Question

是否赞扬从logcat获取更长的错误跟踪？例如，我在下面得到错误跟踪，但显然它不足以指出问题所在：

根据经验，你可以从上到下阅读，直到你发现一个你认识的类是你的，而不是在android内部。

在堆栈跟踪中，您可以找到此行

E/AndroidRuntime: FATAL EXCEPTION: main Process: com.site.pkg, PID: 10527 
android.view.InflateException: Binary XML file line #6: Binary XML file 
line #6: Error inflating class fragment at 
android.view.LayoutInflater.inflate(LayoutInflater.java:551) at 
android.view.LayoutInflater.inflate(LayoutInflater.java:429) at 
com.site.pkg.MainActivity$Adapter.onCreateViewHolder(MainActivity.java:62) 
at

其中有趣的部分是MainActivity$Adapter.onCreateViewHolder(MainActivity.java:62)

因此，您应该在MainActivity.java 62行开始调查。

但在您的情况下，您遇到此错误Error inflating class fragment at android.view.LayoutInflater.inflate(LayoutInflater.java:551)。很可能在您试图膨胀的片段布局中出现了问题。

因此，请检查您的布局xml文件，查找错误，也许您正在尝试添加一个已损坏或不存在的自定义窗口小部件（当然只是猜测）。

希望我至少指出了正确的方向。

从logcat
