Question

well i´m trying to create a ExpandableListView like Spotify it does… But i don´t have any idea how do disable the LinearLayout to act like a button (Expand the list) I have created a image which should describe what i like. I like to have the possibility to handle a click on the text / image (parent) as a normal interaction. A click on the right button should expand the list like in Spotify…

This is the onCreate from the ChannelList which extends ListFragment. It stores the data and generate a new Adapter if the Fragment is called.

@Override   
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) 
{                               
    m_ListView = new ExpandableListView(getActivity());
    m_ListView.setId(android.R.id.list);

    m_ListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
    m_ListView.setMultiChoiceModeListener(m_MultiChoiceModeListener);

    m_ChannelListAdapter = new ChannelListAdapter(getActivity(), this);
    m_ListView.setAdapter(m_ChannelListAdapter);
    m_ListView.setGroupIndicator(null);
    m_ListView.setOnGroupClickListener(this);

    return m_ListView;
}

On the Adapter i have the getGroupView Method which look like:

public View getGroupView(int i, boolean b, View view, ViewGroup viewGroup) {

    if (view == null) 
    {
        view = inflater.inflate(R.layout.layout_channelwithimage, viewGroup, false);
    }

    TextView textView = (TextView) view.findViewById(R.id.labelwithimage);
    textView.setText(getGroup(i).toString());

    ImageButton imbu = (ImageButton) view.findViewById(R.id.imageButton);
    //imbu.setOnClickListener(this);    
    imbu.setFocusable(false);

    return view;
}

So if i register the ImageButton in the adapter it will call the onClick from the adapter. But in the onClick i do not know which group was clicked… If i do not register the button on any listener it will not call the onGroupClick from the ChannelList…
