datepicterDialog和timepicterDialog取消按钮

这是日期弹出框的第一种弹出方式：分开弹出datepicterdialog和timepicterdialog

final DatePickerDialog datePickerDialog = new DatePickerDialog(
       TableChart.this, null, mYear, mMonth,
       mDay);
     datePickerDialog.setButton(DialogInterface.BUTTON_POSITIVE,
       "完成", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface arg0,
          int arg1) {
         DateTimeUtils.showDatePositive(datePickerDialog,starttime);
        }
       });
     datePickerDialog.setButton(DialogInterface.BUTTON_NEGATIVE,
       "取消", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface arg0,
          int arg1) {
         DateTimeUtils.showDateNegative(starttime);
        }
       });
     datePickerDialog.setCanceledOnTouchOutside(false);
     datePickerDialog.show();
 
public static void showDatePositive(DatePickerDialog datePickerDialog,
   EditText yearEdit) {
  DatePicker datePicker = datePickerDialog.getDatePicker();//获取DatePicter对象
  int year = datePicker.getYear();
  int month = datePicker.getMonth() + 1;
  int day = datePicker.getDayOfMonth();
  yearEdit.setText(year+"-"month+"-"+day);
  yearEdit.clearFocus();
  }
public static void showDateNegative(EditText yearEdit) {
  yearEdit.clearFocus();
  }
由于timepicterDialog无法获取到timepicter,所以重写：MyTimePickerDialog.java

使用方法：
final MyTimePickerDialog timePickerDialog = new MyTimePickerDialog(
         TableSlideZaiHaiActivity.this, null,
         mhour, mmintue, true);
       timePickerDialog.setButton(DialogInterface.BUTTON_POSITIVE,
         "完成", new DialogInterface.OnClickListener() {
          @Override
          public void onClick(DialogInterface arg0,
            int arg1) {

          }
         });
       timePickerDialog.setButton(DialogInterface.BUTTON_NEGATIVE,
         "取消", new DialogInterface.OnClickListener() {
          @Override
          public void onClick(DialogInterface arg0,
            int arg1) {
           DateTimeUtils.showTimeNegative(slidedown_huadongtimehour);
          }
         });
       timePickerDialog.setCanceledOnTouchOutside(false);
       timePickerDialog.show();
      
       public static void showTimePositive(MyTimePickerDialog timePickerDialog,EditText hourEdit) {
  TimePicker timePicker = timePickerDialog.getTimePicker();
  int hour = timePicker.getCurrentHour();
  int mintue = timePicker.getCurrentMinute();
  hourEdit.setText(hour+":"+mintue);
   hourEdit.clearFocus();
   }
public static void showTimeNegative(EditText hourEdit, EditText ) {
  hourEdit.clearFocus();
   }
