如何添加时间倒计时? [英] How to add time to countdown timer?
问题描述
我知道有这样一个职位,但它并没有回答这个问题清楚了。 我有一个小游戏,你点击一个头并将其移动到一个随机位置,你会得到+1得分。同时有一个计时器从60000(60秒)开始递减计数和显示在下面。 我怎样才能使它所以每当头部被窃听,它增加了一个第二次计时?
I know there is a post like this but it does not answer the question clearly. I have a little game where you tap a head and it moves to a random position and you get +1 to score. Meanwhile there is a timer counting down from 60000 (60 seconds) and displaying below. How can I make it so whenever the head is tapped, it adds a second to the timer?
new CountDownTimer(timer, 1) {
public void onTick(long millisUntilFinished) {
textTimer.setText("Timer " + millisUntilFinished/1000);
}
public void onFinish() {
Intent intent = new Intent(MainActivity.this, Gameover.class);
startActivity(intent);
}
}.start();
和在onClickListner事件我有:
and in the onClickListner event I have:
timer=timer+1000;
目前,它不工作,在没有时间增加的点击。
It currently doesn't work as in there is no time added on the click.
任何帮助将是AP preciated:)
Any help would be appreciated :)
推荐答案
您不能更改计划的计时器的时间。实现你正在尝试做的唯一方法是通过取消计时器,并建立一个新的。
You can't change the time of a scheduled timer. The only way to achieve what you are trying to do is by cancelling the timer and setting up a new one.
public class CountdownActivity extends Activity implements OnTouchListener{
CountDownTimer mCountDownTimer;
long countdownPeriod;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_countdown);
countdownPeriod = 30000;
createCountDownTimer();
}
@Override
public boolean onTouch(View v, MotionEvent event) {
if (mCountDownTimer != null)
mCountDownTimer.cancel();
createCountDownTimer();
return true;
}
private void createCountDownTimer() {
mCountDownTimer = new CountDownTimer(countdownPeriod + 1000, 1) {
@Override
public void onTick(long millisUntilFinished) {
textTimer.setText("Timer " + millisUntilFinished / 1000);
countdownPeriod=millisUntilFinished;
}
@Override
public void onFinish() {
Intent intent = new Intent(MainActivity.this, Gameover.class);
startActivity(intent);
}
};
}
}
