我在让这个库工作时遇到了一些麻烦。有问题的库是 PullToRefresh，根据 Android Studio 的说法，库中存在一些文件错误，导致它无法正常工作。该项目可以很好地编译，但是一旦它尝试在我的设备上运行它，它就会显示“已停止工作”，并且 LogCat 会喷出一些关于 LayoutInflater 不正确的信息。其他人的工作正常，所以我怀疑是图书馆有错误，但如果有人能帮我解决这个问题，我将不胜感激。我已经将 actionbarsherlock 用作库并且它运行良好，我尝试删除 actionbarsherlock 只是为了看看这是否是问题并且错误仍然发生。
这就是 android studio 关于为什么不能使用该库的原因。如果需要，请索要 logcat。
