Question

如何根据动态选项卡的选定索引值将容器添加到特定的滑动选项卡？

Answer 1

这是一个简单的例子，当按下按钮时，它会向当前选中的标签添加标签：


    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();
    }

Answer 2

可以将容器添加到标签中，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 3

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();
        }
    });
