Using two different layouts for child items in ExpandableListView

Question

I\'m trying to do the ExpandableListView to use two different layouts depending on item type. At this time I made basic functionality except one thing: after se

I'm pretty sure that you are not returning the good child values when convertView != null on your getChildView method. Try to set your values after your condition, like that :

TextView textView = null;

if (convertView == null) {
     LayoutInflater inflater = (LayoutInflater)getSystemService(getBaseContext().LAYOUT_INFLATER_SERVICE);
     int itemType = getChildType(groupPosition,childPosition);
     String myText = childData.get(groupPosition).get(childPosition).get("chapter");

     switch (itemType) {
         case 0:
             convertView = inflater.inflate(com.oleg.mart.foreign.R.layout.child_row_notlast, null);
             break;
         case 1:
             convertView = inflater.inflate(com.oleg.mart.foreign.R.layout.child_row, null);
             break;
    }
}

textView = (TextView)convertView.findViewById(com.oleg.mart.foreign.R.id.NChild);
textView.setPadding(30,20,30,20);
textView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 15);
textView.setText(Html.fromHtml(myText));

If you still have a problem with that, please put a comment on my answer to tell me and I will see what I can do.

Use HeterogeneousExpandableList . (https://developer.android.com/reference/android/widget/HeterogeneousExpandableList.html) It provides feature to have different header/child views in expandable list view.and also maintains its reuse.
