app需要兼容多种分辨率的设备，一般的情况下，布局文件，都会提供多套出来，供自动匹配。
但调试修改布局文件的情况下，经常会报如下错误：
android.view.InflateException: Binary XML file line #101: Error inflating class

提示信息上面，会指明是哪一个Activity对应的Layout出现了布局。
按照提示去查看该layout，会发现，没有哪里出问题。这就怪了。
其实仔细查看，就会发现，不同分辨率下面，该布局文件所引用的资源，是有缺失的。
当调试分辨率是1024x768的layout时，我们添加了一张图片，但是我们习惯性的只是放在该分辨率下面的资源文件夹下面，那么就导致了，当我用1280x800这样的设备跑程序时，出现上述的问题。
解决方法：
把所有分辨率下面的资源文件中，都更新掉刚做的修改。添加文件时，所有分辨率下面都添加，删除时，都删除。做到同进退，上面这样的问题就不会出现了。
附上其他类似bug的解决方法：

总结：
类似的XML错误，大部分都是因为资源文件的来回引用引起的。
只要留意资源文件的命名，引用，后缀等等，即可避免
