Question

i made a custom animation a sliding menu (like fb) and i have to insert a listview in the sublayout. But the listview is in a different class which is parsed through json using a lazyadapter.

This is my MainActivity

package com.android.appslu;

My question is how to display the listview from JSONParsingActivity in the sublayout of MainActivity.

Im new to android programming.... Plz help..

Thanks in advance..

Was it helpful?

Solution

Extend your JSONParsingActivity with ListFragment. Load JSONParsingActivity in your main Activity.

Updated with Code

FragmentManager fragmentManager = getFragmentManager()
FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();

You can then add a fragment using the add() method, specifying the fragment to add and the view in which to insert it.

ExampleFragment fragment = new ExampleFragment();
fragmentTransaction.add(R.id.fragment_container, fragment);
fragmentTransaction.commit();

Please refer this link ,everything about fragment is explained here.

This is the way you can set UserInterface in fragment. Solution for First one 1.

public static class ExampleFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    return inflater.inflate(R.layout.example_fragment, container, false);
}
}

Solution for Second problem.

  LazyAdapter(getActivity(), ArrayList<HashMap<String,String>>)
