Try the following code:

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

    Button[] buttons = new Button[objectLength]; 
    buttons[0] = (Button)findViewById(R.id.buttonOne);
    buttons[1] = (Button)findViewById(R.id.buttonTwo);
    buttons[2] = (Button)findViewById(R.id.buttonThree);
    buttons[3] = (Button)findViewById(R.id.buttonFour);
    buttons[4] = (Button)findViewById(R.id.buttonFive);
    buttons[5] = (Button)findViewById(R.id.buttonSix);
    buttons[6] = (Button)findViewById(R.id.buttonSeven);
    buttons[7] = (Button)findViewById(R.id.buttonEight);
    buttons[8] = (Button)findViewById(R.id.buttonMid);
