1)ItemBuilder.kt第15行是什么代码，应该是这块导致的问题。 2）具体什么原因没有描述清楚，你看一下，是不是信息没有贴全呢。 3）是你做什么操作了导致的崩溃还是打开应用什么都不做，过一会儿就会崩溃呢？再详细的描述一下。祝：学习愉快

    class ItemBuilder { //不能使用hashMap，因为hashMap是无序的 private val mItems = LinkedHashMap<BottomTabBean, BottomItemFragment>() companion object{ internal fun builder():ItemBuilder{ return builder() } } 有问题的代码就是这个builder，程序只运行了，什么操作都没有，看日志有个java.lang.StackOverflowError: stack size 8MB，感觉返回值应该写成this，我试一下，这块循环调用了，导致了这个error
