android - 日期选择器对话。当我设置最大和最小日期时应用程序崩溃

标签 android date datepicker

我有一个日期选择器对话框，如果我同时设置最大日期和最小日期，应用程序会崩溃。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。

最佳答案

我遇到了和你一样的问题。在我的应用程序中，我有一个 fragment 可以扩展 DatePickerDialog 并在单击按钮时显示它。该应用程序在有足够空间显示日期选择器的日历 View 的大屏幕上崩溃。然而，对于我的应用程序，不需要日历 View ，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，如果您的应用也需要日历 View ，请尝试通过在日期选择器实例上调用 setCalendarViewShown(false) 来禁用它。

关于android - 日期选择器对话。当我设置最大和最小日期时应用程序崩溃，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/18437702/
