下边会贴出LinkedList随机访问的源代码,也就是这里为什么选择1000000中间数的原因。 2.Java栈区和堆区都是有限的,list那里如果一次添加5000000个item就会内存溢出 (Exception in thread "main"java.lang.OutOfMemoryError: Java heap space)。 但有点奇怪,不是new了在内存堆区吗?内存堆区也会爆~~ 下边是LinkedList...

ListView中Item的多布局显示,需要用到了getviewtypecount和getItemViewType这两个重写方法,但是做完后出现了如下提示错误: java.lang.ArrayIndexOutOfBoundsException: (数组越界) 搜了原因,居然是getItemViewType这里里面返回的Type必须是从0开始的,如果getviewtypecount等于2,那么getItemViewType返回的数值是从0~1的常数。简...

();后,就抛错了,根据日志分析,错误日志记录的一般是java.lang.ArrayIndexOutOfBoundsException: -68,后面是一个-128范围内的负数,并且根据时间逐渐增大,比如到java.lang.ArrayIndexOutOfBoundsException: -2,然后java.lang.ArrayIndexOutOfBoundsException: -1,然后又轮回到java.lang.ArrayIndexOutOfBoundsException:...
