今天用分享动画实现微信点击全屏效果

本文源码下载地址

这里写图片描述 peizhi

配置 build.gradle：

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

在主页添加RecylerView

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

配置Adapter

这里写图片描述

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

这里写图片描述

主要是添加分享元素android:transitionName=”share”，在列表页和详情页的xml的ImageView布局文件中。

最终效果

这里写图片描述

本效果只支持API21+，大家要想实现这个效果的可以参考一下。
