推荐答案

如果通过ZXing，符合你的意思是你所使用的库（不斑马线客户端应用程序）来扫描QR codeS，那么你将不得不实现历史有关你自己的功能。基本上每次都成功扫描时间的东西保存在数据库的基础项目。

If by Zxing, you mean you are using the library (not the zxing client app) to scan QR codes then you will have to implement the history related functionality on your own. Basically save items in the database base each time you have successfully scanned something.

看看历史记录功能的样品zxing Android客户端在执行。 <一href=\"https://$c$c.google.com/p/zxing/source/browse/trunk/android/src/com/google/zxing/client/android/history/HistoryManager.java\" rel=\"nofollow\">https://$c$c.google.com/p/zxing/source/browse/trunk/android/src/com/google/zxing/client/android/history/HistoryManager.java

Take a look at the implementation of history feature in the sample zxing android client. https://code.google.com/p/zxing/source/browse/trunk/android/src/com/google/zxing/client/android/history/HistoryManager.java
