Alarmreceiver如何阻止媒体播放器

Question

AlarmReceiver.class

public void onReceive(Context context, Intent intent) { 

     // Uri uri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_ALARM); 


     if (mp.isPlaying()) { 
      stopPlaying(); 
      mp.stop(); 
     } 
     else { 
      stopPlaying(); 
      mp = MediaPlayer.create(context, R.drawable.aaz); 
      mp.start(); 
     } 

} 


private void stopPlaying() { 
     if (mp != null) { 
      mp.stop(); 
      mp.release(); 
      mp = null; 
     }} 

这台当达到计时器那么它西港岛线播放音频报警。

以下代码来自Mainactivity。

private void setAlarm(Calendar targetCal) { 
     textAlarmPrompt.setText(
       "\n\n***\n" 
         + "Alarm is set@ " + targetCal.getTime() + "\n" 
         + "***\n"); 

     Intent intent = new Intent(getBaseContext(), AlarmReceiver.class); 
     PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0); 
     AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
     alarmManager.set(AlarmManager.RTC_WAKEUP, targetCal.getTimeInMillis(), pendingIntent); 

    } 

停机报警：但音频没有停止，当这个代码是触发AlarmReceiver.class。

以下代码来自Mainactivity。

private void cancelAlarm() { 

      textAlarmPrompt.setText(
        "\n\n***\n" 
          + "Alarm Cancelled! \n" 
          + "***\n"); 




      Intent intent = new Intent(getBaseContext(), AlarmReceiver.class); 
      PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RQS_1, intent, 0); 
      AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE); 
      alarmManager.cancel(pendingIntent); 


     }

做服务来处理报警，您可以通过设置您的报警时间表startService处理，并停止在stopService
