Android(安卓)中SwipeRefreshLayout刷新动画不显示的问题

开始使用SwipeRefreshLayout中容纳一个ListView的时候进行刷新不会有任何问题，但是当我把SwipeRefreshLayout中的子元素换成TextView后问题出现了，刷新的时候动画显示居然不完整！刚跳出来就结束了。

查询文档，文档中有这么一句

If an activity wishes to show just the progress animation, it should call setRefreshing(true)

不幸的是问题依旧。

后来参看了匆忙拥挤repeat 的代码将ScrollView作为SwipeRefreshLayout的子元素，将TextView添加到ScrollView中，问题圆满解决。

附上测试源码

布局文件 activity_main.xml

MainActivity.java
