Android：在测验中添加分数和计时器，并使用新的随机值重置测验

Question

我想根据等级收集不同活动的分数和完成时间。我也想重置测验。每个级别都有5个问题：我希望我的代码应该看起来像附加图像。目前我能够改变5次问题。但不知道如何更新关卡和得分以及计时器，然后生成显示结果的文件，如级别，分数，时间

您可以使用android中的CountDownTimer来计算1分钟。像这样：

 new CountDownTimer(60000, 1000) {

     public void onTick(long millisUntilFinished) {
         mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
     }

     public void onFinish() {
         mTextField.setText("time is up!");
     }
  }.start();

最后（finish）你可以随心所欲。例如，更改片段，或设置新问题，或完成当前活动并开始新活动。
