java如何在安卓中从计时器获取小时和分钟

Question

这是我给时间选择器的代码

时间选择器。爪哇

public class TimePicker extends EditText implements
    安卓.app.TimePickerDialog.OnTimeSetListener {
public interface OnTimeSetListener {
    public void onTimeSet(TimePicker view, int hour, int minute);
}

protected int hour;
protected int minute;
protected OnTimeSetListener onTimeSetListener;
protected java.text.DateFormat timeFormat;

public int getHour() {
    return hour;
}

public OnTimeSetListener getOnTimeSetListener() {
    return onTimeSetListener;
}

public void setOnTimeSetListener(OnTimeSetListener onTimeSetListener) {
    this.onTimeSetListener = onTimeSetListener;
}

public void setHour(int hour) {
    this.hour = hour;
    updateText();
}

public int getMinute() {
    return minute;
}

public void setNow() {
    Calendar c = Calendar.getInstance();
    setTime(c.get(Calendar.HOUR_OF_DAY), c.get(Calendar.MINUTE));
}

public void setMinute(int minute) {
    this.minute = minute;
    updateText();
}

public void setTime(int hour, int minute) {
    this.hour = hour;
    this.minute = minute;
    updateText();
}

public TimePicker(Context context, AttributeSet attrs) {
    super(context, attrs);

    timeFormat = DateFormat.getTimeFormat(getContext());

    setInputType(InputType.TYPE_DATETIME_VARIATION_DATE);
    setFocusable(false);
    setNow();
}

protected void showTimePicker() {
    TimePickerDialog timePickerDialog;

    timePickerDialog = new TimePickerDialog(getContext(), this, getHour(),
            getMinute(), true);
    timePickerDialog.show();
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    if (event.getAction() == MotionEvent.ACTION_DOWN)
        showTimePicker();

    return super.onTouchEvent(event);
}

public java.text.DateFormat getTimeFormat() {
    return timeFormat;
}

public void setTimeFormat(java.text.DateFormat timeFormat) {
    this.timeFormat = timeFormat;
    updateText();
}

@Override
public void onTimeSet(安卓.widget.TimePicker view, int hour, int minute) {
    // TODO Auto-generated method stub
    setTime(hour, minute);
    clearFocus();

    if (onTimeSetListener != null){
        onTimeSetListener.onTimeSet(this, hour, minute);
    }

}

public void updateText() {
    Calendar cal = new GregorianCalendar(0, 0, 0, getHour(), getMinute());
    setText(timeFormat.format(cal.getTime()));
}

}

活动日历。xml

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:安卓="http://schemas.安卓.com/apk/res/安卓"
    xmlns:tools="http://schemas.安卓.com/tools"

    安卓:layout_gravity="center"
    安卓:background="@color/maroon"
    tools:context="com.gpplsmje.mac.calendar.CalendarEvents" >

    <com.gpplsmje.mac.calendar.utils.TimePicker
        安卓:id="@+id/alarm_time"
        style="@安卓:style/Widget.Holo.Light.Spinner"
        安卓:layout_width="fill_parent"
        安卓:layout_height="wrap_content"

    </RelativeLayout>

日历事件。爪哇

public class CalendarEvents extends Activity implements OnClickListener {
    TimePicker notifyTime;

Button back, cancel, done;
int hour, minute, day, month, year;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.calendar_events);
    onNewIntent(getIntent());

    notifyTime = ((TimePicker) findViewById(R.id.alarm_time));
    notifyTime.setTimeFormat(DateFormat.getTimeFormat(this));

    hour = notifyTime.getHour();
    minute = notifyTime.getdMinute();

    done.setOnClickListener(this);
}
@Override
public void onClick(View v) {
    switch (v.getId()){
    case R.id.bDone:
        Toast.makeText(this, year + " " + month + " " + day + " " + hour + " " + minute , Toast.LENGTH_LONG).show();
        break;
    }
}

我发了一条Toast消息来检查我从TimePicker中选择的内容是否正确。但每次我运行这段代码时，它总是给出我机器上的当前时间，而不是我从TimePicker中选择的时间。我如何做到这一点？谁能帮帮我吗？提前谢谢

使用这个方法setOnTimeChangedListener(TimePicker.OnTimeChangedListener onTimeChangedListener)

这节课是在和时间选择器一起工作的时候timepicker

一点也不介意
