Question

我在我的GWT中创建了多个动态的无线电按钮

      public void createTestList(ArrayList<Test> result){
    for(int i =0 ; i<result.size();i++){
                    int id = result.get(i).getTestId();
        RadioButton rd = new RadioButton("group", result.get(i).getTestType());
        verticalPanel.add(rd);
    }

测试是我的实体类...

现在,如果我选择一个无线电按钮, 首先我需要获得所选无线电按钮的代号, 这怎么可能?

第二,我如何检查选择哪个多个无线电按钮?

谢谢谢谢

Answer 1

您需要检查 public java. lang. Boolean getValue () 的每个收音机按钮是否被检查。

Answer 2

可能添加点击处理器并更新选中的 radio 按钮变量 :

choiceItemKind = new VerticalPanel();
ArrayList<String> kinds = new ArrayList<String>();
kinds.add(...);
kinds.add(...);

choiceItemKind.clear();

ClickHandler choiceClickHandler = new ClickHandler()
{
    @Override
    public void onClick(ClickEvent event)
    {
        addItemKindSelectedLabel = ((RadioButton) event.getSource()).getText();
    }
};

for (String label : kinds)
{
    RadioButton radioButton = new RadioButton("kind", label);
    //radioButton.setTitle("Tooltyp");
    if (label.equals(addItemKindSelectedLabel))
        radioButton.setValue(true);
    radioButton.addClickHandler(choiceClickHandler);
    choiceItemKind.add(radioButton);
}
...
addItemKindSelectedLabel = "";
...
if (!addItemKindSelectedLabel.isEmpty())
    ...;

d: 设置选定的无线按钮, 不重建 :

for (int i = 0; i < choiceItemKind.getWidgetCount(); i++)
{
    RadioButton radioButton = (RadioButton) choiceItemKind.getWidget(i);
    radioButton.setValue(radioButton.getText().equals(addItemKindSelectedLabel));
}
