我必须将网站的文本数据保存到存储卡中。然后，我想使用正则表达式来获取电话号码。
我使用这段代码来获取网站:
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.save);
TextView saveText = (TextView) findViewById(R.id.save_text);
String t = "";
String urltext = "http://vnexpress.net/";
try {
t = get_source_html(urltext);
} catch (Exception e) {
e.toString();
}
saveText.setText(t);
}
public static String get_source_html(String urltext) throws IOException {
URL url = new URL(urltext);
BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
String inputLine;
String s = "";
while ((inputLine = in.readLine()) != null) {
s = s + inputLine;
}
s = s + "";
in.close();
return s;
}
但是我无法从文本数据中获取电话号码。你能帮帮我吗？
最佳答案
你可以试试这个网站的正则表达式

Title Test

International & Domestic Phone Numbers with Ext
Expression ^([\+][0-9]{1,3}([ \.\-])?)?([\(]{1}[0-9]{3}[\)])?([0-9A-Z \.\-]{1,32})((x|ext|extension)?[0-9]{1,4}?)$
Description Somewhat conservative expression for evaluating phone numbers. Based off ideas found at http://stackoverflow.com/questions/123559/a-comprehensive-regex-for-phone-number-validation this allows country codes, with or without the + symbol, area codes surrounded by parenthesis (or not) and numbers delimited by spaces, periods or dashes. You'll want to independently test for string length based on your needs.
