If you want it on List Item Click

Fragment A:

public class FragmentA extends ListFragment {

OnItemSelectedListener mListener;

...
// Container Activity must implement this interface
public interface OnItemSelectedListener {
    public void onItemSelected(int position);
}
...

@Override
public void onAttach(Activity activity) {
    super.onAttach(activity);
    try {
        mListener = (OnItemSelectedListener) activity;
    } catch (ClassCastException e) {
        throw new ClassCastException(activity.toString() + " must implement OnItemSelectedListener");
    }
}

@Override
public void onListItemClick(ListView l, View v, int position, long id) {

    mCallback.onItemSelected(position);

    }   
}

ContainerActivity:

public class ContainerActivity extends FragmentActivity 
    implements FragmentA.OnItemSelectedListener
{

//...



public void onItemSelected(int Position/*pass anything which u want*/) 
    {

        SecondFragment second_fragment = (SecondFragment) getSupportFragmentManager().findFragmentById(R.id.fragmentB);

        if(second_fragment !=null)
        {
            second_fragment.UpdateUI(Position); 
        }

    }


 }

Second Fragment:

public class SecondFragment extends Fragment {

    ...
    public void UpdateUI(Position)
    {

    }

}

Hope this helps. On click of a Button inside each listitem might be bit difficult, but try the same approach. May be you have to write the interface declaration and call in your custom adapter.
