我有一个日期选择器对话框，如果我将 MAX date 和 Min date 一起设置，则应用程序崩溃。而如果我只设置最小日期或最大日期它工作正常.. 帮助我找出我哪里出错了。

   private void setDate(View c_c) {
    // TODO Auto-generated method stub

    final Dialog dialog = new Dialog(getParent());
    dialog.setContentView(R.layout.date_picker);
    dialog.setTitle("Select Date");
    DatePicker calendarView = (DatePicker) dialog.findViewById(R.id.date_picker_datepicker);

    try {
        Log.d("***ENC_dATE****",Utility.getCurrentDate()+"*******"+Utility.convertStringToMilli(Utility.getCurrentDate()));
        calendarView.setMinDate(Utility.convertStringToMilli(Utility.convertStringFormat(CommonObjects.patientsDtoEncounter.getEpisodeDate())));
        calendarView.setMaxDate(Utility.convertStringToMilli(Utility.getCurrentDate()));
    } catch (Exception e) {
        e.printStackTrace();
    }
    Button button = (Button) dialog.findViewById(R.id.btn_cancel_datepicker);

    button.setOnClickListener(new OnClickListener() {

        public void onClick(View v) {

            dialog.dismiss();
        }


    });

    button = (Button) dialog.findViewById(R.id.btn_set_datepicker);
    button.setTag(c_c);

    // if button is clicked, close the custom dialog
    button.setOnClickListener(new OnClickListener() {
        public void onClick(View v) {

            dialog.dismiss();
        }
    });

    dialog.show();

}

这是我的日志。

我和你有同样的问题。在我的应用程序中，我有一个扩展 DatePickerDialog 并在单击按钮时显示它的片段。该应用程序在有足够空间显示日期选择器的日历视图的较大屏幕上崩溃。但是，对于我的应用程序，不需要日历视图，并且通过禁用它，应用程序在设置最小和最大日期时不再崩溃。

因此，如果您的应用程序也是这种情况，您不需要日历视图，请尝试通过在日期选择器实例上调用 setCalendarViewShown(false) 来禁用它。
