Ich versuche das zu tunExpandableListView Je nach Artikeltyp können zwei verschiedene Layouts verwendet werden. Zu diesem Zeitpunkt habe ich grundlegende Funktionen mit einer Ausnahme erstellt: Nach Auswahl einer Gruppe in derlistviewwird der Text des untergeordneten Elements falsch angezeigt (der Text verschiedener Elemente ist gemischt)

Meineadapter Der Quellcode lautet:

SimpleExpandableListAdapter adapter = new SimpleExpandableListAdapter(
            this,
            groupData,
            com.oleg.mart.foreign.R.layout.group_row,
            groupFrom,
            new int[] { com.oleg.mart.foreign.R.id.Group },
            childData,
            R.layout.simple_list_item_1,
            childFrom,
            childTo)
{
    @Override
    public int getChildTypeCount() {
        return 2;
    }

    /*@Override
    public int getChildrenCount(int groupPosition)
    {
        return childData.get(groupPosition).size();
    } */

    @Override
    public int getChildType(int groupPosition, int childPosition)
    {
        int result = 0;
        if (childPosition == getChildrenCount(groupPosition) - 1)
            result = 1;

        return result;
    }

    @Override
    public View getChildView (
            int groupPosition, int childPosition, 
            boolean isLastChild, 
            View convertView, ViewGroup parent)
    {
        if (convertView == null) {
            TextView textView = 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);
                    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));
                    break;
                case 1:
                    convertView = inflater.inflate(com.oleg.mart.foreign.R.layout.child_row, null);
                    textView = (TextView)convertView.findViewById(com.oleg.mart.foreign.R.id.Child);
                    textView.setPadding(30,20,30,20);
                    textView.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 15);
                    textView.setText(Html.fromHtml(myText));
                    break;
            }
        }
        return convertView;
    }
};

Wie Sie sehen, versuche ich, dem letzten untergeordneten Element einen anderen Stil zuzuweisen. Was könnte falsch sein?

RechtgetChildView Methode:

TextView textView = null;
String myText = null;
myText = childData.get(groupPosition).get(childPosition).get("chapter");

if (convertView == null) {
    LayoutInflater inflater = (LayoutInflater)getSystemService(getBaseContext().LAYOUT_INFLATER_SERVICE);
    int itemType = getChildType(groupPosition,childPosition);


    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));

return convertView;
