我的Android應用猜游戲中的錯誤

Question

我希望有人可以提供幫助。 我有以下針對Android的猜謎游戲應用程序。

它應該做的是，當用戶猜錯三遍時，它會顯示一個警告對話框，提示他們三遍猜錯了，答案是...。

它確實確實可以很好地解決問題，但是存在的問題是，如果用戶在第三次嘗試中得到正確的答案，它仍然會發出警告，指出他們錯了三次，而不是警告他們說過錯了。 。 除了這一次，兩個警報都可以正常工作。

應用程序上的其他所有內容均按我的意願運行。

有任何想法嗎？

謝謝

                       randText = Integer.toString(ranNum);
                       textResponse.setText("");

    );

}

}

Answer 1

當您在此行的if語句中時；

if (attempts++ > maxAttempts)

確保您的maxAttempts是2而不是1 。 因為您只需嘗試3次，所以它應該是0 , 1 and 2 ..

所以你應該做你的線

final int maxAttempts = 2;
