推荐答案

我们不能 - 大多数条形码扫描仪都是用来模拟键盘的，所以当扫描代码时，它会像在键盘上输入一样到达活动应用程序。

大多数扫描仪可以重新配置为提供前导和尾随数据，分别表示条形码开始和条形码结束，这应该可以让你做你想做的事情。但是，您如何配置它（以及您可以获得的引导和跟踪序列）因制造商而异（甚至从模型到模型）。联系您的特定设备的制造商（或查看手册），他们应该能够帮助您。

We can't - most barcode scanners are shipped to emulate a keyboard, so when the code is scanned, it arrives at the active application exactly as if it had been typed on a keyboard.
Most scanners can be reconfigured to provide leading and trailing data to indicate "barcode start" and "barcode end" respectively, and that should enable you to do what you want. But how you configure it (and what you can get as the lead and trail sequences) varies from manufacturer to manufacturer (and even model to model). Contact the manufacturer of your specific device (or look in the manual) and they should be able to help you.
