:textSize="22sp" />    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="horizontal"        android:layout_alignParentBottom="true"        >        <Button            android:id="@+id/shopcar"            android:layout_width="0dp"            android:layout_weight="1"            android:layout_height="50dp"            android:text="购物车"            android:onClick="shopcar"            />        <Button            android:id="@+id/join"            android:layout_width="0dp"            android:layout_weight="1"            android:layout_height="50dp"            android:text="加入购物车" />    </LinearLayout></RelativeLayout>

三详情页Viewpager适配器

package com.bwie.skn.moni.adapter;import android.content.Context;import android.support.v4.view.PagerAdapter;import android.view.View;import android.view.ViewGroup;import android.widget.ImageView;import com.bumptech.glide.Glide;import com.bwie.skn.moni.R;/** * author:Created by ZhangPengFei on 2017/12/18. * 详情页的图片的无限轮播 */public class DetailsAdapter extends PagerAdapter {    private Context context;    private String[] split;    public DetailsAdapter(Context context, String[] split) {        this.context = context;        this.split = split;    }    @Override    public int getCount() {        return Integer.MAX_VALUE;    }    @Override    public Object instantiateItem(ViewGroup container, int position) {        View view = View.inflate(context, R.layout.layout_detailviewpager, null);        ImageView img = view.findViewById(R.id.img);        Glide.with(context).load(split[position%split.length]).into(img);        container.addView(view);        return view;    }    @Override    public void destroyItem(ViewGroup container, int position, Object object) {        container.removeView((View) object);    }    @Override    public boolean isViewFromObject(View view, Object object) {        return view==object;    }}

四.商品详情页的Bean页面

package com.bwie.skn.moni.bean;/** * author:Created by ZhangPengFei on 2017/12/17. */public class RecyclerDetailsBean {    /**     * msg :     * seller : {"description":"我是商家17","icon":"http://120.27.23.105/images/icon.png","name":"商家17","productNums":999,"score":5,"sellerid":17}     * code : 0     * data : {"bargainPrice":111.99,"createtime":"2017-10-14T21:39:05","detailUrl":"https://item.m.jd.com/product/4719303.html?utm_source=androidapp&utm_medium=appshare&utm_campaign=t_335139774&utm_term=QQfriends","images":"https://m.360buyimg.com/n0/jfs/t9004/210/1160833155/647627/ad6be059/59b4f4e1N9a2b1532.jpg!q70.jpg|https://m.360buyimg.com/n0/jfs/t7504/338/63721388/491286/f5957f53/598e95f1N7f2adb87.jpg!q70.jpg|https://m.360buyimg.com/n0/jfs/t7441/10/64242474/419246/adb30a7d/598e95fbNd989ba0a.jpg!q70.jpg","itemtype":1,"pid":1,"price":118,"pscid":1,"salenum":0,"sellerid":17,"subhead":"每个中秋都不能简单，无论身在何处，你总需要一块饼让生活更圆满，京东月饼让爱更圆满京东自营，闪电配送，更多惊喜，快用手指戳一下","title":"北京稻香村 稻香村中秋节月饼 老北京月饼礼盒655g"}     */    private String msg;
