如何在Android中获取iData（移动计算机iData95E）iScan条形码图像？

iData iScan是由无锡iData科技有限公司开发的一项技术。 它通过iData内置扫描仪应用程序iScan用于条形码扫描仪

任何人都可以提供任何其他文件或参考。 因此，我可以在扫描后获得条形码数据

感谢您的积极回复。

我有用于扫描条形码的iData设备。获取条形码数据非常简单，只需在屏幕上放置一个edittext，将当前焦点设置为edittext，然后使用iData设备扫描条形码，现在您可以看到，在成功扫描条形码后，iData设备默认情况下将条形码编号添加到edittext。

旧问题但新答案。这样，它不需要编辑文本

• 步骤1（可选，但推荐）

如果需要，使用谷歌翻译。 在那里，您将获得最新的iScan应用程序。此步骤不是必需的，但建议执行。
点击下载链接：

链接：密码：pa4s

您将得到404错误，好的，将url从

pan.baidu.com

重写到

yun.baidu.com

。现在url看起来像这样：

http://yun.baidu.com/s/1bpl50uj

。转到该链接，输入密码并下载应用程序

• 步骤2

。同样，您必须将地址从

pan

更改为

yun

。输入密码并下载文件

之后，您可以探索该应用程序的来源。您需要

libbarcode.so
from
libs/armeabi/
和
BarcodeScan.jar
from
libs/

libbarcode.so
必须放入
jniLibs\armeabi
文件夹
BarcodeScan.jar
必须添加为依赖项

MainActivity.w（）
只是
Log.d（）的包装。希望它能帮助某些人：）
如何在没有焦点文本的情况下获取条形码编号？例如，在后台接收服务@希拉格Raval@DomezchociData设备将仅在编辑文本字段中返回条形码编号。我不确定在后台服务中是否收到条形码号码
