        int hour = c.get(Calendar.HOUR_OF_DAY);
        int minute = c.get(Calendar.MINUTE);

        // Create a new instance of TimePickerDialog and return it
        return new TimePickerDialog(getActivity(), this, hour, minute,
                DateFormat.is24HourFormat(getActivity()));
    }




    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        // Do something with the time chosen by the user
    }



}

TimePickerDialog.java

public interface TimePickerDialog {

    public interface OnTimeSetListener {

    }

}

我如何完成此解决方案？
有什么想法吗？

Answer 1

检查一下。这是我在我的例子中使用的那个......

    private TimePickerDialog showTimePicker(){
    TimePickerDialog timePicker = new TimePickerDialog(MainActivity.this, new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
            // TODO Auto-generated method stub
            mCalendar.set(Calendar.HOUR_OF_DAY, hourOfDay);
            mCalendar.set(Calendar.MINUTE, minute);
            mToday.set(Calendar.HOUR_OF_DAY, hourOfDay);
            mToday.set(Calendar.MINUTE, minute);
            updateTimeButtonText();

        }
    }, mCalendar.get(Calendar.HOUR_OF_DAY), mCalendar.get(Calendar.MINUTE), true);
    return timePicker;
}

Answer 2

使用此类

public static class TimePickerFragment extends DialogFragment
                        implements TimePickerDialog.OnTimeSetListener {

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    // Use the current time as the default values for the picker
    final Calendar c = Calendar.getInstance();
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int minute = c.get(Calendar.MINUTE);

    // Create a new instance of TimePickerDialog and return it
    return new TimePickerDialog(getActivity(), this, hour, minute,
            DateFormat.is24HourFormat(getActivity()));
}

public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
    // Do something with the time chosen by the user
}

}

public void showTimePickerDialog(View v) {
DialogFragment newFragment = new TimePickerFragment();
newFragment.show(getSupportFragmentManager(), "timePicker");

}

//在OnClick事件上调用showTimeDialog。你必须传递视图ID。

//并且在onTimeSet方法中，您可以设置edittext内容。

如果它不起作用，请告诉我。

使用对话框片段启动时间戳
