Hello I hope you are able to understand me, my English is not good, sorry
, I have an activity
that contains a listview
of products,if you click is added to another activity shopping cart. So far so good. I have gotten that if you click 2 times an article, 2 same items will not be added in the shopping cart, but now I want to establish a method to show me the same item if I pressed 2 times, exit 2 in the quantity field , and the price multiply by two, logically.
So insert the clicked item in the cart activity:
I created a variable that counts how many times an item was clicked,(contador)
case 0:
if (page1 == null)
{
page1 = (ListView) LayoutInflater.from(Local_mostrar_bebidaActivity.this).inflate(R.layout.page_one_viewpager_listview, null);
page1.setAdapter(adapterlistvMenuBEBIDAS);
page1.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
ItemListView item = itemsListVMenuBEBIDAS.get(position);
if (MiPedidoActivity.itemsListVMiPedido.contains(item)) { // <- look for item!
// ... item already in list
Log.i(LOGTAG, "Añadido item "+ contador+" "+ numUds);
++contador;
numUds=contador;
}
else {
MiPedidoActivity.itemsListVMiPedido.add(item);
contador= 1;
numUds=contador;
Log.i(LOGTAG, "Añadido item "+ contador+" "+ numUds);
}});
}
page = page1;
break;
I so add the products in the arraylist
private static ArrayList<ItemListView> obtenerItemsMenuBEBIDAS() {
ArrayList<ItemListView> itemsMenuBEBIDAS = new ArrayList<ItemListView>();
itemsMenuBEBIDAS.add(new ItemListView(1, "Product1", "malta y z.", "drawable/a1","3.10",""+numUds));
itemsMenuBEBIDAS.add(new ItemListView(3, "Cocacola", "Botellin de 22ml","drawable/cocacola_logo","1.75",""+ numUds));
itemsMenuBEBIDAS.add(new ItemListView(4, "Cocacola Zero", "Botellin de 22ml","drawable/cocacola_zero","1.75",""+ numUds ));
return itemsMenuBEBIDAS;
}
(numUds) is a variable that I have created to know how many units have been clicked and then display the corresponding textview
Any idea?
