		4	+demo的主要逻辑是，利用okhttp 和 RxJava 在子线程中下载文件，通关观察者模式监听下载的进度，再回调到主线程中，然后利用EventBus 通知页面刷新，更新进度。

		406	+这里是用到EventBus来通知页面刷新的，当然也可以不用，把订阅者直接写在Activity，但是那样不利于代码的复用，如果多个页面需要进度更新就麻烦了。

		408	+页面中是一个RecyclerView，交互逻辑不是很多，说一点，Adapter条目的更新，用的notifyItemChanged(i) 每次更新某一条的进度，而不是notifyDataSetChanged()全部刷新，因为调用全部刷新，刷新的频率很高会导致条目中控件的点击事件不好用没有响应，被拦截了，而更新某一条也会有一个问题是条目刷新时会闪动，解决方案是把RecyclerView的刷新动画去掉，这样就解决了。
