I have customized expandable list view showing in Navigation Drawer. I have a click listener in Adapter I would like to send click event from adapter to my activity or fragment. Is

Solution 1:

   public class CustomAdapter implements ExpandableListAdapter {

    Activity yourActivity
     public CustomAdapter(Activity yourActivity)
                    {

            this.yourActivity= yourActivity;

                }

    @Override
    public View getGroupView(int position, boolean isExpanded, View convertView, ViewGroup parent) {

        if (convertView == null) {
            convertView = inflater.inflate(R.layout.menu_item, parent, false);
        }

        TextView text = (TextView) convertView.findViewById(android.R.id.text1);
        text.setText(items.get(position).getName());
        ImageView imageView = (ImageView) convertView.findViewById(R.id.imageIndicator);

        if (items.get(position).isHasChild() && items.get(position).getSubMenuItems().size() > 0)
            imageView.setVisibility(View.VISIBLE);
        else
            imageView.setVisibility(View.INVISIBLE);

        if (isExpanded)
            imageView.setImageResource(R.drawable.down);
        else
            imageView.setImageResource(R.drawable.next);

        return convertView;
    }

    @Override
    public View getChildView(final int childPosition, int groupPosition, boolean isExpanded, View convertView, final ViewGroup parent) {

        View view = convertView;

        if (view == null) {
            view = inflater.inflate(R.layout.expandable_list, parent, false);
        }
        ExpandableHeightListView childList = (ExpandableHeightListView) view.findViewById(R.id.childList);
        childList.setAdapter(new CustomAdapter(context, items.get(childPosition).getSubMenuItems()));
        childList.invalidate();
        parent.invalidate();

        final ExpandableHeightListView list = childList;
        childList.setOnGroupExpandListener(new ExpandableListView.OnGroupExpandListener() {

            int previousItem = -1;

            @Override
            public void onGroupExpand(int groupPosition) {
                ArrayList<eMenuItem> tempItems = items.get(childPosition).getSubMenuItems();

                if (tempItems.get(groupPosition).getSubMenuItems().size() == 0) {
                     yourActivity.onYourClick(groupPosition);
                } else {
                    Toast.makeText(context, "Clicked on " + tempItems.get(groupPosition).getName(), Toast.LENGTH_SHORT).show();
                }

                if (groupPosition != previousItem)
                    list.collapseGroup(previousItem);

                previousItem = groupPosition;
                list.invalidate();
                parent.invalidate();
            }
        });
        return view;
    }
}

//Your Fragment

    public class yourActivity extends FragmentActivity{
            public void onYourClick(int groupPosition){
            }
