[b]清单文件中加入权限[/b]

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

配置application的name属性,ImageLoader初始化

<application 

    android:name=".appli.App" 

</application>  

public class App extends Application{ 

    @Override  
    public void onCreate() {  
        super.onCreate(); 

        ImageLoaderConfiguration configuration = new ImageLoaderConfiguration.Builder(this).build(); 

        ImageLoader.getInstance().init(configuration); 

    }  
} 

布局中需要用到的

的布局,在drawable下面新建qujiesuan.xml

<?xml version="1.0" encoding="utf-8"?>  
<shape xmlns:android="http://schemas.android.com/apk/res/android">  
  
    <corners android:radius="200dp"/>  
    <solid android:color="#e53e42"/>  
    <size android:height="60dp" android:width="130dp"/> 

</shape> 

drawable下面还需要加入三张图片

recy_cart_item.xml,需要引入 自定义组合控件,在创建了CustomJiaJian类以后才可以引入

接下来就是MVP了

moder层 的接口

package com.example.samsung.myapplication.moderl;

public interface IHome {
