推荐答案

使用 getSupportFragmentManager（），或者从你拥有的（ android.support.v4.app）中更改 FragmentManager 的 import .FragmentManager ）到 android.app.FragmentManager 。

Use getSupportFragmentManager(), or change the import for FragmentManager from what you have (android.support.v4.app.FragmentManager) to android.app.FragmentManager.

您需要持续使用无论是本地类还是后端。您无法混搭。

You need to consistently use either the native classes or the backport. You cannot mix and match.
