Multiple random number results

Currently working in Android Studio and running into a little trouble. Trying to get my rollScore button to roll over and over. At this point it "rolls" once and stops. I've tried a for loop and while loop and unable to get it to allow multiple "rolls".

public class GameScreen extends AppCompatActivity {

    private Button rollButton; // Roll button being declared as a variable
    private TextView rollScore; // Text view being declared as a variable
    private TextView totalSCore; //
    private int mCounter = 0;
    private int totalRuns = 0;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_game_screen);

        Random randomGenerator = new Random();
        final int randomInt = randomGenerator.nextInt(7) + 1;

        rollButton = (Button) findViewById(R.id.rollButton);
        rollScore = (TextView) findViewById(R.id.rollScore);
        totalSCore = (TextView) findViewById(R.id.totalScore);



        rollButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                    rollScore.setText(Integer.toString(randomInt));
                    mCounter++;

            }
        });

    }
}
