Code not working (Randomize Array)

Hey i wanted to ask for help since i dont know why my code is not working. Im new to android programming and wanted to ask for help.

public class MotivationalQuotesMenu extends Activity {

int [] images = {R.drawable.mem1, R.drawable.mem2, R.drawable.mem3};

public static int[] RandomizeArray(int[] images){
        Random rgen = new Random();  // Random number generator

        for (int i=0; i<images.length; i++) {
            int randomPosition = rgen.nextInt(images.length);
            int temp = images[i];
            images[i] = images[randomPosition];
            images[randomPosition] = temp;
        }

        return images;
    }

And then...

class loladapter extends ArrayAdapter<String> {
        Context context;
//class that shows a specific row in listview

        private loladapter(Context c, String[] titles, int imgs[]) {


            super(c, R.layout.singlerow, R.id.textView, titles);
            this.context = c;
            images = imgs;
        }

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            View row = inflater.inflate(R.layout.singlerow, parent, false);
            ImageView myimageie = (ImageView) row.findViewById(R.id.imageView);

            myimageie.setImageResource(images[position]);
            return row;

        }
    }

Random images wont show.. just the same array with the same order
