如何将微调器值从片段传递给任何帮助器类

通过文本

String text = spinner.getSelectedItem().toString();
至此处的值

public FirebaseDatabaseHelper() {
    Calendar instance = Calendar.getInstance(TimeZone.getDefault());
    SimpleDateFormat month_date = new SimpleDateFormat("MMMM");
    final String month_name = month_date.format(instance.getTime());
    final String currentYear = String.format("%02d", instance.get(Calendar.YEAR));


    mDatabase = FirebaseDatabase.getInstance();
    mReferenceTujuan = mDatabase.getReference(valueHere);
}
调用从用户处获取微调器值的函数后，需要按语法将其设置为默认值或案例中的第一个值

yourspinner.setSelection（第一项）

在从用户获取微调器数据以重置微调器的函数中执行此操作
