我的Android應用猜錯遊戲中的錯誤

Question

我希望有人可以幫助解決這個問題。我有Android的下面的猜謎遊戲應用程序。

什麼它應該做的是，當用戶猜錯了三次，它有說，他們已經猜到錯三次，答案是alertdialog ....

它真正做到這一點沒問題，但問題是，如果用戶在第三次嘗試時得到了答案，它仍然會提示警告，說他們錯了三次，而不是警告，告訴他們他們做對了。除了這一次，這兩種警報都能正常工作。

應用程序中的其他所有內容都按我的需要工作。

任何想法的人？

感謝

Answer 1

當你在該行的if語句的內部;

if (attempts++ > maxAttempts) 

確保您maxAttempts是2而不是1。因爲只是你應該嘗試它3次，它應該是0 , 1 and 2 ..

所以，你應該讓你的行

final int maxAttempts = 2;
