How to delete a random element from a ArrayList

I have an ArrayList and i want to do a random to get a element, delete that element and make another random without that deleted element. How can i do that? I had tried but it doesn't work.

Thanks.

MainActivity:

public class MainActivity extends AppCompatActivity {

    Button button;
    TextView textView;

    ArrayList<Integer> list = new ArrayList<Integer>();

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

        button = (Button)findViewById(R.id.button);
        textView = (TextView)findViewById(R.id.textView);

        list.add(0);
        list.add(1);
        list.add(2);
        list.add(3);

    }

    public void button(View view) {
        Random rand = new Random();
        int randomElement = list.get(rand.nextInt(list.size()));
        if (list.isEmpty()) {
            textView.setText("Empty");
        } else if (randomElement == 0) {
            textView.setText("Red");
            list.remove(randomElement);
        } else if (randomElement == 1) {
            textView.setText("Blue");
            list.remove(randomElement);
        } else if (randomElement == 2) {
            textView.setText("Yellow");
            list.remove(randomElement);
        } else if (randomElement == 3) {
            textView.setText("Green");
            list.remove(randomElement);
        }
    }
}
