当应用程序在后台时，如何以收件箱样式添加 fcm 通知？
当我添加以下代码时，我在打开应用程序时得到收件箱样式
但如果应用程序是后台的，它会显示单独的通知
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
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"notification" : {
"body" : "great match!",
"title" : "Portugal vs. Denmark",
"icon" : "myicon"
}
}
当应用处于后台时，此数据将显示 Firebase 向手机发送的默认通知，但当应用处于前台时，将调用 FirebaseMessagingService Firebase 向手机发送onMessageReceived方法。
使用数据有效负载
每次发送通知时onMessageReceived都会调用该方法。因此，您可以根据需要构建通知。
{
"to" : "bk3RNwTe3H0:CI2k_HHwgIpoDKCIZvvDMExUdFQ3P1...",
"data" : {
"Nick" : "Mario",
"body" : "great match!",
"Room" : "PortugalVSDenmark"
},
}

有两种类型的 FCM 消息。
- 通知消息。
- 数据消息。
FCM
发送数据消息，然后它将出现在您的调用方法中。
当应用程序在后台时，FCM 不调用 onMessageReceived 方法。而不是显示默认通知。
