Class 倒数计时器未重置

Question

我有一个 class 倒数计时器，我想重置它，但是当它重置时它不会再次启动。基本上当计数器到达 0 （当状态为 "done" 时），设置 x = 1 然后在 activity 检查是否 x = 1 ，然后计数器重置。当调用 class 中的重置方法时，它显示它已重置但不会再次开始计数

定时器class:

public class countdown_timer {
private long pls;
private long millisInFuture;
private long countDownInterval;
private boolean status;
int x = 0;
public countdown_timer(long pMillisInFuture, long pCountDownInterval) {
    this.millisInFuture = pMillisInFuture;
    this.countDownInterval = pCountDownInterval;
    this.pls = pMillisInFuture;
    status = false;
    Initialize();
}
    public void Stop() {
    status = false;
}
    public int GetNumberX() {
    return x;
}

public void Reset() {
    millisInFuture = pls;
    x=0;
}
    public void Start() {
    status = true;
}

public void Initialize() {
    final Handler handler = new Handler();
    Log.v("status", "starting");
    final Runnable counter = new Runnable() {

        public void run() {
            long sec = millisInFuture / 1000;
            if (status) {
                if (millisInFuture <= 0) {
                    Log.v("status", "done");
                    x = 1;
                } else {
                    Log.v("status", Long.toString(sec) + " seconds remain");
                    millisInFuture -= countDownInterval;
                    handler.postDelayed(this, countDownInterval);
                }
            } else {
                Log.v("status", Long.toString(sec) + " seconds remain and timer has stopped!");
                handler.postDelayed(this, countDownInterval);
            }
        }
    };

    handler.postDelayed(counter, countDownInterval);
}

Activity 使用计时器 class:

mycounterup = new countdown_timer(startcard, 1000);
xup = mycounterup.GetNumberX();
if (xup == 1) {
   mycounterup.Reset();
   mycounterup.Start();

感谢您的帮助。

Answer 1

你应该改变你的Reset方法：

public void Reset() {
    millisInFuture = pls;
    x=0;
    Initialize();
}

Answer 2

尝试改变你的启动方法，还有一件事我不知道它是一个错字还是什么改变mycounter.Start(); 到 mycounterup.Start();

 public void Start() {
 status = true;
 Initialize();
}

保存 counter 状态，这样下次如果您必须暂停或恢复操作，您也可以这样做
