Keep a class member and save your result in it: 

class listener implements RecognitionListener{

String result; 

   public void onResults(Bundle arg0){
      ArrayList<String> matches = arg0.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
          result = matches.get(0);
   }
}

or just call another method of your class from within the onResult method: 

class listener implements RecognitionListener{

String result; 

   public void onResults(Bundle arg0){
      ArrayList<String> matches = arg0.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
          doSomethingWithResult(matches.get(0));
   }
}

class Listener implements RecognitionListener {

   ....

   public String onResults(Bundle arg0) {
      ArrayList<String> matches = arg0.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
      return matches.get(0);
   }

}

the above method definition works like so:

<access modifier> <return type> <method name>(<argument type> <argument name>)

Then the method can return a type of <argument type>

If the return type must be void then you can do something like this:

class Listener implements RecognitionListener {

    private String match = null;

    ....

    public void onResults(Bundle arg0) {
       ArrayList<String> matches = arg0.getStringArrayList(SpeechRecognizer.RESULTS_RECOGNITION);
       this.match = matches.get(0);
    }

    /**
     * Get the match
     * can return null if onResults not called or matches.get(0) == null
     */
    public String getMatch() {
        return match;
    }

}
