報警通知

Question

現在任何人都可以使用AlarmManager/service在特定時間和選定的時間間隔內播放通知或聲音或振動。從6:00 PM喜歡用15分鐘

Answer 1

定期間隔下午9:00加入的Manifest.xml：

... 
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> 
... 
<receiver android:process=":remote" android:name="Alarm"></receiver> 
... 

代碼：

public class Alarm extends BroadcastReceiver 
{  
    @Override 
    public void onReceive(Context context, Intent intent) 
    { 
     PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE); 
     PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "My Tag"); 
     wl.acquire(); 

     Toast.makeText(context, "Alarm !!!!!!!!!!", Toast.LENGTH_LONG).show(); 
     // Put here your vibration and sound notifycation 
     wl.release(); 
    } 

    public void SetAlarm(Context context) 
    { 
     AlarmManager am=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE); 
     Intent i = new Intent(context, Alarm.class); 
     PendingIntent pi = PendingIntent.getBroadcast(context, 0, i, 0); 
     am.setRepeating(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(), 1000 * 60 * 15, pi); 
    } 

    public void CancelAlarm(Context context) 
    { 
     Intent intent = new Intent(context, Alarm.class); 
     PendingIntent sender = PendingIntent.getBroadcast(context, 0, intent, 0); 
     AlarmManager alarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 
     alarmManager.cancel(sender); 
    } 
}
