Вот xml разметка:

В классе GameActivity:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game);
mIntent = getIntent();
mStringDifficultyMode = mIntent.getStringExtra(Constants.KEY_INPUT_VALUE_WHEN_CALLED_GAME_ACTIVITY);
initViews();
if (mButtons[0][0].getText().equals("")) {
mTextView.setText("Работает!");
}
}
private void initViews() {
