.replace(R.id.container, new User()).commit();/The method replace(int, Fragment) in the type FragmentTransaction is not app

提示错误：The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, MyFragment)

 getFragmentManager().beginTransaction()
                 .replace(R.id.container, new User()).commit();

Fragment Activity导入的库不一样，导入一样的即可。
