我将通知从服务器发送到我的应用。我想在通知到达时保持通知计数，并且我想在图标上显示，在文本视图上我想通过通知计数可见。
但是问题是我应该在哪里做这些事情？我正在使用FCM，因此当该应用在前景时，请使用OnMessageCeeped。
对于背景，我正在从服务器发送数据有效载荷，但它也只有在单击通知时就会捕获意图。
什么是用户没有单击通知，而只是将其删除？在哪里跟踪这个？
现在我的代码就是这样：
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
private String mOrderId, mBillId;
private Boolean mNotification;
private int notificationCount;
private SessionData sessionData;
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
super.onMessageReceived(remoteMessage);
sessionData = new SessionData(getApplicationContext());
sessionData.add("notificationCount",0);
notificationCount = sessionData.getInt("notificationCount",0);
Log.d(TAG, "From: " + remoteMessage.getFrom());
// Check if message contains a data payload.
if (remoteMessage.getData().size() > 0) {
Log.d(TAG, "Message data payload: " + remoteMessage.describeContents());
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
//get data from server notification.
sendNotification(remoteMessage.getNotification().getBody(), remoteMessage.getNotification().getTitle());
}
//send notification
private void sendNotification(String messageBody, String title) {
mNotification = true;
notificationCount ++;
sessionData.add("notificationCount",notificationCount);
Intent intent = new Intent(this,HomeActivity.class);
if (!messageBody.equals("")) {
intent = new Intent(this, HomeActivity.class);
intent.putExtra("notification", mNotification);
intent.putExtra("title", title);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
}
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0 /* Request code */, intent,
PendingIntent.FLAG_UPDATE_CURRENT);
long[] pattern = {500, 500, 500, 500, 500};
Uri defaultSoundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.login_logo_1)
.setContentTitle(title)
.setContentText(messageBody)
.setAutoCancel(true)
.setVibrate(pattern)
.setSound(defaultSoundUri)
.setContentIntent(pendingIntent);
NotificationManager notificationManager =
(NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
notificationManager.notify(0 /* ID of notification */, notificationBuilder.build());
}
}
在家庭活动中
if (bundle != null) {
if (bundle.getString("title") != null) {
Intent i = new Intent();
i.setAction("com.carryapp.CUSTOM_INTENT"); sendBroadcast(i);
FragmentManager fragmentManager = getFragmentManager();
MainFragment fragment = new MainFragment();
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction().replace(R.id.mycontainer, fragment, "MAIN_FRAGMENT").commitAllowingStateLoss();
fragmentManager = getFragmentManager();
NoticesFragment fragment3 = new NoticesFragment();
Bundle bundle1 = new Bundle();
bundle1.putBoolean("notification",true);
fragment3.setArguments(bundle1);
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction().replace(R.id.mycontainer, fragment3, "NOTICES_FRAGMENT").addToBackStack("H").commit();
}
} else {
FragmentManager fragmentManager = getFragmentManager();
MainFragment fragment = new MainFragment();
fragmentManager.popBackStack(null, FragmentManager.POP_BACK_STACK_INCLUSIVE);
fragmentManager.beginTransaction().replace(R.id.mycontainer, fragment, "MAIN_FRAGMENT").commitAllowingStateLoss();
}
请为此提供帮助。谢谢..
但是问题是我应该在哪里做这些事情？我正在使用FCM 当该应用在前景时，请使用OnMessagereceive。
这是因为您要发送notification-messages。
，如果您要始终称呼onmessagereceed。
，则必须发送数据消息。请参阅FCM文档：
https://firebase.google.com/docs/cloud-messaging/concept-poptions#notifications_and_data_messages
ps：
我将通知从服务器发送到我的应用。我想保持 通知到达时的通知计数，我想 在图标上显示它，在文本视图上，我想与 通知计数。
标准Android不支持图标上的徽章。也许有些发射器将其作为其他功能，但不是Android API。
pps：Android O引入了徽章，但它也自动起作用，因此无需手动更改它
