Exception on click group item about animatedexpandablelistview

[idunnololz]

Can you please post your expandablelistview structure (like layout for child and group views and how many types of child and or group views) ? Thanks

If you are testing using vanilla Android then line 495 in the relative layout source is
if (mLayoutParams.height >= 0) {
Which must mean that the layout params of a Relative Layout is null.

I'm used simple adapter
public class ExpListAdapter extends AnimatedExpandableListView.AnimatedExpandableListAdapter {

Context context;
ArrayList<String> groups;
ArrayList<ArrayList<String>> titles;

public ExpListAdapter(Context context, ArrayList<String> groups, ArrayList<ArrayList<String>> titles) {
    this.context = context;
    this.groups = groups;
    this.titles = titles;

}

@Override
public int getGroupCount() {
    return titles.size();
}

@Override
public Object getGroup(int groupPosition) {
    return titles.get(groupPosition);
}

@Override
public Object getChild(int groupPosition, int childPosition) {
    return titles.get(groupPosition).get(childPosition);
}

@Override
public long getGroupId(int groupPosition) {
    return groupPosition;
}

@Override
public long getChildId(int groupPosition, int childPosition) {
    return childPosition;
}

@Override
public boolean hasStableIds() {
    return true;
}

@Override
public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.start_parent, null);
    }
      TextView textGroup = (TextView) convertView.findViewById(R.id.tv_parent_size);
    textGroup.setText(groups.get(groupPosition));
    TextView textGroupnum = (TextView) convertView.findViewById(R.id.tv_parent_numbet);
    textGroupnum.setText(String.valueOf(groupPosition + 1));
    return convertView;
}

@Override
public View getRealChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) {
    if (convertView == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        convertView = inflater.inflate(R.layout.start_childer, null);
    }
    TextView textChild = (TextView) convertView.findViewById(R.id.tv_children_name);
    textChild.setText(titles.get(groupPosition).get(childPosition));
    return convertView;
}
@Override
public int getRealChildrenCount(int groupPosition) {
    return titles.get(groupPosition).size();
}
@Override
public boolean isChildSelectable(int groupPosition, int childPosition) {
    return true;
}

}

In my expandable list, I use one view type for group and and one for child view

In activie I'm use next code:
// In order to show animations, we need to use a custom click handler
// for our ExpandableListView.

    listView.setOnGroupClickListener(new ExpandableListView.OnGroupClickListener() {
        @Override
        public boolean onGroupClick(ExpandableListView parent, View v, int groupPosition, long id) {
            // We call collapseGroupWithAnimation(int) and
            // expandGroupWithAnimation(int) to animate group
            // expansion/collapse.
            if (listView.isGroupExpanded(groupPosition)) {
                listView.collapseGroupWithAnimation(groupPosition);
            } else {
                listView.expandGroupWithAnimation(groupPosition);
            }
            return true;
        }

    })

Instead of using LayoutInflater.inflate(int layoutId, ViewGroup parent) try using LayoutInflater.inflate(int layoutId, ViewGroup root, boolean attachToRoot).

So replace inflater.inflate(R.layout.start_parent, null); with inflater.inflate(R.layout.start_parent, parent, false); and inflater.inflate(R.layout.start_childer, null); with inflater.inflate(R.layout.start_childer, parent, false);

Thank you very much! Did not pay attention(
