配置 build.gradle：

  compile 'com.android.support:recyclerview-v7:23.3.0'compile 'com.squareup.picasso:picasso:2.3.2'

在主页加入RecylerView

 @Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);recyclerView = (RecyclerView) findViewById(R.id.recylerview);recyclerView.setHasFixedSize(true);recyclerView.setLayoutManager(new GridLayoutManager(this, 3));recyclerView.setAdapter(adapter = new PicassoAdapter(this));adapter.replaceAll(getData());}private ArrayList<String> getData() {ArrayList<String> list = new ArrayList<>();for (int i = 0; i < ImageUtil.imageUrls.length; i++) {list.add(ImageUtil.imageUrls[i]);}return list;}

初始化数据：

package com.example.wangchang.testpicasso;/*** Created by WangChang on 2016/4/3.*/
public class ImageUtil {public final static String[] imageUrls = new String[]{"https://img-my.csdn.net/uploads/201508/05/1438760758_3497.jpg","https://img-my.csdn.net/uploads/201508/05/1438760758_6667.jpg","https://img-my.csdn.net/uploads/201508/05/1438760757_3588.jpg","https://img-my.csdn.net/uploads/201508/05/1438760756_3304.jpg","https://img-my.csdn.net/uploads/201508/05/1438760755_6715.jpeg","https://img-my.csdn.net/uploads/201508/05/1438760726_5120.jpg","https://img-my.csdn.net/uploads/201508/05/1438760726_8364.jpg","https://img-my.csdn.net/uploads/201508/05/1438760725_4031.jpg","https://img-my.csdn.net/uploads/201508/05/1438760724_9463.jpg","https://img-my.csdn.net/uploads/201508/05/1438760724_2371.jpg","https://img-my.csdn.net/uploads/201508/05/1438760707_4653.jpg","https://img-my.csdn.net/uploads/201508/05/1438760706_6864.jpg","https://img-my.csdn.net/uploads/201508/05/1438760706_9279.jpg","https://img-my.csdn.net/uploads/201508/05/1438760704_2341.jpg","https://img-my.csdn.net/uploads/201508/05/1438760704_5707.jpg","https://img-my.csdn.net/uploads/201508/05/1438760685_5091.jpg","https://img-my.csdn.net/uploads/201508/05/1438760685_4444.jpg","https://img-my.csdn.net/uploads/201508/05/1438760684_8827.jpg","https://img-my.csdn.net/uploads/201508/05/1438760683_3691.jpg","https://img-my.csdn.net/uploads/201508/05/1438760683_7315.jpg","https://img-my.csdn.net/uploads/201508/05/1438760663_7318.jpg","https://img-my.csdn.net/uploads/201508/05/1438760662_3454.jpg","https://img-my.csdn.net/uploads/201508/05/1438760662_5113.jpg","https://img-my.csdn.net/uploads/201508/05/1438760661_3305.jpg","https://img-my.csdn.net/uploads/201508/05/1438760661_7416.jpg","https://img-my.csdn.net/uploads/201508/05/1438760589_2946.jpg","https://img-my.csdn.net/uploads/201508/05/1438760589_1100.jpg","https://img-my.csdn.net/uploads/201508/05/1438760588_8297.jpg","https://img-my.csdn.net/uploads/201508/05/1438760587_2575.jpg","https://img-my.csdn.net/uploads/201508/05/1438760587_8906.jpg","https://img-my.csdn.net/uploads/201508/05/1438760550_2875.jpg","https://img-my.csdn.net/uploads/201508/05/1438760550_9517.jpg","https://img-my.csdn.net/uploads/201508/05/1438760549_7093.jpg","https://img-my.csdn.net/uploads/201508/05/1438760549_1352.jpg","https://img-my.csdn.net/uploads/201508/05/1438760548_2780.jpg","https://img-my.csdn.net/uploads/201508/05/1438760531_1776.jpg","https://img-my.csdn.net/uploads/201508/05/1438760531_1380.jpg","https://img-my.csdn.net/uploads/201508/05/1438760530_4944.jpg","https://img-my.csdn.net/uploads/201508/05/1438760530_5750.jpg","https://img-my.csdn.net/uploads/201508/05/1438760529_3289.jpg","https://img-my.csdn.net/uploads/201508/05/1438760500_7871.jpg","https://img-my.csdn.net/uploads/201508/05/1438760500_6063.jpg","https://img-my.csdn.net/uploads/201508/05/1438760499_6304.jpeg","https://img-my.csdn.net/uploads/201508/05/1438760499_5081.jpg","https://img-my.csdn.net/uploads/201508/05/1438760498_7007.jpg","https://img-my.csdn.net/uploads/201508/05/1438760478_3128.jpg","https://img-my.csdn.net/uploads/201508/05/1438760478_6766.jpg","https://img-my.csdn.net/uploads/201508/05/1438760477_1358.jpg","https://img-my.csdn.net/uploads/201508/05/1438760477_3540.jpg","https://img-my.csdn.net/uploads/201508/05/1438760476_1240.jpg","https://img-my.csdn.net/uploads/201508/05/1438760446_7993.jpg","https://img-my.csdn.net/uploads/201508/05/1438760446_3641.jpg","https://img-my.csdn.net/uploads/201508/05/1438760445_3283.jpg","https://img-my.csdn.net/uploads/201508/05/1438760444_8623.jpg","https://img-my.csdn.net/uploads/201508/05/1438760444_6822.jpg","https://img-my.csdn.net/uploads/201508/05/1438760422_2224.jpg","https://img-my.csdn.net/uploads/201508/05/1438760421_2824.jpg","https://img-my.csdn.net/uploads/201508/05/1438760420_2660.jpg","https://img-my.csdn.net/uploads/201508/05/1438760420_7188.jpg","https://img-my.csdn.net/uploads/201508/05/1438760419_4123.jpg",};

}

详情页xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"><ImageView
        android:id="@+id/iv_image"android:layout_width="200dp"android:layout_height="200dp"android:layout_gravity="center_horizontal"android:layout_marginTop="100dp"android:scaleType="fitXY"android:src="@mipmap/ic_launcher"android:transitionName="share" /><TextView
        android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_gravity="center_horizontal"android:layout_marginTop="24dp"android:text="用户姓名"android:textSize="18sp"android:textStyle="bold" /><TextView
        android:layout_width="wrap_content"android:layout_height="wrap_content"android:layout_margin="24dp"android:text="你是我的小呀小苹果,你是我的小呀小苹果,你是我的小呀小苹果,你是我的小呀小苹果你是我的小呀小苹果,你是我的小呀小苹果" />
</LinearLayout>

效果图

主要是加入分享元素android:transitionName=”share”。在列表页和详情页的xml的ImageView布局文件里。

终于效果

本效果仅仅支持API21+。大家要想实现这个效果的能够參考一下。
