如何正确导入 libphonelib 到 java 项目？

Question

我正在尝试使用 libphonenumber 库中的 PhoneNumberMatcher。将 jar 文件添加到我的项目并设置 BuildPath 后，我能够将 classes 导入到我的项目中：

import com.google.i18n.phonenumbers.*;

在库中，有一个名为 PhoneNumberMatcher.class 的 class。我一直在尝试找到它，但是这个 class 名称不包含在我按 Ctrl + Space.[=15= 时通常得到的建议中]

如果我坚持写名字 class，eclipse 会在名字和消息 "The type PhoneNumberMatcher is not visible". 下划线最近我意识到 class 在项目资源管理器中有一个小蓝旗图标。

它不是唯一一个有这样一个蓝旗的，然后我尝试了其他 classes 并且我意识到所有带有这个蓝旗的 classes 都不可访问。这就是为什么我认为这些 classes 可能是私有的，或者供 lib 内部使用。

我正在尝试创建一个工具来从文本中提取 phone 个数字，我读到这个库正是为此而准备的。

请问如何在我的 java 项目中使用 PhonNumberMatcher class？

Answer 1

 CharSequence text = "Call me at +1 425 882-8080 for details.";
 String country = "US";
 PhoneNumberUtil util = PhoneNumberUtil.getInstance();

 // Find the first phone number match:
 PhoneNumberMatch m = util.findNumbers(text, country).iterator().next();

 // rawString() contains the phone number as it appears in the text.
 "+1 425 882-8080".equals(m.rawString());

 // start() and end() define the range of the matched subsequence.
 CharSequence subsequence = text.subSequence(m.start(), m.end());
 "+1 425 882-8080".contentEquals(subsequence);

 // number() returns the the same result as PhoneNumberUtil.parse()
 // invoked on rawString().
 util.parse(m.rawString(), country).equals(m.number());

Answer 2

谢谢你的回答，Chana。我确实能够使用该库，但后来我意识到该库对我来说使用起来太复杂了，所以我编写了自己的代码来提取德国 phone 号码、IBAN、邮政编码和金额，然后然后分类：

import java.util.ArrayList;
import java.util.List;
import java.util.regex.Matcher;
import java.util.regex.Pattern;

public static final String REGEXIbanNumbers = "([A-Z][ -]?){2}([0-9]([ -]?)*){12,30}";
