java - 当我按下连续按钮时，为什么它不连续运行？

Question

public class TestingActivity extends Activity implements View.OnClickListener
{
ScheduledThreadPoolExecutor scheduler = new ScheduledThreadPoolExecutor(1);

ScheduledFuture now = null;
public void onCreate(Bundle savedInstanceState)
{
    //oncreate
}
public void rollthedice()
{
//rollthedice
}


 public void onClick(View view)
{

    Runnable runner = new Runnable()
    {
        public void run()
        {
            rollthedice();
        }
    };


    if(view.equals(continuous))
    {
    if(now == null)
        now = scheduler.scheduleAtFixedRate(runner, 0, 250, TimeUnit.MILLISECONDS);
    else
        return;
    }
    if(view.equals(stop))
    {
        if(now != null)
        {
            now.cancel(true);
            now = null;
        }

        else
            return;
    }
    if(view.equals(roll))
        rollthedice();
    if(view.equals(exit))
        System.exit(0);
}

我在 Java 应用程序中使用它并且工作正常，我将它放入 android 项目但它不起作用我希望连续按钮连续运行 rollthedice() 并停止按钮停止它然后连续再次启动它并且来回停下

您确定执行了 onCLick 吗？你打电话了吗

continuous.setOnClickListener(this);
stop.setOnClickListener(this);

等等？
