我在我的 Android 应用程序中做了以下两件事。首先，在单击编辑文本时，我打开了一个 Datepicker。我单击一个日期，日期以 2014 年 12 月 5 日的格式设置在编辑文本上。我想将其设置为 2014 年 5 月 12 日这样的格式。这个怎么做。其次，在单击另一个编辑文本时，我打开一个 TimePicker，单击它会在编辑文本上以 1:30 的形式设置时间。我想将其设置为下午 1:30。这个怎么做？我在下面发布我的代码，请逐步指导我。

日期选择器代码

final DatePickerDialog.OnDateSetListener date = new DatePickerDialog.OnDateSetListener() {

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,
        int dayOfMonth) {
    // TODO Auto-generated method stub
     myCalendar.set(Calendar.YEAR, year);
        myCalendar.set(Calendar.MONTH, monthOfYear);
        myCalendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);
        updateLabel();
}

private void updateLabel() {
    // TODO Auto-generated method stub
    String myFormat = "MM/dd/yy"; //In which you need put here
    SimpleDateFormat sdf = new SimpleDateFormat(myFormat, Locale.US);

    datepick.setText(sdf.format(myCalendar.getTime()));
}

   };
 datepick.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
     new DatePickerDialog(getActivity(), date, myCalendar
             .get(Calendar.YEAR), myCalendar.get(Calendar.MONTH),
             myCalendar.get(Calendar.DAY_OF_MONTH)).show();
}
   } );

时间选择器代码

tasktime.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
    // TODO Auto-generated method stub
     Calendar mcurrentTime = Calendar.getInstance();
     int hour = mcurrentTime.get(Calendar.HOUR_OF_DAY);
     int minute = mcurrentTime.get(Calendar.MINUTE);

     TimePickerDialog mTimePicker;
     mTimePicker=new TimePickerDialog(getActivity(), new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub
             tasktime.setText( hourOfDay + ":" + minute);
        }
    }, hour, minute, true);
     mTimePicker.setTitle("Select Time");
     mTimePicker.show();
}
  });

将日期格式从 "MM/dd/yy" 更改为 "dd MMM,yyyy" 并及时使用 simpleDateFomate 格式为 "h:mm a"

使用SimpleDateFormat。使用下面的方法并以字符串格式提供您的日期作为参数

public static String dateFormatter(String date)

    {
        SimpleDateFormat sdf = new SimpleDateFormat("MM-dd-yyyy");

        String s = "";
        try {
            Date dt = sdf.parse(date);
            sdf = new SimpleDateFormat("dd-MMM-yyyy");
            s = sdf.format(dt);
            // Log.v("*****", s);

        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
        return s;
    }

对于时间，请参考以下链接： 使用 Android 将时间值转换为格式“hh:mm Am/Pm”

// try this way,hope this will help you....

@Override
public void onDateSet(DatePicker view, int year, int monthOfYear,int dayOfMonth) {
    Time chosenDate = new Time();
    chosenDate.set(dayOfMonth, monthOfYear, year);
    long dt = chosenDate.toMillis(true);
    CharSequence strDate = DateFormat.format(MM/dd/yy", dt);
    datepick.setText(strDate.toString());
}

@Override
public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
   Calendar date = Calendar.getInstance();
   Time chosenDate = new Time();
   chosenDate.set(0, minute, hourOfDay, date.get(Calendar.DAY_OF_MONTH), date.get(Calendar.MONTH), date.get(Calendar.YEAR));
   long dt = chosenDate.toMillis(true);
   CharSequence strDate = DateFormat.format("kk:mm", dt);
   tasktime.setText(strDate);
}
