我的接收者没有收到意图

Question

我遇到了这个问题：我为 alarmManager 设置了 intent 和 pendingintent，如果满足某些条件，则在 intent 中添加一些额外内容。问题是我的接收器没有读取我的附加信息：

在 MainActivity 中设置 alarmManager:

    AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    Intent i = new Intent(MainActivity.this, AlarmReceiver.class);
    PendingIntent pi = PendingIntent.getBroadcast(MainActivity.this , 0, i, PendingIntent.FLAG_ONE_SHOT);

       // conditions 
                    i.putExtra("type", 1);
                    i.putExtra("mealType", 2);
                    Log.d(TAG , "type: " + i.getExtras().getInt("type"));
                    Log.d(TAG , "mealtype: " + i.getExtras().getInt("mealType"));
                    calendar.set(calendar.HOUR_OF_DAY, 7);
                    am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pi);

在 logcat 中我可以看到：

D/MAIN: type: 1
D/MAIN: mealtype: 2

但在我的接收器中：

public void onReceive(Context context, Intent intent) {

    /**
     * Receiver
     */
    Log.d(TAG, "Allarme ricevuto dal receiver");

    int type = intent.getExtras().getInt("type");
    Log.d(TAG , "type: " + type);
    Log.d(TAG , "mealtype: " + intent.getExtras().getInt("mealType"));
    Log.d(TAG , "unExisted: " + intent.getExtras().getInt("unExisted"));



    if(type == 0){
        Intent service = new Intent(context, AlarmService.class);
        service.putExtra("type", type);
        context.startService(service);
    }

    if(type == 1){
        int mealType = intent.getExtras().getInt("mealType");

        Intent service1 = new Intent(context, AlarmService.class);
        service1.putExtra("type", type);
        service1.putExtra("mealType", mealType);
        context.startService(service1);
    }
}

我看到了这个：

D/ALARM RECEIVER: Allarme ricevuto dal receiver
D/ALARM RECEIVER: type: 0
D/ALARM RECEIVER: mealtype: 0
D/ALARM RECEIVER: unExisted: 0

我看到所有的键都为 0，也看到为 0 "unExistest"，我从来没有在意图中插入这个键。为什么？

您需要在创建 PendingIntent 之前设置 Intent extras。

示例：

AlarmManager am = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
Intent i = new Intent(MainActivity.this, AlarmReceiver.class);
i.putExtra("type", 1);
i.putExtra("mealType", 2);
PendingIntent pi = PendingIntent.getBroadcast(MainActivity.this , 0, i, PendingIntent.FLAG_ONE_SHOT);
calendar.set(calendar.HOUR_OF_DAY, 7);
am.set(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), pi);
