我正在使用此代码显示警告对话框…当我点击确定按钮时,它应显示日期选择器..
- protected Dialog onCreateDialog(int id) {
- switch (id) {
- case TIME_DIALOG_ID:
- return new TimePickerDialog(ListReminderActivity.this,mTimeSetListener,mHour,mMinute,false);
- case DATE_DIALOG_ID:
- return new DatePickerDialog(ListReminderActivity.this,mDateSetListener,mYear,mMonth,mDay);
- case DESCRIPTION_DIALOG_ID:
- return new AlertDialog.Builder(ListReminderActivity.this).setTitle(
- "Add Reminder").setView(description).setPositiveButton(
- R.string.add_alert_ok,new DialogInterface.OnClickListener() {
- public void onClick(DialogInterface dialog,int whichButton) {
- ListReminderActivity.this
- .dismissDialog(DESCRIPTION_DIALOG_ID);
- ListReminderActivity.this
- .removeDialog(DESCRIPTION_DIALOG_ID);
- ListReminderActivity.this
- .showDialog(DATE_DIALOG_ID);
- }
- }).setNegativeButton(R.string.add_alert_cancel,int whichButton) {
- ListReminderActivity.this
- .dismissDialog(DESCRIPTION_DIALOG_ID);
- ListReminderActivity.this
- .removeDialog(DESCRIPTION_DIALOG_ID);
- }
- }).create();
- }
- return null;
- }
但问题是..当我按下确定按钮时,我得到了例外
例外是……
