Activity enters onPause only the first time it is called

Question

I’ve got a Pedidocad Activity calling a Productocons, following code to open Productocons:

Intent intent = new Intent(PedidoCadActivity.this, ProdutoConsActivity.class);
 intent.putExtra("activity", "pedidoCad");
 startActivityForResult(intent, 2);

When I choose the item I want in Activity Productocons, I click on the button that executes this code:

setTotalItem();
setObjPedidoItens();
setDescPorcentagem();
setDescValor();
Bundle bundle = new Bundle();
bundle.putParcelable("objPedidoItem", objPedidoItem);
Intent i = new Intent();
i.putExtras(bundle);
setResult(1, i);
finish();

The problem is that when finishing Productocons for the second time to add the second product, it does not fall into onResume, it goes to onCreate, and the Listview that is added the items is restarted every time do not know why.
