setOnCheckedChangeListener

Question

I want to expand the group item when I check on it, but for some reasons I can't collapse the group item after it expands.

Can someone please tell me what I am doing wrong?

    public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

    final GroupHolder holder;
    final ViewGroup viewGroup = parent;

    if (convertView == null) {
        convertView = layoutInflater.inflate(R.layout.group_list, null);
        holder = new GroupHolder();
        holder.checkbox = (CheckBox) convertView.findViewById(R.id.cb);
        holder.imageView = (ImageView) convertView.findViewById(R.id.label_indicator);
        holder.title = (TextView) convertView.findViewById(R.id.group_title);
        convertView.setTag(holder);
    } else {
        holder = (GroupHolder) convertView.getTag();
    }

    holder.imageView.setImageResource(groupStatus[groupPosition] == 0 ? R.drawable.group_down: R.drawable.group_up);
    final Item groupItem = getGroup(groupPosition);

    holder.title.setText(groupItem.name);

    holder.checkbox.setOnCheckedChangeListener(new OnCheckedChangeListener() {

        public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
            if (!ALL_CHECKED) {

                ArrayList<Item> childItem = getChild(groupItem);                                        
                for (Item children : childItem)
                    children.isChecked = isChecked;
                }               

            groupItem.isChecked = isChecked;
            // TODO Auto-generated method stub
            if(groupItem.isChecked)
            ((ExpandableListView) viewGroup).expandGroup(groupPosition);

            notifyDataSetChanged();
            new Handler().postDelayed(new Runnable() {

                public void run() {
                    // TODO Auto-generated method stub
                    if (ALL_CHECKED)
                        ALL_CHECKED = false;
                }
            }, 10);

        }

    });
    holder.checkbox.setChecked(groupItem.isChecked);
    return convertView;
  }

//Below is the logcat for when I only put a check mark on group0:

08-19 07:49:08.860: D/group pos: 0
08-19 07:49:08.863: D/group pos: 0
08-19 07:49:08.887: D/group pos: 4

I noticed that it showed groupId0 & 4 when I ONLY clicked on group0

Edit: Re-wrote to make it clear for others to understand better

Try to debug .... what you find during debug please tell me.?? — DJhon, Aug 18 '14 at 04:26

I have one idea. First remove CheckBOx and try to collapse by this

    lv.setOnGroupExpandListener(new OnGroupExpandListener() {

@Override
public void onGroupExpand(int groupPosition) {
        if (lastExpandedPosition != -1
                && groupPosition != lastExpandedPosition) {
            lv.collapseGroup(lastExpandedPosition);
        }
        lastExpandedPosition = groupPosition;
}

});

If still getting any problem please ping me if not getting any problem then add view and view group

First of all, thanks a lot to Blue Green for trying to help. I figured it out after days of debugging. The reason that it didn't let me collapse the expanded group was

public View getGroupView(final int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {

AND

public View getChildView(final int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {

BOTH had final int groupPosition. This is why the expandablelistview doesn't know which groupPosition that I want to collapse. Furthermore, because of this, it printed out groupId0 & 4 when I ONLY clicked on group0.

ExpandalblelistView is very ^$^** hard to deal with for me. I hope this helps someone else.

Yup..sure... Enjoy.... When a GOLD burn in furnace then it show its brightness..... Enjoy your issues... — DJhon, Aug 20 '14 at 11:56
