两个对话片段之间的通信

AddAlarmDialogFragment )使用自定义布局,单击TextView后将启动另一个 TimePickerFragment .

    @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

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

    return new TimePickerDialog(getActivity(),TimePickerDialog.THEME_HOLO_LIGHT, this, hour, minute,
            true);

}

我让TimePickerFragment实现 TimePickerDialog.OnTimeSetListener, onTimeSet(TimePicker view, int hourOfDay, int minute) .

    public interface OnTimePickedListener {
     void timePicked(int hour, int minutes);
}

方法 timePicked(int hour, int minutes) onTimeSet(时间选择器视图,int hourOfDay,int minute)

这是回调的全部代码

        @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        OnTimePickedListener onTimePickedListener=
OnTimePickedListener)getParentFragment();
        onTimePickedListener.timePicked(hourOfDay,minute);
    }

这里有一个问题,我想从中消磨时间 TimePickerDialog 添加AlarmDialogFragment ,因此启动的DialogFragment 时间选择器碎片

有没有办法从父dialogFragment获取此接口的实例。或者也许有更好的方式在这两个组件之间提供通信,因为对我来说 OnTimePickedListener TimePickerDialog.OnTimeSetListener 似乎不知道是什么让代码变得干净。
