Android 具有 PendingIntent 的通知的额外空值

Question

我正在尝试在点击通知时向 Activity 发送一个 int Extra。当我点击通知时 activity 启动，但额外的总是空的。

查了很多类似的问题都没有帮我解决问题。（我尝试使用 onNewIntent() 但从未调用过）。如何才能成功发送Extra？

这是创建意图的 BroadcastReceiver：

public class EventAlarmNearReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {

        Intent nextIntent = new Intent().setClass(context, EventActivity.class);
        nextIntent.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
        int id = 1234;
        nextIntent.putExtra("Id", (long) id);
        nextIntent.setAction("nearReceiverAction");
        PendingIntent nextPendingIntent = PendingIntent.getActivity(context, 1022, nextIntent, PendingIntent.FLAG_UPDATE_CURRENT);

        String text = "Your " + intent.getStringExtra("Name") + " is starting soon. Please read your documents.";

        NotificationsDeliver.getInstance().sendNotification(context, "Meeting Mate", text, nextPendingIntent);
    }
}

这是发送通知的 NotificationsDeliver 方法：

public void sendNotification(@NonNull Context context, String title, String text, PendingIntent pendingIntent ) {
        NotificationCompat.Builder builder = new NotificationCompat.Builder(context, CHANNEL_ID)
                .setSmallIcon(R.drawable.ic_event_note_white_24dp)
                .setContentTitle(title)
                .setContentText(text)
                .setPriority(NotificationCompat.PRIORITY_HIGH)
                .setVibrate(new long[] { 1000, 1000, 1000 })
                .setContentIntent(pendingIntent)
                .setAutoCancel(true);

        NotificationManagerCompat notificationManager = NotificationManagerCompat.from(context);

        // notificationId is a unique int for each notification that you must define
        notificationManager.notify(999, builder.build());
    }

这是事件的 onCreate 方法Activity:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    Intent intent = getIntent();
    long id = intent.getLongExtra("id", 0);
}

我猜这是因为你在投入和获得额外时使用了不同的 "id" 这个词；比较：

nextIntent.putExtra("Id", (long) id);
//                  ^^^^

对

long id = intent.getLongExtra("id", 0);
//                            ^^^^

尝试对两者使用相同的大小写。
