schoolYear = (Button) findComponentById(ResourceTable.Id_school_year);
schoolYear.setClickedListener(component -> {
     
    ListDialog listDialog = new ListDialog(this);
    String []items = {
     "2024-2025", "2023-2024", "2022-2023", "2021-2022", "2020-2021",
            "2019-2020", "2018-2019"};
    listDialog.setItems(items);
    listDialog.setTitleText("请选择学年:");
    listDialog.setAlignment(LayoutAlignment.CENTER);
    listDialog.setOnSingleSelectListener((iDialog, i) -> {
     
        schoolYear.setText(items[i]);
        listDialog.destroy();
    });
    listDialog.show();
});
