intent.getExtra在將數據從活動傳遞到BroadcastReceiver時返回null

Question

    Intent intent=new Intent(this, AlarmReceiver.class);
    intent.putExtra("Test","Test Intent");
    PendingIntent pendingIntent=PendingIntent.getBroadcast(this,0,intent,0);
    alarmManager.set(AlarmManager.RTC_WAKEUP,System.currentTimeMillis()+2000,pendingIntent);

在BroadcastReceiver中，onReceive（）

   String test=intent.getStringExtra("Test");

將數據從活動傳遞到BroadcastReceiver時，Intent.getExtra返回null？ 請幫忙

這是正確的方法-指定一個標志！

PendingIntent pendingIntent = PendingIntent.getBroadcast(this, uniqueRequestCode, intent, PendingIntent.FLAG_UPDATE_CURRENT);
