它意味着聆听者无效。
原标题:What does it means when the listener is null

我读过一些法典,人们使用类似的东西。

view.setOnLongClickListener(null);

它意味着什么? 为什么有人使用?

就是这样。

view.setOnLongClickListener(new OnLongClickListener() {

    public boolean onLongClick(View v) {
        return true;
    }
});

这肯定与第二次选举一样,后者指派一位听众来控制在你对你的看法进行长时间点击时会发生的情况。
