我的tic tac toe app有一个奇怪的问题。在实现绘制功能之前，一切都按预期工作。然后我点击它激活绘制消息的位置0。如果我不在我的网格中使用0位置它也可以。为什么＆＃34;它是平局＆＃34;激活然后我点击网格中的第一个空格？

Answer 1

在你的代码中setText方法调用至少一个counterState！= 2.尝试改变这样

boolean gameIsOver=true;
for (int counterState: gameState){
    if (counterState==2){
       gameIsOver =false;  
       break;
    }         
}
if (gameIsOver) {
    TextView winnerMessage =(TextView)findViewById(R.id.winnerMessage);
    winnerMessage.setText("It's a draw!");
    LinearLayout layout =(LinearLayout)findViewById(R.id.playAgainLayout);
                    layout.setVisibility(View.VISIBLE);
}
