如何让我的闹钟在android里响1分钟？

Question

我需要在我的application.But上敲1分钟的闹钟，它只响一秒钟。

请给我建议。谢谢你宝贵的时间！

请找我的资料来源供参考。

AndroidAlarmService.java

public class AndroidAlarmService extends Activity {

private PendingIntent pendingIntent;
private static final int PERIOD=60000; // 1 minute

 /** Called when the activity is first created. */

@Override
public void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.main);

 Intent myIntent = new Intent(AndroidAlarmService.this, RepeatingAlarm.class);
 pendingIntent = PendingIntent.getBroadcast(AndroidAlarmService.this, 0, myIntent, 0);

 AlarmManager aM = (AlarmManager)getSystemService(ALARM_SERVICE);

 Calendar c=Calendar.getInstance();
 c.set(Calendar.HOUR, 6);
 c.set(Calendar.MINUTE, 0);
 c.set(Calendar.SECOND, 0);

  PendingIntent pi = PendingIntent.getBroadcast(getApplicationContext(), 0, new Intent(getApplicationContext(),AndroidAlarmService.class),PendingIntent.FLAG_UPDATE_CURRENT);


 aM.setRepeating(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(),PERIOD,pendingIntent);

    }
 }

RepeatingAlarm.java

 public class RepeatingAlarm extends BroadcastReceiver
{
    @Override
    public void onReceive(Context context, Intent intent)
    {   
        AlarmManager mgr = (AlarmManager)context.getSystemService(Context.ALARM_SERVICE);

        Toast.makeText(context,"Alarm Started.....", Toast.LENGTH_LONG).show();


        Uri notification = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        Ringtone r = RingtoneManager.getRingtone(context, notification);
        r.play();

        // Vibrate the mobile phone
        Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(500);

        }
    }

我想用铃声你不会成功的。这里有一个关于循环铃声的小帖子：

但我还没试过。相反，您可以使用MediaPlayer循环并创建一个自定义倒计时器来停止mediaPlayer onFinished()。但这只是一个可能的解决办法..。

        try {

     Uri ringtoneAlert =  RingtoneManager.
        getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);

         mRingtoneLooper = new MediaPlayer();
         mRingtoneLooper.setDataSource(this, ringtoneAlert);

     final AudioManager audioRingtoneManager = (AudioManager) getSystemService(Context.AUDIO_SERVICE);

     if (audioRingtoneManager.getStreamVolume(AudioManager.STREAM_RING) != 0) {

            mRingtoneLooper.setAudioStreamType(AudioManager.STREAM_RING);
            mRingtoneLooper.setLooping(true);
            mRingtoneLooper.prepare();
            mRingtoneLooper.start();

            //start custom countdown timer for 60 seconds, counts every second down
            //counting every second down is not necessary, You could even set every 5 seconds or whatever You want

            RingtoneStopper stopper = new RingToneStopper(60000,1000);
            stopper.start();
       }
     } catch(Exception e) {

      //do some message to user if some error occurs
   } 

     //define a countdown timer for 60 seconds that stops the MediaPlayer


        public class RingtoneStopper extends CountDownTimer{

             public RingtoneStopper(long millisInFuture, long countDownInterval) {
                  super(millisInFuture, countDownInterval);
              }

                   @Override
                     public void onFinish() {
                        mRingtoneLooper.stop();
                 }

                   @Override
             public void onTick(long millisUntilFinished) {
                  //need nothing to do on tick events
                 }
                }

请检查这段代码，我想这会对你有帮助的。

Ringtone _ringtone =  RingtoneManager.getRingtone(context, notification);
Timer _start_ringtone = new Timer();
    while (_ringtone!=null) {
if(!_ringtone.isPlaying()){
        _ringtone.play();
}
    }
    _start_ringtone.schedule(new TimerTask() {
        @Override
        public void run() {
            _ringtone.stop();
_ringtone=null;
        }
    }, 60000);
