关于对不规则区域填充源代码运行的问题

Comece executando o exemplo Android com quatro e depois cinco itens na layer_list, concentrando-se em @drawable/eel e na inflação de Left_shoe na linha 88 de MainActivity.java. Compare os stack traces resultantes e o uso de recursos; considera-se concluído quando a falha do quinto item e o aviso vermelho de recurso forem reproduzidos e sua causa for identificada.

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！
