在這裏，這是我的java文件

public class Create_Event extends SherlockFragment implements OnClickListener { 

Button b_start_calender, b_end_calender, b_start_timepicker, b_end_timepicker; 
EditText start_date, start_time, end_date, end_time; 
private int start_year, start_month, start_day, start_hour, start_minute; 
private int end_year, end_month, end_day, end_hour, end_minute; 

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 

b_start_calender=(Button)rootView.findViewById(R.id.btn_start_calender); 
    b_start_timepicker=(Button)rootView.findViewById(R.id.btn_start_timepicker); 
    b_end_calender=(Button)rootView.findViewById(R.id.btn_end_calender);

    start_date=(EditText)rootView.findViewById(R.id.start_date); 
    start_time=(EditText)rootView.findViewById(R.id.start_time); 
    end_date=(EditText)rootView.findViewById(R.id.end_date); 
    end_time=(EditText)rootView.findViewById(R.id.end_time); 

    b_start_calender.setOnClickListener(this); 
    b_start_timepicker.setOnClickListener(this); 
    b_end_calender.setOnClickListener(this); 
    b_end_timepicker.setOnClickListener(this); 

return rootView;   
} 


@Override 
public void onClick(View v) { 
    // TODO Auto-generated method stub 


if(v==b_start_calender) { 
    final Calendar c=Calendar.getInstance(); 
    start_year=c.get(Calendar.YEAR);

      startDate.set(Calendar.MONTH, monthOfYear); 
      startDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 
      start_date.setText(dayOfMonth + "-" 
        + (monthOfYear + 1) + "-" + year); 
     } 
    }; 
    DatePickerDialog d = new DatePickerDialog(getActivity(),

    d.show(); 
} 

if(v==b_start_timepicker) { 
    final Calendar c = Calendar.getInstance(); 
    start_hour=c.get(Calendar.HOUR_OF_DAY); 
    start_minute=c.get(Calendar.MINUTE); 

    TimePickerDialog.OnTimeSetListener mTimeSetListner = new TimePickerDialog.OnTimeSetListener() { 

     @Override 
     public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
      start_time.setText(hourOfDay + ":" + minute); 
     } 
    }; 
    TimePickerDialog t=new TimePickerDialog(getActivity(), mTimeSetListner, start_hour, start_minute,false); 
    t.show(); 
} 

if(v==b_end_calender) { 
    final Calendar c=Calendar.getInstance(); 
    end_year=c.get(Calendar.YEAR); 
    end_month=c.get(Calendar.MONTH); 
    end_day=c.get(Calendar.DAY_OF_MONTH); 

    DatePickerDialog.OnDateSetListener mDateSetListener = new DatePickerDialog.OnDateSetListener() { 
     public void onDateSet(DatePicker view, int year, 
       int monthOfYear, int dayOfMonth) {

      newEndDate.set(Calendar.YEAR, year); 
      newEndDate.set(Calendar.MONTH, monthOfYear); 
      newEndDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 



      if(newEndDate.before(startDate)) 
      { 
       end_date.setText("Plz.. enter date after starting date.."); 

      } 

      else 
      { 

       end_date.setText(dayOfMonth + "-" 
         + (monthOfYear + 1) + "-" + year); 

      } 


     } 
    }; 
    DatePickerDialog d = new DatePickerDialog(getActivity(), 
      mDateSetListener, end_year, end_month, end_day); 
    d.show();  
} 


if(v==b_end_timepicker) { 
    final Calendar c = Calendar.getInstance(); 
    end_hour=c.get(Calendar.HOUR_OF_DAY); 
    end_minute=c.get(Calendar.MINUTE); 

    TimePickerDialog.OnTimeSetListener mTimeSetListner = new TimePickerDialog.OnTimeSetListener() { 

     @Override 
     public void onTimeSet(TimePicker view, int hourOfDay, int minute) { 
      end_time.setText(hourOfDay + ":" + minute); 
     } 
    }; 
    TimePickerDialog t=new TimePickerDialog(getActivity(), mTimeSetListner, end_hour, end_minute,false); 
    t.show(); 
} 
}

這裏，開始日期和結束日期正確設置。結束日期不能在開始日期之前設置。但是，如果我們先設置結束日期，然後再開始日期...在這種情況下，它不能正常工作。如何處理這種情況？我也需要那個開始和結束日期不能相同，並且用戶不能在今天的日期之前選擇日期...在哪裏放條件？我怎樣才能做到這一點？？請幫助...

我會將您的結束日期監聽器更改爲以下內容。

if(v==b_end_calender) { 
    final Calendar c=Calendar.getInstance(); 
    end_year=c.get(Calendar.YEAR); 
    end_month=c.get(Calendar.MONTH); 
    end_day=c.get(Calendar.DAY_OF_MONTH); 

    DatePickerDialog.OnDateSetListener mDateSetListener 
     = new DatePickerDialog.OnDateSetListener() { 
      public void onDateSet(DatePicker view, 
       int year, int monthOfYear, int dayOfMonth) { 
       Calendar newEndDate = Calendar.getInstance(); 
       newEndDate.set(Calendar.YEAR, year); 
       newEndDate.set(Calendar.MONTH, monthOfYear); 
       newEndDate.set(Calendar.DAY_OF_MONTH, dayOfMonth); 

       if(newEndDate.before(startDate)) { 
        // handle the error 
       } else { 
       end_date.setText(dayOfMonth + "-" + (monthOfYear + 1) + "-" + year); 
       } 

      } 
    }; 

    new DatePickerDialog(getActivity(), 
     mDateSetListener, end_year, end_month, end_day).show();

}

如果你注意到，我使用了一個全局變量startDate。選中時，您將需要將其全局存儲。其次，查看DateFormatter類，我相信它們對你來說是有用的。

乾杯。

您也可以使用endDate全局變量，因爲您可能想要防止startDate在endDate之後。 – tambykojak

是的，它工作....非常感謝您分享您的知識....其實我沒有宣佈startDate作爲全局變量...這就是爲什麼它不工作... – user3388240
