Generating random index for array

I'm a beginner at android and am working on my first app. I chose a tutorial using the google Places api and worked through it. Afterwards I decided I wanted to add a button that would choose a restaurant at random from the results. The app runs and I get no errors, testing on my galaxy tab 2. However when I click the Random button on the app, all that is displayed is the first restaurant in the list. Any help is much appreciated.

btnGetRand = (Button) findViewById(R.id.btn_get_rand);

    btnGetRand.setOnClickListener(new View.OnClickListener() {

        public void onClick(View arg0) { 
            Time t = new Time();
            t.setToNow();
            Random randomGenerator = new Random(t.toMillis(false));
            int count = nearPlaces.results.size();
            int r = randomGenerator.nextInt(count);
            int id = nearPlaces.results.indexOf(r);
            lv.performItemClick(lv, r, id);             
        }
    }); 

    lv.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            String reference = ((TextView) view.findViewById(R.id.reference))
                               .getText().toString();

            Intent in = new Intent(getApplicationContext(),
                    SinglePlaceActivity.class);
            in.putExtra(KEY_REFERENCE, reference);
            startActivity(in);
        }
    });
