当app在后台时，如何在收件箱样式中添加fcm通知？
当我添加以下代码时，我在应用程序打开时获得了收件箱样式
但如果应用是后台，则会显示单独的通知
public class MyFirebaseMessagingService extends FirebaseMessagingService {
private static final String TAG = "MyFirebaseMsgService";
Integer notify_no = 0;
Integer numMessages = 0;
DBHelper db = new DBHelper(this);
private final int notificationID = 237;
private static int value = 0;
// Notification.InboxStyle inboxStyle = new Notification.InboxStyle();
//Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.newlogo);
// TODO(developer): Handle FCM messages here.
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.getData());
/* Integer badge = Integer.parseInt(remoteMessage.getData().get("badge"));
Log.d("notificationNUmber",":"+badge);
setBadge(getApplicationContext(), badge);*/
}
// Check if message contains a notification payload.
if (remoteMessage.getNotification() != null) {
Log.d(TAG, "Message Notification Body: " + remoteMessage.getNotification().getBody());
}
Intent intent = new Intent();
intent.setAction("com.ksoft.propreka.CUSTOM_INTENT");
sendBroadcast(intent);
db.insertNotification(remoteMessage.getNotification().getBody(),remoteMessage.getData().get("room_id"));
//EventBus.getDefault().post(remoteMessage.getNotification().getBody());
//
try {
if (remoteMessage.getNotification() != null) {
sendNotification(remoteMessage.getData().get("text"));
} else if (!remoteMessage.getData().isEmpty()) {
sendNotification(remoteMessage.getData().get("text"));
}
} catch (Exception e) {
Log.d("json error", e.toString());
}
//sendNotification(remoteMessage.getData().get("text"));
Log.d("test",":test notification");
//createpushnotification();
// Also if you intend on generating your own notifications as a result of a received FCM
// message, here is where that should be initiated. See sendNotification method below.

如何添加收件箱样式？

使用数据有效负载发送通知数据并使用此类向手机显示。
例如：
使用通知有效负载
this.getFullCourseBySlug(slug)
.switchMap(course => this.getTeacherIdsPerCourse(course))
.map(([teacherIds, course]) => {
const arrayOfObservables = new Array<Observable>();
for(let id of teacherIds) {
arrayOfObservables.push(this.getTeacher(id)
.map(teacher => course.teachers.push(teacher)));
}
return Observable.combineLatest(arrayOfObservables):
})
当应用处于后台时，此数据会显示firebase对手机的默认通知，但当应用处于前台时，系统会调用来自{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
的{{1}}方法。
使用数据有效负载
每次发送通知onMessageReceived方法都会被调用。因此，您可以根据需要构建通知。
