我正在使用谷歌的 android 移动视觉 OCR 文本构建一个 android 应用程序,用于将名片作为手机中的联系人输入。
到目前为止,我已经能够识别任何拉丁生成文本,并且能够在代码块上应用正则表达式
我所做的是,我为五个变量名称、电子邮件、公司名称、网站、adrs、phnno 创建了一个联系人 bean 类在对生成的实时数据应用正则表达式后,我正在过滤结果并将它们保存在 bean 类型的对象中类并将该对象传递给活动并提取存储在该对象中的数据并将其显示在我的文本视图中。

我已按照上述教程进行操作,我有以下问题
a-) 如何使用文本行而不是文本块?
b-) 我在 Graphic 类中使用 Timer Task 完成后如何杀死它还是应该使用其他方法?
c-) 有没有任何应用程序,我还没有找到一个使用视觉 OCR 进行名片输入的应用程序,但他们说它可以吗?
d-) 我的正则表达式 exp 在单独的 Java IDE 中经过正确测试有什么建议吗?
e-) 我正在使用额外的意图来获取存储在联系人 bean 对象中的数据并将其显示在活动中,它就像一个雪球永远不会停止,尽管我已经在我的IF STATEMENTS 中放置了标志。
f-) 在某个时候,我们可以阻止 OCR 库在所有标志都为真后检测任何进一步的文本。或者只是任何方式?
g-)无论条件为真与否,它都会不断覆盖我的变量?
所有的帮助都会受到高度重视。谢谢分配。
