as a poor man，
我会说今天我不知不觉就遇到了这个问题了吗？java.lang.RuntimeException: Binary XML file line #20：You must supply a layout_width attribute.其实讲真一眼看上去真发现不了什么问题，因为我哪里去找Binary XML这个文件呢？根本就木有啊，最后度娘了半天发现一个可能的比较好的办法就是：
乖乖去看你的所有xml文件，然后你会发现有可能你的Imageview忘了写结束标签，或者某些地方没有写LayoutWidth这样的问题，毕竟其实Eclipse等编译器有时候是检查不出这样的错误的！
