尝试打开警报对话框时出现以下错误；
android.view.InflateException: Binary XML file line #8: Binary XML file line #8: Error inflating class <unknown>
Caused by: android.view.InflateException: Binary XML file line #8: Error inflating class <unknown>
Caused by: java.lang.reflect.InvocationTargetException
这以前都是可行的，我将 android：textColor =“？attr / colorText” 添加到TextView中以便于主题设置。我将此与我最后知道的工作版本进行了比较，并且xml是相同的。

我不知道是什么原因造成的。似乎没有任何形式的xml格式错误。跟踪此错误的任何帮助将不胜感激。
答案 0 :(得分：0)
如果有人遇到类似的问题，我可以在以下庄园中解决此问题。
我试图用以下代码向对话框充气： 视图view = layoutInflaterAndroid.inflate（R.layout.dialog_league，null）在添加主题首选项代码之前效果很好。
代替使用： layoutInflaterAndroid.inflate（R.layout.dialog_league，null）;
我使用了： View.inflate（此，R.layout.dialog_league，空）
此代码更改解决了我几天就遇到的问题。
我只是通过阅读以下帖子来解决这个问题的； android.view.InflateException: Binary XML file line #12: Error inflating class <unknown>
答案 1 :(得分：0)
我有同样的问题。 getApplicationContext（）改用{activityname}。此
