Hello, Kumar!
I have a problem when I try to add items to my custom adapter.
Everytime when i add new item to adapter
for(int i=0;i<m_orders.size();i++)
m_adapter.add(m_orders.get(i));
the size of m_orders (ArrayList joined to ListAdapter) also increase
and application hangs.
For example, i add to m_oders 20 items i need to display, than i must
add this items to adapter. Everytime when I add new item to adapter,
size of m_orders becomes 21, 22, 23, ... I don't understand why.
If i don't add items to adapter, i have empty listview.
I hope i explain my problem :)
Much appreciate for your time, Kumar :)))
