bom dia a todos, tenho uma tela de vendas (veja imagem anexa), nesta tela seleciono um produto para vender (ComboBox) e ao selecionar o produto o campo Valor Unitário é preenchido automaticamente pelo valor salvo no MySQL.
Preciso de ajuda para formatar esse valor, forma correta:
1.000,00
O valor está retornando com este formato:
1000,0 = ou seja, o ponto está faltando e uma casa decimal está faltando
Como resolver esse problema?
código usado para formatação:
List<Produto> listaDeProdutos = produtoRepository.findAll();
txtProdutos.setItemLabelGenerator(Produto::getNome);
txtProdutos.setItems(listaDeProdutos);
txtProdutos.addValueChangeListener(event -> {
NumberFormat formatter = NumberFormat.getNumberInstance(Locale.US);
try {
Number number = formatter.parse(event.getValue().getValor().toString());
txtValorUnitario.setPrefixComponent(new Label("R$"));
txtValorUnitario.setValue(BigDecimal.valueOf(number.doubleValue()));
} catch (Exception e) {
// TODO: handle exception
e.printStackTrace();
}
});
Tente pegar a NumberFormat assim:
NumberFormat.getCurrencyInstance(new Locale(“pt”, “BR”));

da este erro ao tentar a solução que você passou
Troque esse código:
Number number = formatter.parse(event.getValue().getValor().toString());
txtValorUnitario.setPrefixComponent(new Label("R$"));
txtValorUnitario.setValue(BigDecimal.valueOf(number.doubleValue()));
Por esse:
txtValorUnitario.setPrefixComponent(new Label("R$"));
txtValorUnitario.setValue(formatter.format(event.getValue().getValor());

Consegui resolver o problema…com este ultimo codigo que vc mandou eu precisava trocar o tipo de campo
ANTES:
BigDecimalField txtValorUnitario = new BigDecimalField(“Valor Unitário”);
ATUAL:
Textfield txtValorUnitario = new Textfield(“Valor Unitário”);
muito obrigado…gratidão!!
