change Fragment View

问题

I have an app with fragments. It works fine.

One of the fragments has a button, and when pressed I want to change the view.

public class BikeRecap extends Fragment {

public static Activity activity;
public static Context context;


/** Called when the activity is first created. */


public View onCreateView(LayoutInflater inflater, ViewGroup container,Bundle savedInstanceState) {

    activity = getActivity();
    context = activity.getApplicationContext();

    View view = inflater.inflate(R.layout.bike_recap, container, false);        

    ImageButton details = (ImageButton) item.findViewById(R.id.details);


    details.setOnClickListener(new OnClickListener() {
          @Override
          public void onClick(View v) {
              OpenNewView();
          }
    });

    return view;
}

OpenNewView() should change the view, so, the user is in the same tab, but the content is different

Is it possible?

回答1:

You can't have a fragment inside a fragment.

Try this code:

FragmentManager fragmentManager2 = getFragmentManager();
FragmentTransaction fragmentTransaction2 = fragmentManager2.beginTransaction();
DetailFragment fragment2 = new DetailFragment();
fragmentTransaction2.addToBackStack("abc");
fragmentTransaction2.hide(BikeRecap.this);
fragmentTransaction2.add(android.R.id.content, fragment2);
fragmentTransaction2.commit();

回答2:

I think you can, pretty easily, do what you are trying to do. If OpenNewView is implemented by the Activity, instead of by the fragment:

getActivity().openNewView(...)

... then the Activity can easily replace the current fragment with a new one, using the standard transaction mechanism.
