Java中的計數器增量錯誤

Question

我正在開發一個應用程序來保持網球得分。一切工作正常，除了我的下面的代碼中的幾個問題。

1）我必須在每次啓動應用程序時按下RESET按鈕，因爲櫃檯不斷增加並且它在條件下工作。 2）無法關閉set1到7-5。 set1繼續從7-5增加到8-5,9-5等

任何幫助將不勝感激。

Answer 1

要獲得TextView的文字作爲String使用textViewCount1.getText().toString()和比較String的使用equals(...)代替==。

下面是一個例子：

if (CountB == 3 && textViewCount2.getText().toString().equals("40") && textViewCount1.getText().toString().equals("40")) { 
    textViewCount1.setText("AD"); 
    CountA--; 
}
