我试图在玩家获胜或失败时重置玩家的积分值，但我无法找出使用当前代码的最佳接近方法。我曾尝试在$dateTimeObject = \DateTime::createFromFormat('G:i', '9:30');
$dateTimeObject->format('H:i');
时重置pointValue.setText("0")，但只是将字符串设置为＆＃34; 0＆＃34;并且round == 0永远不会重新初始化。我还尝试将point和win布尔值设置为false，在won或lost if语句中设置lose或win，然后在设置lose = true的{{1}}方法的结尾。我的尝试都没有奏效，我可能会过度思考。对于那些不知道怎么玩掷骰子的人：如果第一次投掷的总和是4,5,6,8,9或10，那么这个总和就成了玩家的“点”。要获胜，玩家必须继续滚动骰子直到点值滚动。在滚动点之前，玩家通过滚动7来输掉。
以下是我的MainActivity中使用上面提到的失败布尔尝试的代码
rollClicked()我将代码全部包含在内，以便您可以看到我的声明和point = 0方法，但问题出在public class MainActivity extends Activity

答案 0 :(得分：0)
我想我有正确的想法创建一个布尔值，但我没有使用两个布尔值，而是简化了一些东西并创建了一个布尔值。我重置点的原始if语句没有重置该回合或包含rounds++计数器，我没有定义我的else语句（或者在这种情况下，如果{{1}会发生什么}或win = false）。
旧的重置点if语句：
lose = false新的重置点if语句：
rounds++;
// reset point if player wins or loses
if (win = true){
point.setText("0");
} else if (lose = true){
point.setText("0");
}
以下是整个// reset point if player wins or loses else keep playing
if(resetPointValue == true) {
rounds = 0;
pointValue = 0;
}
else {
rounds++;
}
方法：
rollClicked()这绝对是一种过度思考和过度复杂化的案例。
