android 到计时器,android倒计时器时间

我一直在使用

android倒计时器样本来创建某个日期的倒计时.

Time TimerSet = new Time();

TimerSet.set(20,8,2012); //day month year

TimerSet.normalize(true);

long millis = TimerSet.toMillis(true);

Time TimeNow = new Time();

TimeNow.setToNow(); // set the date to Current Time

TimeNow.normalize(true);

long millis2 = TimeNow.toMillis(true);

long millisset = millis - millis2; //subtract current from future to set the time remaining

final int smillis = (int) (millis); //convert long to integer to display conversion results

final int smillis2 = (int) (millis2);

new CountDownTimer(millisset,1000) {

public void onTick(long millisUntilFinished) {

// decompose difference into days,hours,minutes and seconds

int weeks = (int) ((millisUntilFinished / 1000) /

604800);

int days = (int) ((millisUntilFinished / 1000) / 86400);

int hours = (int) (((millisUntilFinished / 1000) - (days

* 86400)) / 3600);

int minutes = (int) (((millisUntilFinished / 1000) - ((days

* 86400) + (hours * 3600))) / 60);

int seconds = (int) ((millisUntilFinished / 1000) % 60);

int millicn = (int) (millisUntilFinished / 1000);

w.setText(" " +weeks);

d.setText(" " +days);

h.setText(" " +hours);

m.setText(" " +minutes);

s.setText(" " +seconds);

mTextField.setText(smillis + " " + smillis2 + " " +

millicn + "Time remaining: " +weeks +"weeks " +days + " days " + hours

+ " hours: " + minutes+ " minutes: "

+ seconds + " seconds: " );

}

public void onFinish() {

mTextField.setText("done!");

}

}.start();

我想知道如何设定时间以及日期？目前正在午夜时分.我希望它是15:00
