如何每週都會製作警報通知在剛週五在Android的

Question

我的工作中，我想每星期做上週五通知的應用程序，我已經試過這個代碼，但它使每一天通知

Calendar calendar = Calendar.getInstance(); 
     calendar.set(Calendar.DAY_OF_WEEK,6); 
     calendar.set(Calendar.HOUR_OF_DAY, hourOfDay); 
     calendar.set(Calendar.MINUTE, minute); 
     String h = String.valueOf(hourOfDay); 
     String m = String.valueOf(minute); 
     Intent intent = new Intent(getApplicationContext(), notification.class); 
     pendingIntent = PendingIntent.getBroadcast(getApplicationContext(), 0, intent, PendingIntent.FLAG_UPDATE_CURRENT); 
     alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE); 
     alarmManager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 7*AlarmManager.INTERVAL_DAY, pendingIntent); 
     Toast.makeText(Settings.this, h+ " : " + m , Toast.LENGTH_SHORT).show(); 

Notification.class

public class notification extends BroadcastReceiver { 
    @Override 
    public void onReceive(Context context, Intent intent) { 
    PendingIntent pendingIntent=PendingIntent.getActivity(context,0,new Intent(context,The_main.class),0); 
    NotificationCompat.Builder builder=new NotificationCompat.Builder(context) 
      .setSmallIcon(R.mipmap.awq) 
      .setContentTitle("remainder") 
      .setContentText(" time to read"); 
    builder.setContentIntent(pendingIntent); 
    builder.setDefaults(NotificationCompat.DEFAULT_SOUND); 
    builder.setAutoCancel(true); 
    NotificationManager notificationManager=(NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE); 
    notificationManager.cancel(1); 
    notificationManager.notify(1,builder.build()); 
     }}

嘗試更換

`7*AlarmManager.INTERVAL_DAY` 

7 * 24 * 60 * 60 * 1000 (7days Interval in milliseconds)
