I want to parse the url from a String in android. The example String is
"This is a new message. The content of the message is in 'http://www.example.com/asd/abc' "
I want to parse the url http://www.example.com/asd/abc from the String without using the subString method.
Use this:
public static String[] extractLinks(String text) {
List<String> links = new ArrayList<String>();
Matcher m = Patterns.WEB_URL.matcher(text);
while (m.find()) {
String url = m.group();
Log.d(TAG, "URL extracted: " + url);
links.add(url);
}
return links.toArray(new String[links.size()]);
}
Updated:
You can use regular expression with Patterns.WEB_URL regular expression to find all urls in your text.
Original:
You can use Uri.parse(String uriString) function.
If you are parsing the links for the purpose of styling them, Linkify is an elegant solution:
descriptionTextView.setText("This text contains a http://www.url.com")
Linkify.addLinks(descriptionTextView, Linkify.WEB_URLS);
You can also change the default colour of the link:
descriptionTextView.setLinkTextColor(ContextCompat.getColor(getContext(),
R.color.colorSecondary));
The result looks like this:
Yes its possible. Try with the following code sample
ArrayList retrieveLinks(String text) {
ArrayList links = new ArrayList();
String regex = "\\(?\\b(http://|www[.])[-A-Za-z0-9+&@#/%?=~_()|!:,.;]*[-A-Za-z0-9+&@#/%=~_()|]";
Pattern p = Pattern.compile(regex);
Matcher m = p.matcher(text);
while(m.find()) {
String urlStr = m.group();
char[] stringArray1 = urlStr.toCharArray();
if (urlStr.startsWith("(") && urlStr.endsWith(")"))
{
char[] stringArray = urlStr.toCharArray();
char[] newArray = new char[stringArray.length-2];
System.arraycopy(stringArray, 1, newArray, 0, stringArray.length-2);
urlStr = new String(newArray);
System.out.println("Finally Url ="+newArray.toString());
}
System.out.println("...Url..."+urlStr);
links.add(urlStr);
}
return links;
}
Thanks Deepak
I use this in Kotlin
fun findAllUrls(text: String): List<String> {
return Regex(Patterns.WEB_URL.pattern()).findAll(text).map {
it.value
}.toList()
}
You can just create a new URL passing the string as the argument to the constructor. Then you can use the various methods on the URL class to access the different parts of the URL.
OK, I see that this isnt what you meant. You could probably use a regular expression, but using substring is the easiest method. Why dont you want to use it?
If the string will always be similar, a quick-fix would be to use a StringTokenizer on the single quote. Then you would simply take the 2nd token.
