dialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);

这是正常的,日期选择器中的过去日期看起来是禁用的.但是我仍然可以点击上一个日期并选择它.
怎么不让这种情况发生？
下面是我的日期选择器的截图：

这里是我的代码,我禁用过去的日期：

@Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {
        // Use the current date as the default date in the picker
        final Calendar c = Calendar.getInstance();
        int year = c.get(Calendar.YEAR);
        int month = c.get(Calendar.MONTH);
        int day = c.get(Calendar.DAY_OF_MONTH);
        mActivity = new WeakReference<CreateEvent>(
                (CreateEvent) getActivity());

        DatePickerDialog dialog = new DatePickerDialog(getActivity(),this,year,month,day);

        if(callingView==fromDate){
            dialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000);
        }else if (callingView==toDate){
            dialog.getDatePicker().setMinDate(fromD);
        }

        // Create a new instance of DatePickerDialog and return it
        return dialog;
    }
