Question

我将此代码作为方法：

String resultTimeString = ct.toString()
    if(resultTimeString.length() == 2 ){
        resultTime1ASCII = resultTimeString.charAt(0);
        resultTime2ASCII = resultTimeString.charAt(1);
        resultTime1 = (int)resultTime1ASCII - 48;
        resultTime2 = (int)resultTime2ASCII - 48;
        resultTime = resultTime1 + resultTime2;
    }
    else{
        resultTime1ASCII = resultTimeString.charAt(0);
        resultTime1 = (int)resultTime1ASCII - 48;
        resultTime = resultTime1;
    }
    punkty = punkty * resultTime;
    //Globals.setScore(punkty);
    ct.cancel();

问题在于计算。最终得分（“punkty”）不是多重punkty和resultTime，我不知道为什么。变量 punkty 被定义为给出一个好答案的分数。

计时器从60减少到0。

Answer 1

你说最终得分总是为0。

唯一可能发生这种情况的方法是将punkty初始化为0。

每次，它乘以0，并保持为0.

您应该将punkty初始化为1。那么你的代码就可以了。

@Hackerdarshi，也许我会告诉你所有代码：
