我使用sqlite的加载器,处理程序线程(带队列的looper)和listview,
我需要在列表视图中下载文件时向用户显示进度条。
我正在考虑下面的内容,但它看起来并不正确,因为我将大量更改数据源,
1 - User clicks "Download file icon"
2 - Video starts downloading
3 - Update the sql table with the progress
4 - Notify the loader to reload the data
5 - I have the code that keeps the list view at its current position after changing the data source
我想不出另一种解决方案,还有其他选择吗?
