Question

我正在显示附加到我的项目的库的通知，当点击通知时，通知将转到活动（ReceivingActivity）。单击通知后，活动将打开，但不会收到附加到其中的附加内容。

通知触发代码 - 当我收到gcm消息并且通知代码在库中时，我调用sendNotification

public static final int NOTIFICATION_ID = 1;
private NotificationManager mNotificationManager;
NotificationCompat.Builder builder;
private void sendNotification(Bundle extras) {
    mNotificationManager = (NotificationManager)
            this.getSystemService(Context.NOTIFICATION_SERVICE);



    Intent redirectIntent = new Intent(this, Class.forName("com.xyz.kljdf.ReceivingActivity"));
            redirectIntent.putExtra("key", "value"); // These extras are not received in ReceivingActivity onCreate(), see the code below




    PendingIntent contentIntent = PendingIntent.getActivity(this, 0,
            redirectIntent, 0);

    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
    .setSmallIcon(((Context)this).getResources().getIdentifier("icon", "drawable", getPackageName()))
    .setContentTitle(extras.getString(PushConstants.TITLE))
    .setStyle(new NotificationCompat.BigTextStyle()
    .bigText(extras.getString(PushConstants.ALERT)))
    .setContentText(extras.getString(PushConstants.ALERT));

    mBuilder.setContentIntent(contentIntent);
    mNotificationManager.notify(NOTIFICATION_ID, mBuilder.build());
}

检查ReceivingActivity中的附加内容......

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_receiving);


        Log.i("extras..... @@@@@@", getIntent().getExtras().toString()); //NPE here


    }

我需要帮助来弄清楚如何传递额外内容并正确接收它们。

确保PendingIntent在调用时实际传递数据。请参阅此答案以获得解释：https://stackoverflow.com/a/3851414/1426565

对于其他任何人来说，如果你肯定意图已经存在并且只是被带到了前面，那么新的Intent数据默认不会传递给它。你可以覆盖onNewIntent（Intent）以解决这个问题：

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);
    setIntent(intent); // Set the new Intent's data to be the currently passed arguments
}
