PhotoView点击放大图片效果

使用的PhotoView是这个版本的，比较小巧，很好用，比github上另一个版本的瘦身很多：

基本测试代码如下：

import java.util.ArrayList;

import android.content.Context;
import android.os.Bundle;
import android.support.v7.widget.DefaultItemAnimator;
import android.support.v7.widget.GridLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.view.View;

import com.widget.common.recycler.BaseRecyclerAdapter;
import com.widget.common.recycler.SpacesItemDecoration;
import com.widget.common.recycler.ViewHolder;
import com.widget.photoView.Info;
import com.widget.photoView.PhotoView;

仿微博、微信、qq 点击缩略图后预览高清图的组件

TransferImage 是一款模仿微博、微信、qq的高清图查看控件, 实现了在列表控件(ListView, RecycleView, GridView 等...)中 点击缩略图后播放过渡动画, 加载高清图, 加载高清图时同时显示加载进度条, 加载完成后显示高清图的一个组件。同时关闭 TransferImage 也会有对应的过渡动画.

此库若有不完善的地方, 请提 Issues, 我会尽快修复改善

支持或包含的功能：

打开和关闭 TransferImage 的过渡动画, 支持自定义
图片加载内置了一个使用 Glide 框架的图片加载器, 支持自定义
图片支持手势操作, 可缩放、双击、移动
图片加载时的进度条, 支持自定义
图片索引指示器, 支持自定义
