報警不起作用

報警在項目中不能正常工作，報警已成功設置，但它們沒有設備和模擬器的響應，任何人都可以提前幫助我！

當你設置AlarmManager.RTC_WAKEUP喲ü正在廣播，所以你需要一個廣播接收器，在接收時啓動報警活動
例如，當你按下設置報警按鈕

public void onClick(View v) { 
      Intent intent = new Intent(getBaseContext(), AlarmBroadcastReciever.class); 
      intent.putExtra("message", "alarm 1 starts"); 
      PendingIntent alarmIntent = PendingIntent.getBroadcast(getBaseContext(), 0, intent, 0); 
      long startTime = ... 
      AlarmManager alm = (AlarmManager) getSystemService(ALARM_SERVICE); 
      alm.set(AlarmManager.RTC_WAKEUP, startTime, alarmIntent); 
      Toast.makeText(.....Toast.LENGTH_LONG).show(); 
     } 
    }; 

現在你需要的AlarmBroadcastReciever

public class AlarmBroadcastReciever extends BroadcastReceiver { 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     String msg = intent.getStringExtra("message"); 
     Toast.makeText(context, msg, Toast.LENGTH_SHORT).show(); 
     Intent alarmPage = new Intent(context, Alarm.class); 
     alarmPage.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     context.startActivity(alarmPage); 
    } 

}
