add ListFragment with FragmentTransaction is not supported?

问题

I have a ListFragment:

public class MyListFragment extends ListFragment{
      ...
}

In order to use Fragment in my Android 2.1 API 7 project, I use the support package. (Everything has configured for the support package)

In my host Activity looks like:

import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentTransaction;

public class FragmentNavActivity extends FragmentActivity {

   @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...

        FragmentManager fMgr = getSupportFragmentManager();  
        FragmentTransaction fTrans = fMgr.beginTransaction();

        MyListFragment myListFragment = new MyListFragment();

        fTrans.add(android.R.id.content, myListFragment).commit(); //problem here

        ...
    }

}

The problem is that the FragmentTransaction 's .add(int, Fragment) method accept arguments with the second one of type Fragment, however, I have ListFragment which is not acceptable by this method.

So, how to add ListFragment with FragmentTransaction ?

回答1:

Maybe the problem is because you are importing android.support.app.ListFragment

回答2:

Try using nested fragments. In that way you can wrap your ListFragment inside a Fragment, which you can use in your FragmentTransaction

Nested Fragments
