Activity closes when selecting listview item

I have an order app, I can load all the order products, since the setOnClickListener of listview did not work, put a setOnClick listener in the view of the adapter, but when I show a alerdialog it closes me the activity, I click on an item in the listview it shows me the alerdialog, when I want to click on another item it closes.

I put the code for my Adapter.

    public class ProductosPedidoAdapter extends CursorAdapter{
    TextView codigo, descripcion,cantidad,promocion;
    AlertDialog.Builder builder;
    public ProductosPedidoAdapter(Context context, Cursor c) {
        super(context, c, 0);
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(context);
        return inflater.inflate(R.layout.item_producto_pedido, parent, false);
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        try{
            builder = new AlertDialog.Builder(context);
            final TextView textomostrar = new TextView(context);
            codigo=(TextView) view.findViewById(R.id.text_productoCodigo_ped);
            descripcion=(TextView) view.findViewById(R.id.text_descripcion_ped);
            cantidad=(TextView) view.findViewById(R.id.text_cantidad_ped);
            promocion=(TextView)view.findViewById((R.id.text_promocion_ped));
            String codproducto=cursor.getString(cursor.getColumnIndex(contracts.detallePedido.DPcodproducto));
            codigo.setText(codproducto);
            descripcion.setText(cursor.getString(cursor.getColumnIndex(contracts.detallePedido.DPcodproducto)));
            cantidad.setText(cursor.getString(cursor.getColumnIndex(contracts.detallePedido.DPcantidad)));
            promocion.setText(cursor.getString(cursor.getColumnIndex(contracts.detallePedido.DPpromocion)));
            textomostrar.setText("Que desea realizar con el producto: "+codproducto);
            builder.setView(textomostrar).setTitle("Acciones");
            builder.setPositiveButton("Eliminar", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                }
            });
            builder.setNeutralButton("Actualizar", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            });
            builder.setNegativeButton("Cancelar", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {

                }
            });
            view.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    builder.show();
                }
            });
        }catch (Exception e){
            Log.e("adapterpropedidos", "bindView: ",e );
        }

    }
}

The catch does not catch anything.

UPDATE
