如何添加一個onClickLIstener到我的代碼來執行我已經實現的方法

您好，這是我在堆棧溢出中的第一篇文章，我是一名完整的初學者，因此非常感謝您的幫助！如何添加一個onClickLIstener到我的代碼來執行我已經實現的方法

好的，所以我正在按照製作TicTacToe（nirtts和十字架）遊戲的教程在java中爲android和教程中的人在菜單中使重置遊戲按鈕，但是我想做一個實際的按鈕下游戲區。我已經添加了按鈕（請參閱XML的底部），它們已經是一種重置遊戲的方法，所以我需要幫助弄清楚在java中如何以及在哪裏添加代碼，以便當我單擊其中一個按鈕時，它會重置爲我的遊戲（清除棋盤）提前謝謝！

如果你的按鈕的id是btnReset，在java文件的上面下面一行如下：

 AICount  = (TextView) findViewById(R.id.computerCount);

添加以下行

Button btnReset=(Button)findViewById(R.id.btnReset); 
    btnReset.setOnClickListener(new OnClickListener() { 

     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      //write the reset code here 

     } 
    });

如矗立在你按鈕說明：

<Button 
android:id="@+id/newGameBtn" 
android:onClick="resetBoard" 
android:layout_width="fill_parent" 
android:layout_height="wrap_content" 
android:text="@string/newGame" />

，你需要在你的活動添加public void resetBoard(View view)方法的代碼重置您的遊戲
