CalendarEvents.java

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Toast条消息来检查我从TimePicker中选择的内容是否正确。但每次我运行此代码时，它总是给我机器上的当前时间，而不是我从TimePicker中选择的时间。我该如何做到这一点？谁能帮帮我吗？提前谢谢。

Answer 1

使用此方法setOnTimeChangedListener(TimePicker.OnTimeChangedListener onTimeChangedListener)

和使用timepicker时的这个类。 timepicker

没有onclick听众..

Answer 2

如果您在onClick()处理程序中清除TimePicker的焦点，则可以使用其公共methods将所选时间值作为整数：

public void onClick(View v) {
    ...
    notifyTime = ((TimePicker) findViewById(R.id.alarm_time));
    notifyTime.clearFocus();

    hour = notifyTime.getCurrentHour();
    minute = notifyTime.getCurrentMinute();
    ....
}

Answer 3

要阅读用户输入的时间，请使用监听器

private TimePickerDialog.OnTimeSetListener mTimeSetListener =
    new TimePickerDialog.OnTimeSetListener() {
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            mHour = hourOfDay;
            mMinute = minute;
            updateDisplay();
        }
    };

Answer 4

这样你就可以得到时间

Calendar mCalendar = Calendar.getInstance();

 mHour = mCalendar.get(Calendar.HOUR_OF_DAY);
 mMinute = mCalendar.get(Calendar.MINUTE);

 TimePickerDialog timePickerDialog = new TimePickerDialog(mActivity, mTimeSetListener, mHour, mMinute, false);

 private TimePickerDialog.OnTimeSetListener mTimeSetListener = new TimePickerDialog.OnTimeSetListener() {
     public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

         mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
         mCalendar.set(Calendar.MINUTE, mMinute);
         SimpleDateFormat mSDF = new SimpleDateFormat("hh:mm a");
         String time = mSDF.format(mCalendar.getTime());
     }
 }
