Android Recycle View LogCat:找不到方法

Question

我使用Android支持库中的RecyclerView.在使用Android 4.1.2(API 16)的三星Galaxy S2上运行时,一切正常但在Logcat中我看到了消息:

我应该担心这个消息吗？

Answer 1

看看这个答案/sf/answers/1302010951/

基本上，您没有调用正确的方法。您必须调用相应的“支持”方法。

例如。从 v14 调用 getActionBar() 而不是从 v7 调用 getSupportActionBar() 将导致此问题。

请确保您致电支持方法，此错误将会消失。
