问题描述
我有一个简单的Android应用程序，拉在ListView的手机和显示器上的所有音乐文件。在code正常工作，但任何时候我换一首歌的SD卡，可以添加或删除，不显示的变化。它看起来好像SD卡进行高速缓存的东西。如果我重新安装SD卡，显示的变化。我可以关闭仿真器，并重新启动它，仍然没有什么变化，直到我重新安装。我怎样才能得到模拟器上读取SD卡更改，而不必重新安装每次有变化？我缺少一个设置或东西？
I have a simple Android app that pulls all music files on the phone and displays in a listView. The code works fine, but any time I change a song on the sdcard, either adding or deleting, the changes are not displayed. It looks as if the sdcard is cached or something. If I remount the sdcard, the changes are displayed. I can shut down the emulator and start it back up and still nothing changes until I remount. How can I get the emulator to read changes on the sdcard without having to remount every time there is a change? Am I missing a setting or something?
