如何在timePicker中播放铃声

Question

我正在尝试构建一个警报时钟应用程序。 TimePicker正在运行，但如何在选择时间后让它做某事？我正在尝试播放铃声动作。

这是TimePicker类：

public  class TimePickerFragment extends DialogFragment implements TimePickerDialog.OnTimeSetListener {

private  int hours;
private  int minutes;
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    final Calendar c = Calendar.getInstance();
    int hour = c.get(Calendar.HOUR_OF_DAY);
    int min = c.get(Calendar.MINUTE);

    return new TimePickerDialog(getActivity(), this, hour, min,
            DateFormat.is24HourFormat(getActivity()));

}

@Override
public void onTimeSet(android.widget.TimePicker view, int hourOfDay, int minute) {
    hours = hourOfDay;
    minutes = minute;

    if(hours == Calendar.HOUR_OF_DAY && minutes == Calendar.MINUTE){
        Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone r = RingtoneManager.getRingtone(getContext(), notification);
        r.play();
    }
}

}

这是激活TimePicker的按钮：

timePicker = (Button)findViewById(R.id.TimePickerButton);

timePicker.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        DialogFragment newFragment = new TimePickerFragment();
        newFragment.show(getFragmentManager(), "pickerTime");

    }
});

您必须删除

if(hours == Calendar.HOUR_OF_DAY && minutes == Calendar.MINUTE){
}
