Java 在组合框中选择ascendingorder时如何对元素列表进行排序

我创建了一个组合，其中包含包含字符串的列表。我有一个组合框，其中有升序和降序选项。现在，如果我在组合框中选择升序，列表应该按字母顺序排序。那么如何做到这一点呢

例如，如果我的合成包含一个列表“some”、“zero”、“one” 然后在我的组合框中选择升序，它应该被排序并显示为一，一些，零

创建combobox的代码如下

String[] ITEMS1 = {"A-Z",  "Z-A"  };
comboSort = new Combo(comboComposite, SWT.NONE);
        comboSort.setBounds(84, 2, 91, 23);
        comboSort.setItems(ITEMS1);


        tabFolder = new TabFolder(topComposite, SWT.NONE);
        GridData tabFolderGD = new GridData(SWT.FILL, GridData.FILL, true, true);
        tabFolderGD.verticalIndent = 4;
        tabFolderGD.horizontalSpan = 2;
        tabFolder.setLayoutData(tabFolderGD);

        TabItem tabItem = new TabItem(tabFolder, SWT.NONE);
        tabItem.setText("My created");
        createListViewMycreated(tabFolder,tabItem);

private void createListViewMycreated(Composite composite, TabItem ItemMycreated){
        List myCreatedList = new List(composite,SWT.BORDER);
        myCreatedList.setItems(new String[]{"CompSetup_SEMCW8459_TiffanyA005    ","Product_Sirius_Perch_OEM0_AID1_00440245156645    ","SW_SEC Test_DEMO_Sirius   "});
        ItemMycreated.setControl(myCreatedList);
        setDragSource(myCreatedList);

        comboSort.addSelectionListener(new SelectionListener() {

            @Override
            public void widgetDefaultSelected(SelectionEvent e) {
                // TODO Auto-generated method stub
                 System.out.println("hi you selected me in combo box"+comboSort.getText());
            }

            @Override
            public void widgetSelected(SelectionEvent e) {
                // TODO Auto-generated method stub
                System.out.println("hi you selected me in combo box"+comboSort.getText());
                String ascending =comboSort.getText();
                if (ascending== "A-Z")
                {

                }
            }


            });

    }

tabitem和监听器的代码如下

String[] ITEMS1 = {"A-Z",  "Z-A"  };
comboSort = new Combo(comboComposite, SWT.NONE);
        comboSort.setBounds(84, 2, 91, 23);
        comboSort.setItems(ITEMS1);


        tabFolder = new TabFolder(topComposite, SWT.NONE);
        GridData tabFolderGD = new GridData(SWT.FILL, GridData.FILL, true, true);
        tabFolderGD.verticalIndent = 4;
        tabFolderGD.horizontalSpan = 2;
        tabFolder.setLayoutData(tabFolderGD);

        TabItem tabItem = new TabItem(tabFolder, SWT.NONE);
        tabItem.setText("My created");
        createListViewMycreated(tabFolder,tabItem);

private void createListViewMycreated(Composite composite, TabItem ItemMycreated){
        List myCreatedList = new List(composite,SWT.BORDER);
        myCreatedList.setItems(new String[]{"CompSetup_SEMCW8459_TiffanyA005    ","Product_Sirius_Perch_OEM0_AID1_00440245156645    ","SW_SEC Test_DEMO_Sirius   "});
        ItemMycreated.setControl(myCreatedList);
        setDragSource(myCreatedList);

        comboSort.addSelectionListener(new SelectionListener() {

            @Override
            public void widgetDefaultSelected(SelectionEvent e) {
                // TODO Auto-generated method stub
                 System.out.println("hi you selected me in combo box"+comboSort.getText());
            }

            @Override
            public void widgetSelected(SelectionEvent e) {
                // TODO Auto-generated method stub
                System.out.println("hi you selected me in combo box"+comboSort.getText());
                String ascending =comboSort.getText();
                if (ascending== "A-Z")
                {

                }
            }


            });

    }

那么现在我们如何根据组合框选择对列表进行排序呢？我认为myCreatedList有一个字符串列表

Collections.sort(myCreatedList);

如果它在下降，那么

Collections.reverse(myCreatedList);

有关收藏的更多信息

这可能会起到以下作用：

      // Re-sort
      String[] items = combo.getItems();
      Arrays.sort(items);
      combo.setItems(items);

@SrikanthBadida哦，好吧，我以为你只需要分类的东西。请勾选这个，这可能有助于你编写代码
