我目前正在尝试使用商务名片扫描仪应用。这里的想法是拍一张名片的照片,它会提取文本并将文本分类为不同的EditText。
我已经完成了OCR部分,它从名片图像中提取出所有文本。
我现在缺少的是制作一个正则表达式方法,可以从OCR中提取整个文本,并将名称,电子邮件地址,电话号码分类到EditText各自的字段中。
通过一些谷歌搜索,我已经找到了下面的正则表达式:
private static final String EMAIL_PATTERN =
"[a-zA-Z0-9\\+\\.\\_\\%\\-\\+]{1,256}" +
"\\@" +
"[a-zA-Z0-9][a-zA-Z0-9\\-]{0,64}" +
"(" +
"\\." +
"[a-zA-Z0-9][a-zA-Z0-9\\-]{0,25}" +
")+";
private static final String PHONE_PATTERN =
"^[89]\\d{7}$";
private static final String NAME_PATTERN =
"/^[a-z ,.'-]+$/i";
目前我只是能够使用以下方法提取电子邮件地址:
public String EmailValidator(String email) {
Pattern pattern = Pattern.compile(EMAIL_PATTERN);
Matcher matcher = pattern.matcher(email);
if (matcher.find()) {
return email.substring(matcher.start(), matcher.end());
} else {
// TODO handle condition when input doesn't have an email address
}
return email;
}
我不确定如何编辑 ^ above method ^ 以包含一次使用所有3个正则表达式模式,并将它们显示到不同的EditText字段,如(姓名,电子邮件地址,电话号码)。

使用@Styx回答后,
它的参数有问题,我用它如何将文本“textToUse”传递给方法,如下所示:
我也尝试将文本传递给所有三个参数。但由于该方法为void
,因此无法完成。或者,如果我将方法更改为String
而不是void
,则需要返回值。
答案 0 :(得分:4)
试试这段代码。该函数接收识别文本并使用折线符号将其拆分。然后运行循环并通过运行模式检查来确定内容的类型。每当确定模式时,循环将使用 continue 关键字进入下一次迭代。这段代码还能够处理单个名片上出现1个或多个电子邮件和电话号码的情况。希望能帮助到你。干杯!
public void validator(String recognizeText) {
Pattern emailPattern = Pattern.compile(EMAIL_PATTERN);
Pattern phonePattern = Pattern.compile(PHONE_PATTERN);
Pattern namePattern = Pattern.compile(NAME_PATTERN);
String possibleEmail, possiblePhone, possibleName;
possibleEmail = possiblePhone = possibleName = "";
Matcher matcher;
String[] words = recognizeText.split("\\r?\\n");
for (String word : words) {
//try to determine is the word an email by running a pattern check.
matcher = emailPattern.matcher(word);
if (matcher.find()) {
possibleEmail = possibleEmail + word + " ";
continue;
}
//try to determine is the word a phone number by running a pattern check.
matcher = phonePattern.matcher(word);
if (matcher.find()) {
possiblePhone = possiblePhone + word + " ";
continue;
}
//try to determine is the word a name by running a pattern check.
matcher = namePattern.matcher(word);
if (matcher.find()) {
possibleName = possibleName + word + " ";
continue;
}
}
//after the loop then only set possibleEmail, possiblePhone, and possibleName into
//their respective EditText here.
}
