Java - 在运行时更改 Timer 的持续时间

Question

我有一个Timer，我安排了一个TimerTask 与delay 0 和period 150。 现在我想更改period，但Timer 已经在运行。 我现在如何更改period？

private int penultimateStep = 1;
private int lastStep = 1;
private Timer move = new Timer();
private TimerTask movePlayer = new TimerTask(){
    public void run(){
        //Schritte ändern
        if(lastStep==3){
            lastStep = 2;
            penultimateStep = 1;
        }
        else if(lastStep==1){
            lastStep = 2;
            penultimateStep = 3;
        }
        else if(lastStep==2){
            if(penultimateStep==1){
                lastStep = 1;
                penultimateStep = 3;
            }
            else if(penultimateStep==3){
                lastStep = 3;
                penultimateStep = 1;
            }
        }
    }
};


...

move.schedule(movePlayer, 0, 150);

检查这两个链接。此问题可能与上述任何一个问题重复。

所以你可以修改你的代码如下：

private int penultimateStep = 1;
private int lastStep = 1;
private Timer move = new Timer();

class MovePlayer extends TimerTask {
   public void run(){
       //Schritte ändern
       if(lastStep==3){
           lastStep = 2;
           penultimateStep = 1;
        }
        else if(lastStep==1){
            lastStep = 2;
            penultimateStep = 3;
        }
        else if(lastStep==2){
            if(penultimateStep==1){
                lastStep = 1;
                penultimateStep = 3;
            }
            else if(penultimateStep==3){
                lastStep = 3;
                penultimateStep = 1;
            }
        }
    }
}


...

move.schedule(new MovePlayer(), 0, 150);

干杯。
