Android 如何打印小时和分钟的零，这些零是个位数？

当我想在editText中打印时，可能是由于对话框中的时差，它比我当前的时间晚了3个小时。我无法在所选小时或分钟的左边打印零

end_time_time.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

        final Calendar myCalender = Calendar.getInstance();
        int hour = myCalender.get(Calendar.HOUR_OF_DAY);
        int minute = myCalender.get(Calendar.MINUTE);

        TimePickerDialog.OnTimeSetListener myTimeListener = new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
                if (view.isShown()) {
                    myCalender.set(Calendar.HOUR_OF_DAY, hourOfDay);
                    myCalender.set(Calendar.MINUTE, minute);
                    end_time.setText( hourOfDay + ":" + minute);
                }
            }
        };
        TimePickerDialog timePickerDialog = new TimePickerDialog(Event.this, android.R.style.Theme_Holo_Light_Dialog_NoActionBar, myTimeListener, hour, minute, true);
        timePickerDialog.setTitle(R.string.time_select);
        timePickerDialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
        timePickerDialog.show();
    }
});

简单的字符串操作如何：

String sMinute = String.valueOf(minute);
if(minute < 10) sMinute = "0" + sMinute;
String sHourOfDay = String.valueOf(hourOfDay);
if(hourOfDay < 10) sHourOfDay = "0" + sHourOfDay;
end_time.setText( sHourOfDay + ":" + sMinute);

String sMinute=String.valueOf（分钟）；
如果（分钟<10）sMinute=“0”+sMinute；
String sHourOfDay=String.valueOf（hourOfDay）；
如果（hourOfDay<10）sHourOfDay=“0”+sHourOfDay；
结束时间.setText（sHourOfDay+“：”+sMinute）；

这对我很有效。我已经试了好几个小时了。谢谢这对我很有用。我已经试了好几个小时了。谢谢
