Question

嘿人？我在J2ME平台上使用LWUIT从两个RadionButtons（男性和女性）中获取所选项目时遇到了挑战。

RadioButton selected = genderGroup.getRadioButton(genderGroup.getSelectedIndex());
String selectedGender = selected.toString();

我尝试了上面的代码块，但从未达到我的预期。

有人请帮我一把。

此致凯文。

Answer 1

我想您要从RadioButton中提取的内容是与此RadioButton相关联的文字。为此，您需要使用getText()代替toString()。

这就是你想要做的吗？

hey kevintich请使用本准则......

ComponentGroup radioGroup = new ComponentGroup();
final RadioButton defaultBorder = new RadioButton("Default");
radioGroup.addComponent(defaultBorder);
final RadioButton etchedBorder = new RadioButton("Etched Raised Theme");
radioGroup.addComponent(etchedBorder);
final RadioButton etchedColors = new RadioButton("Etched Raised Colors");
radioGroup.addComponent(etchedColors);
final RadioButton etchedLowBorder = new RadioButton("Etched Lowered Theme");
radioGroup.addComponent(etchedLowBorder);
final RadioButton etchedLowColors = new RadioButton("Etched Lowered Colors");
radioGroup.addComponent(etchedLowColors);
final RadioButton bevelBorder = new RadioButton("Bevel Raised Theme");
radioGroup.addComponent(bevelBorder);
final RadioButton bevelColors = new RadioButton("Bevel Raised Colors");
radioGroup.addComponent(bevelColors);
final RadioButton bevelLowBorder = new RadioButton("Bevel Lowered Theme");
radioGroup.addComponent(bevelLowBorder);
final RadioButton bevelLowColors = new RadioButton("Bevel Lowered Colors");
radioGroup.addComponent(bevelLowColors);
final RadioButton roundBorder = new RadioButton("Round Theme");
radioGroup.addComponent(roundBorder);
final RadioButton roundColors = new RadioButton("Round Colors");
radioGroup.addComponent(roundColors);
RadioButton disabledRadioButton = new RadioButton("Disabled Radio Button");
disabledRadioButton.setEnabled(false);
radioGroup.addComponent(disabledRadioButton);
f.addComponent(radioGroup);
