setOnCheckedChangeListener - android-listview

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

Answer 1

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

Answer 2

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.
