这只是一个练习案例
首先，需要导入的依赖有：
compile 'com.jakewharton:butterknife:8.8.1'
compile 'com.jakewharton:butterknife-compiler:8.8.1'
compile 'com.squareup.retrofit2:retrofit:2.2.0'
compile 'com.squareup.okhttp3:logging-interceptor:3.3.0'
compile 'com.squareup.retrofit2:converter-gson:2.3.0'
compile 'com.android.support:recyclerview-v7:24.0.0'
compile 'com.squareup.picasso:picasso:2.5.2'
其次预先设置好网络权限：
<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
下面就可以开始项目的创建了：
首先是布局文件
activity_main.xml
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_main" android:layout_width="match_parent" android:layout_height="match_parent" tools:context="com.example.day01_rikao.MainActivity"> <android.support.v7.widget.RecyclerView android:id="@+id/recyclerView" android:layout_width="match_parent" android:layout_height="match_parent"></android.support.v7.widget.RecyclerView></RelativeLayout>
layout_recycler.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="match_parent" android:layout_height="wrap_content"> <ImageView android:layout_weight="1" android:id="@+id/iv_id" android:layout_width="0dp" android:layout_height="wrap_content"/> <TextView android:layout_weight="1" android:id="@+id/tv_id" android:layout_width="0dp" android:layout_height="wrap_content"/></LinearLayout>
接着是Java文件：
Film.java
package com.example.day01_rikao;import java.util.List;/** * Created by Me on 2017/12/25. */public class Film { /** * status : 0 * msg : OK * data :
