我在使这个库工作时遇到了一些麻烦。有问题的库是PullToRefresh，根据Android Studio，库中存在一些文件错误导致它无法正常工作。该项目可以正常编译，但一旦它试图在我的设备上运行它就会显示“已停止工作”，LogCat会发出一些有关LayoutInflater不正确的信息。其他人有这个工作正常，所以我怀疑这是有错误的图书馆，虽然有人可以帮我解决这个问题，我将不胜感激。我有actionbarsherlock被用作库，它工作得很好，我尝试删除actionbarsherlock只是为了看看是否是问题，错误仍然发生。
这就是android studio所说的无法使用库的原因。如果需要，请求logcat。
