关于对不规则区域填充源代码运行的问题

首先运行 Android 示例，先在 layer_list 中使用四个项目，然后使用五个项目，重点关注 @drawable/eel 以及 MainActivity.java 第 88 行对 Left_shoe 的 inflate。比较产生的堆栈跟踪和资源使用情况；当第五个项目的失败和红色资源警告都被复现，并且其原因已确定时，即表示完成。

您好！
我在您的博客上看到了http://blog.csdn.net/lmj623565791/article/details/45954255这篇文章，我下载了您的源代码，发现在调用background:@drawable/eel的时候会出现一个红色感叹号，但是没有提示：

再点击红色符号之后会跳到：

之后我按照您的代码自己写了一份，同样有这个感叹号，并且，在我在layer_list中放4个item时，
我的程序就能运行：

但是我在里面放置五项的时候，

就会报错，错误信息在底下：

我测试过这和图片没有关系，是一旦超过4个就会报错。我的android studio 版本是1.5.1
请问这是因为什么导致的呢，我该怎么改正？希望能得到您的帮助！
