先上一个Telegram的媒体样式， 后面是自定义是实现效果

在来看一下实现的效果

大概说一下实现的方式，目前用的是DialogFragment全屏实现，自定义滚动视图，利用pictureselector图片库 获取数据源，列表第一个是打开的相机，根据官方提供的相机库 实现绑定生命周期显示相机。
先看滚动视图，首先你得知道你的滚动视图分为几个view，占几部分，我这里写的固定view，如果满足不了你的需求请自行修改
DialogFragment中滚动View

这里面主要就是测量view的大小，计算出滚动的距离，还有显示的位置等；(滚动距离还有显示位置根据自己需求自行修改)
下面才是媒体显示的页面，主要介绍一下逻辑部分(布局就不贴了，尾部给链接，自行查看)
在滚动的时候 上面的导航标题栏显示隐藏；并且可以点击切换相册媒体文件，点击图片带有选中的序号，按照顺序显示；下方带有说明的输入框；在列表的第一个是打开的相机，这里相机是需要绑定生命周期的，直接传入DialogFragment，点击之后进入自定义拍照相机页面， 拍照介绍返回图片添加进入列表显示

选中的逻辑处理，Tegegram选中之后是有一个缩放的效果的，我这目前需求没有，就只加上一层遮罩，然后处理选中的数字排序，但由于用的是pictureselector库，那里面也有已经处理完的数字排序，就没有重复造轮子了，网上也是一搜一堆的，我就直接用库自带的了；然后设置一下字体大小，如果超过两位数的话那么重新设置一下，不然显示不下了。

关闭DialogFragment，因为图片是可以添加说明的，所以需要先判断键盘，如果显示就先关闭键盘，再则判断是否有选中的图片，如果有的话 需要再次弹出一个确认提示框(这个图方便就快速写了一个，不标准，按照自己需求写就可以)，如果确认关闭那么就清除选中的数据缓冲，添加一个DialogFragment的关闭动画。在销毁的时候把初始化长按滚动选中释放掉。
以上基本就是选中媒体图片的弹框了，我的需求查看图片跟Telegram的有点不太一样，还有查看预览的图文混排，目前注释掉了，如果后续有时间的话我会补上，会有一个图文混排和图片预览的介绍。
