這個意思是說沒有找到根類載入器,然後我又往上看異常資訊,發現了貓膩
這個
Binary XML file line #15: Error inflating class com.bigkoo.convenientblanner.ConvenientBanner
然後我又看了下這個ConvinientBanner依賴已經匯入了,怎麼還報錯,好吧既然這樣,我把這個控制元件又寫了一遍
<com.bigkoo.convenientbanner.ConvenientBanner
android:layout_width="match_parent"
android:layout_height="200dp"
android:id="@+id/banner_cb"
app:canLoop="true"></com.bigkoo.convenientbanner.ConvenientBanner>
因為這個控制元件我是從別的Activity複製過來的,有可能導致R地址錯誤,改過果然沒事了
對這個問題,網上說重啟,也是可以,前提是你確保異常資訊你都排除掉了.我的異常解決了,可能大家都各不一樣,也有可能lib包未匯入等等,大家還是要細心.
