在類型FragmentTransaction的方法Add（INT，片段，字符串）是不適用的參數（INT，片段，字符串）

Question

我有這個問題..

The method add(int, Fragment, String) in the type FragmentTransaction is not applicable for the arguments (int, Fragment, String) 

使用內部的下面的代碼時FragenmtActivity

getSupportFragmentManager().beginTransaction().add(com.korovyansk.android.slideout.R.id.slideout_placeholder, ((Fragment)new CommentsMenuFragment()), "menu").commit(); 

其中CommentsMenuFragment實現：

public class CommentsMenuFragment extends Fragment { 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
     View view = inflater.inflate(R.layout.fragment_comment, container, false); 
     ListView lvComments = (ListView) view.findViewById(R.id.lvComments); 



     return view; 
    } 

} 

Answer 1

CHEC k如果您的CommentsMenuFragment從android.support.v4.app.Fragment擴展而不是android.app.Fragment。
