直接上代码

public class TouchFrameLayout extends FrameLayout {//继承啥viewgroup都行
    private OnLongClickListener longclickListener;

    public void setLongclickListener(OnLongClickListener longclickListener) {
        this.longclickListener = longclickListener;
    }

    public TouchFrameLayout(Context context) {
        super(context);
    }

    public TouchFrameLayout(Context context, @Nullable AttributeSet attrs) {
        super(context, attrs);
    }

    public TouchFrameLayout(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    long time = 0;

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        if (ev.getAction() == MotionEvent.ACTION_DOWN) {
            time = new Date().getTime();
            return super.onInterceptTouchEvent(ev);
        } else {
            long cureent = new Date().getTime() - time;
            if (cureent < 1000) {
                return false;
            } else {//大于1000视为长按
                longclickListener.onLongClick(this);//长按事件
                return true;
            }
        }
    }
}

代码中或者xml中初始化都可以

TouchFrameLayout contentLayout = itemView.findViewById(R.id.contentFrameLayout);
contentLayout.setLongclickListener(listener);//此处设置长按监听

View.OnLongClickListener listener = v -> {//使用view的长按监听接口
            //做你的事件处理
            return true;
};

 这样父view的长按事件就不会被seekbar挡住  seekbar中的点击拖拽依然可用哦
