本文介绍了如何在Android TV应用中实现焦点按钮长按启动连续快进，长按结束则停止快进的功能。通过ScheduledExecutorService定时发送消息控制快进，并在按键抬起时关闭定时任务。

最近做播放器，有个需求，当焦点在一个按钮上，长按确认键执行连续快进，长按结束停止快进

private boolean isLongPress;
private ScheduledExecutorService scheduledExecutor=Executors.newSingleThreadScheduledExecutor();
public static final int FASTFORWARD =124;
public static final int REWIND =125;

ivNextEpisode.setOnLongClickListener(new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        updateFastForward();//快进
        isLongPress = true;
        return true;
    }
});
ivNextEpisode.setOnKeyListener(new View.OnKeyListener() {
    @Override
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        if(isLongPress){
            if(event.getAction() == KeyEvent.ACTION_UP){
                stopForwardOrRewind();//停止快进
            }
        }
        return false;
    }
});

private void updateFastForward() {
     if(scheduledExecutor == null){
        scheduledExecutor=Executors.newSingleThreadScheduledExecutor();
    }
    scheduledExecutor.sc
