单击按钮时，我试图触发警报。但它不起作用这里有什么问题。

警报集.java

private void setAlarm() {   
    //Alarm 
    Toast.makeText(getApplicationContext(), "alerm set", Toast.LENGTH_LONG).show();


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

   AlarmManager alarmManager = (AlarmManager)getSystemService(ALARM_SERVICE);
   alarmManager.set(AlarmManager.RTC, (System.currentTimeMillis(), pendingIntent);

    //Alarm END
}

报警接收器.java

public class AlarmReceiver extends BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {

    System.out.println("ALARM SUCCESS");
    // TODO Auto-generated method stub
    Toast.makeText(context, "Don't panik but your time is up!!!!.",
            Toast.LENGTH_LONG).show();
    // Vibrate the mobile phone
    Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
    vibrator.vibrate(2000);

    Intent service1 = new Intent(context, MyAlarmService.class);
    context.startService(service1);
} 
}

MyAlarmService.java

public class MyAlarmService extends Service 

{
private NotificationManager mManager;

@Override
public IBinder onBind(Intent arg0)
{
    // TODO Auto-generated method stub
    return null;
}

@Override
public void onCreate() 
{
    // TODO Auto-generated method stub  
    super.onCreate();
}

@SuppressWarnings({ "static-access", "deprecation" })
@Override
public void onStart(Intent intent, int startId)
{
    super.onStart(intent, startId);

    mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);
    Intent intent1 = new Intent(this.getApplicationContext(),CurrentParking.class);

    Notification notification = new Notification(R.drawable.ic_launcher,"This is a test message!", System.currentTimeMillis());

    intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP| Intent.FLAG_ACTIVITY_CLEAR_TOP);

    PendingIntent pendingNotificationIntent = PendingIntent.getActivity( this.getApplicationContext(),0, intent1,PendingIntent.FLAG_UPDATE_CURRENT);
    notification.flags |= Notification.FLAG_AUTO_CANCEL;
    notification.setLatestEventInfo(this.getApplicationContext(), "Sweeper Stopper", "This is a test message!", pendingNotificationIntent);

    mManager.notify(0, notification);
}

@Override
public void onDestroy() 
{
    // TODO Auto-generated method stub
    super.onDestroy();
}

}

Intent myIntent = new Intent(this, AlarmManager.class);

在这一行更改AlarmManager.class为 AlarmReceiver.class

可能是你的警报。set 方法有错误

改变

alarmManager.set(AlarmManager.RTC, (System.currentTimeMillis(), pendingIntent);

至

Calendar cal = Calendar.getInstance();
alarmManager.set(AlarmManager.RTC,cal.getTimeInMillis(), pendingIntent);

还要检查您的 pendingIntent 声明。

自定义广播：

private void setAlarm() {   
    //Alarm 
    Toast.makeText(getApplicationContext(), "alerm set", Toast.LENGTH_LONG).show();


   Intent intent = new Intent();
   intent.setAction("com.example.Broadcast.start");
   sendBroadcast(intent);

    //Alarm END
}

现在，在清单中

<receiver
            android:name="AlarmReceiver">

            <intent-filter>

                <action android:name="com.device.Broadcast.start" />

            </intent-filter>
</receiver>

现在，AlarmReceiver 公共类 AlarmReceiver 扩展 BroadcastReceiver{

@Override
public void onReceive(Context context, Intent intent) {

 if(intent.getAction().equals("com.device.Broadcast.start")){
// Do the what you want
}

 }
 }
