Question

我正在从ArrayList创建一个Multibutton，涉及两个键。 “id”和“code”。我只想在UI上显示“代码”并隐藏“id”，因为我只需要actionListener的“id”。

我的方法，开放进行更正

我只想显示TextLine1 [“code”]并隐藏TextLine2 [“id”]

for(int x= 0; x < policies2.size(); x++)
{
  final MultiButton mb = new MultiButton();   
  Double policy_id = (Double)policies2.get(x).get("id");
  mb.setTextLine1((String) policies2.get(x).get("code"));
  mb.setTextLine2(policies2.get(x).get("policy_id")+""); //how can i hide this/bind it to the Multi withou showing it on the UI.
  mb.addActionListener(new ActionListener(){
   //use "id" here
   //mb.getTextLine2()
 }
}

如何使用“id”而不在UI上显示

Answer 1

实际上这很简单。我刚刚将addActionListener内部类的id声明为final，我没有必要将它设置为TextLine2。

final Double db = (Double)policies2.get(x).get("policy_id");
mb.addActionListener(new ActionListener(){
  System.out.println(db);
}

Answer 2

试试这个：

final MultiButton mb = new MultiButton();   
  final Double policy_id = (Double)policies2.get(x).get("id");
  mb.setTextLine1((String) policies2.get(x).get("code"));
  //mb.setTextLine2(policies2.get(x).get("policy_id")+""); //how can i hide this/bind it to the Multi withou showing it on the UI.
  mb.addActionListener(new ActionListener(){
   public void actiobPerformed(ActionEvent e){
      double id = policy_id.doubleValue();
      ...
    }
   }
 }
