將容器添加到代號爲1的特定滑動選項卡？

Question

如何根據選項卡的索引值動態地將容器添加到特定的滑動選項卡？

Answer 1

容器可以添加到標籤，如下所示。

 tabs.addSelectionListener(new SelectionListener() { 

      @Override 
      public void selectionChanged(int oldSelected, int newSelected) { 


addComponent(newSelected) 

       } 
       } 

       void addContainer(int index){ 
       Container container = new Container(); 
    tabs.addComponent(index, container); 


     } 

Answer 2

void addComponent(int newSelected,NamesListBean nameListBean) { 
      displayContainer = new Container(new BoxLayout(BoxLayout.Y_AXIS)); 
      displayContainer.removeAll(); 
      for(NamesBeans names:nameListBean.getNamesList()){ 
       displayContainer.setLayout(new BoxLayout(BoxLayout.Y_AXIS)); 
       Label name=new Label(names.getNames()); 
       Log.p("names======="+names.getNames()); 
       //displayNamesContainer.removeAll(); 

       //displayNamesContainer.forceRevalidate(); 
       displayContainer.add(name); 
      } 
      //getDisplay(displayContainer); 
      //Container container = new Container(); 
      tabs.addComponent(newSelected, displayContainer); 
      displayContainer.revalidate(); 
     } 
    });

下面是一個簡單的例子，當按下按鈕，增加了一個標籤到當前選擇的選項卡：

    int compIndex = 1; 
    public void start() { 
     if(current != null){ 
      current.show(); 
      return; 
     } 
     Form hi = new Form("Hi World", new BorderLayout()); 

     Tabs tabs = new Tabs(); 
     tabs.addTab("Tab 1", BoxLayout.encloseY(new Label("Tab 1"))); 
     tabs.addTab("Tab 2", BoxLayout.encloseY(new Label("Tab 2"))); 
     tabs.addTab("Tab 3", BoxLayout.encloseY(new Label("Tab 3"))); 

     Button btn = new Button("Add To current"); 

     btn.addActionListener(e->{ 
      ((Container)tabs.getSelectedComponent()).add("Added Component "+(compIndex++)) 
        .revalidate(); 
     }); 


     hi.add(BorderLayout.CENTER, tabs).add(BorderLayout.SOUTH, btn); 
     hi.show(); 
    }
