title: Android regular expression - return matched string
body: <p>In my Android project I have a regular expression and a string, in which I should have the matched expression. The problem is, I've only found a <code>matches()</code> method, which returns boolean. Is there something, which returns only the matched string (for instance, if my string is "go to the shop at 12pm", I want to check if there is a time in this string (in this example - "12pm"), if it is - return it) ?
  Thanks in advance.</p>
