我有一个应用程序,我在GCM
中获得GcmListenerService
推送通知(如gcm android示例中所示)。每当我收到通知时,我会得到一些JSON
,其中包含与显示通知相关的数据。
现在假设我收到一条通知,其中有人为我添加了书签,因为我获得了该用户的pk
(标识符),当我点击通知时,它会使用{{ 1}}在推送通知中收到,以显示该用户的个人资料。
问题:如果我收到上述类型的2条通知,那么无论我点击哪个通知,我都会查看我最近收到通知的人的个人资料。
在其他通知之上获取通知是否会覆盖以前通知的值,以便只有最新通知才有效?这是否意味着我只能从应用中显示一个推送通知?如果需要,我可以发布代码。
相关代码:
pk
其他内部代码:
@Override
public void onMessageReceived(String from, Bundle data) {
tinyDB = new TinyDB(this);
if (tinyDB.getBoolean(AppConstants.LOGIN_STATE, false)) {
try {
Log.i("NOTIF", data.toString());
String screen = data.getString("screen");
String dataJson = data.getString("data");
String displayJson = data.getString("display");
String notification_id = data.getString("notif_id");
String priority = data.getString("priority");
String style = data.getString("style");
Gson gson = new GsonBuilder().disableHtmlEscaping().create();
NotificationVal notificationVal = gson.fromJson(displayJson, NotificationVal.class);
String title = notificationVal.getTitle();
String text = notificationVal.getText();
String largeText = notificationVal.getLargeText();
String smallIcon = notificationVal.getSmallIcon();
String largeIcon = notificationVal.getLargeIcon();
Bitmap smallImage = null;
Bitmap largeImage = null;
if (!TextUtils.isEmpty(smallIcon)) {
smallImage = getBitmapFromURL(smallIcon);
}
if ("big_picture".equalsIgnoreCase(style) && (largeImage != null)) {
NotificationCompat.BigPictureStyle notificationStyle = new NotificationCompat.BigPictureStyle();
notificationStyle.setBigContentTitle(title);
notificationStyle.setSummaryText(text);
notificationStyle.bigPicture(largeImage);
Intent intent = NotificationIntentBuilder.get(this, dataJson, screen, smallIcon, largeIcon, notification_id);
TaskStackBuilder stackBuilder = NotificationStackBuilder.get(this, screen, dataJson);
stackBuilder.addNextIntent(intent);
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(this);
mBuilder.setSmallIcon(R.drawable.white_square);
mBuilder.setAutoCancel(true);
mBuilder.setColor(Color.parseColor("#fac80a"));
mBuilder.setLargeIcon(largeImage);
mBuilder.setContentTitle(title);
mBuilder.setContentText(text);
mBuilder.setContentIntent(resultPendingIntent);
mBuilder.setDefaults(NotificationCompat.DEFAULT_VIBRATE);
mBuilder.setDefaults(NotificationCompat.DEFAULT_SOUND);
mBuilder.setPriority(NotificationCompat.PRIORITY_HIGH);
mBuilder.setStyle(notificationStyle);
mBuilder.setContentIntent(resultPendingIntent);
NotificationManager mNotificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
if (notification_id != null) {
mNotificationManager.cancel(Integer.parseInt(notification_id));
mNotificationManager.notify(Integer.parseInt(notification_id), mBuilder.build());
}
} else {
Log.i("GCM", "Dummy Notification");
}
} catch (Exception e) {
Log.i("NOTIF", "An exception occurred");
}
}
}
编辑两个不同类型的通知(打开不同的活动)不会发生此问题,只会在通知打开同一屏幕时发生。
编辑1 以下是推送通知中收到的值:
public class NotificationStackBuilder {
public static TaskStackBuilder get(Context context, String screen, String data) {
if ("IMAGE".equalsIgnoreCase(screen)) {
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(ImageActivity.class);
return stackBuilder;
} else {
TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
stackBuilder.addParentStack(NewHomeActivity.class);
return stackBuilder;
}
}
}
public class NotificationIntentBuilder {
public static Intent get(Context context, String data, String screen, String smallIcon, String largeIcon, String notificationId) {
if ("IMAGE".equalsIgnoreCase(screen)) {
String pk = "";
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(data);
if (jsonObject.has("pk")) {
pk = jsonObject.getString("pk");
}
} catch (JSONException e) {
e.printStackTrace();
}
Intent intent = new Intent(context, ImageActivity.class);
intent.putExtra("ID", pk);
intent.putExtra("notificationId", notificationId);
return intent;
} else if ("GALLERY".equalsIgnoreCase(screen)) {
String pk = "";
JSONObject jsonObject = null;
try {
jsonObject = new JSONObject(data);
if (jsonObject.has("pk")) {
pk = jsonObject.getString("pk");
}
} catch (JSONException e) {
e.printStackTrace();
}
Intent intent = new Intent(context, GalleryActivity.class);
intent.putExtra("ID", pk);
intent.putExtra("notificationId", notificationId);
return intent;
} else {
return new Intent(context, NewHomeActivity.class);
}
}
}
这个有Bundle[{google.sent_time=1469254984538, priority=0, screen=IMAGE, data={"pk":650}, style=big_picture, google.message_id=0:1469254984541527%e07f0e28f9fd7ecd, notif_id=4267, display={"large_icon":"https:\/\/d2r0rrogy5uf19.cloudfront.net\/photos\/971c03f8-6a5d-30a3-9e49-0ab416cb8fa0.jpg","small_icon":"","text":"Random hi5'd your photo to 'Diwali'","title":"random","large_text":""}, collapse_key=do_not_collapse}]
为4267,现在假设我收到同一个屏幕的另一个通知,notificationId
说4268,然后当我记录图像屏幕中收到的notificationId
时,打开两个通知我得到4268。
编辑2 我想这个问题与notificationId
有关。以下是文档中的内容:
PendingIntent.FLAG_UPDATE_CURRENT
这就是发生的事情。意图附加内容被最新通知的意图附加内容覆盖。所以,我尝试使用Flag indicating that if the described PendingIntent already exists, then keep it but replace its extra data with what is in this new Intent.
,但是我可以打开旧的意图,但是当我点击最新的意图时会注意到。
我希望这两个通知都在推送通知列表中,并且它们都应该在具有不同意图附加值的相应屏幕上。
答案 0 :(得分:1)
您需要为每个通知提供唯一的请求代码,否则它将被替换为新的通知。
摘自PendingIntent documentation:
数组中的最后一个意图表示PendingIntent的键。 换句话说,它是匹配的重要元素(如已完成 给getActivity的单一意图(Context,int,Intent, int),其内容将成为send的替换主题(Context, int,Intent)和FLAG_UPDATE_CURRENT等。这是因为它是 最具体的提供意图,以及用户实际的UI 看到意图何时开始。
所以请替换以下行:
PendingIntent resultPendingIntent = stackBuilder. getPendingIntent(0,
PendingIntent.FLAG_UPDATE_CURRENT);
假设notification_id
是唯一整数,只需将其替换为如下:
PendingIntent resultPendingIntent =
stackBuilder.getPendingIntent(Integer.parseInt(notification_id)
, PendingIntent.FLAG_UPDATE_CURRENT);
