How do I delete SharedPreferences data for my application?
我正在创建一个使用大量Web服务来同步数据的应用程序.出于测试目的,我需要在重新启动应用程序时清除一些SharedPreferences值.
I'm creating an application that uses a lot of web services to sync data. For testing purposes, I need to wipe out some SharedPreferences values when I restart the app.
推荐答案
To remove specific values: SharedPreferences.Editor.remove() followed by a commit()
要删除所有SharedPreferences.Editor.clear()
,然后再删除commit()
To remove them all SharedPreferences.Editor.clear()
followed by a commit()
如果您不关心返回值,而在应用程序的主线程中使用此返回值,请考虑改用apply()
.
If you don't care about the return value and you're using this from your application's main thread, consider using apply()
instead.
