How to check if a string contains url in java

Question

If I have a string like below :

String str = "Google is awesome search engine. https://www.google.co.in";

Now in the above string I need to check if the string contains any link or not. In the above string it should return true as the string contains a link.

The function should check www.google.com also as link. It should not dependent on http:// or https://

I have checked this link also What's the best way to check if a String contains a URL in Java/Android? But it is returning true only if the string contain url only and what I want is if a string contain link at any place, it should return true.

I want that string also which will match the pattern, so that I can set that in a textview in android and can make it clickable.

How can I do this, please help me.

The regex is

((http:\/\/|https:\/\/)?(www.)?(([a-zA-Z0-9-]){2,}\.){1,4}([a-zA-Z]){2,6}(\/([a-zA-Z-_\/\.0-9#:?=&;,]*)?)?)

You could split the string on spaces and then test each 'word' in the resultant array using one of the methods in the answer you linked to above.

String[] words = str.split(" ");
for (String word : words) {
    // test here using your favourite methods from the linked answer
}
