標籤:replace method package commit fragment
在最近新學fragment的時候出現了一個錯誤:
The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, MyFragment)建立fragment的時候
Fragment newfragment =new MyFragment();
fragmentTransaction.replace(R.layout.activity_main,newfragment ).commit();
提示錯誤:The method replace(int, Fragment) in the type FragmentTransaction is not applicable for the arguments (int, MyFragment)
