看着貌似很迷茫，因为一大串错误
不过事实上也就标记颜色的三行（当然我是以一个初学者的态度说只错了这三行）
告诉我可能是名字冲突，可是把整个工程的layout文件都看了一遍，都没发现有冲突的名字
然后注意到了蓝色那一行，具体内容对应如下：
view4 = lf.inflate(R.layout.layout4,null);
这股风其实也没有错
其实我一开始应该就注意到绿色文字那一行（可惜经验不足 啊），java.lang.OutOfMemoryError: bitmap size exceeds VM budget，什么意思呢，图片尺寸太大啊，所以到res下面的drawable改了图片尺寸就OK了，欣慰啊
总结如下：
1、名字冲突；
2、布局文件出错；
