CountDownTimer琐事游戏得分 - Android电子（JAVA） [英] CountDownTimer trivia game score - Android (java)
问题描述
我有一个琐事游戏，显示10个问题，他们每个人都有10秒计时器。我有2个问题，无法正常工作。
首先，如果计时器耗尽的一个问题，它会显示下一个问题，但计时器没有复位。该textviews停留在时间到了！和经过时间：10000，而不是重新启动计时器上显示的新问题
。最后，检索结果页面上的正确得分未在TextView中显示。百分比TextView中正确显示，但比分的TextView显示android.widget.TextView@416473c或一些其他随机的内存位置。
该项目从来没有崩溃只是函数不正确。任何code结构或其他建议是非常AP preciated！这是我的第一个Android手机应用的尝试，我慢慢地strugglingly通过它。然而，享受它！ ：）

从所有code，这是什么，我认为正在发生的事情。
首先，如果计时器耗尽的一个问题，它会显示下一个问题，但计时器没有复位。该textviews停留在时间到了！和经过时间：10000，而不是重新启动计时器上显示的新问题
。这似乎是由于你没有时间之后你的
timerHasStarted变量设置为false，用完了，所以我会设置为false可能当您加载你的下一个问题或后显示结果。
最后，检索结果页面上的正确得分未在TextView中显示。百分比TextView中正确显示，但比分的TextView显示android.widget.TextView@416473c或一些其他随机的内存位置。
这是因为你设置您的问与答变量TextView的和得到的ID。你需要像
q1.getText（）。的toString（）您有相同名称的比分多个变量。因此，将其更改为
TextView的score2 =（的TextView）findViewById（R.id.score）;
字符串s =+得分;
score2.setText（多个）;I have a trivia game that displays 10 questions and they each have a 10 second timer. I have 2 problems that do not function correctly.
Firstly, If the timer runs out on a question, it displays the next question but the timer does not reset. The textviews stay at "Time's up!" and "Time Elapsed: 10000" instead of restarting the timer on the new question that is displayed.
Lastly, on the Results page the correct score is not displayed in the textview. The percentage textview displays correctly but the score textview displays "android.widget.TextView@416473c" or some other random memory location.
The program never crashes just functions incorrectly. Any code structure or other suggestions is much appreciated! This is my first android mobile app attempt and I am slowly and strugglingly through it. Yet enjoying it! :)

解决方案From all of that code, this is what I think is happening
Firstly, If the timer runs out on a question, it displays the next question but the timer does not reset. The textviews stay at "Time's up!" and "Time Elapsed: 10000" instead of restarting the timer on the new question that is displayed.
This appears to be due to you not setting your
timerHasStartedvariable to false after the time runs out so I would set that to false probably when you load your next question or after you show the results.Lastly, on the Results page the correct score is not displayed in the textview. The percentage textview displays correctly but the score textview displays "android.widget.TextView@416473c" or some other random memory location.
This is because you are setting your q variables to the textview and getting the id. You need something like
q1.getText().toString()You have multiple variables with the same name score. So change it to
TextView score2 = (TextView)findViewById(R.id.score); String s = "" + score; score2.setText(s);
