The record

General train of thought

  • We’ll pass when we get a push messageNotificationManager.notify(int id, Notification notification)Send to the notification bar.
  • Log each notification bar message displayed and the correspondingid.
  • When entering the corresponding page according to product requirementsNotificationManager.cancel(id)Delete the corresponding notification message.

Pseudo code

Through the sendNotification (…). To display the push message, call similar to cleanMsgNotify(int Notice) on the corresponding interface to clear the push message.

public static final String CHANNEL_ID = "XXXX";
private static NotificationManager mNotificationManager;
private static List<PushMessageBean> notifyList;

public synchronized static void cleanMsgNotify(int notice) {
    if (mNotificationManager == null
            || notifyList == null || notifyList.size() == 0) {
        return;
    }
    for (int i = notifyList.size() - 1; i >= 0; i--) {
        PushMessageBean t = notifyList.get(i);
        if (t.notice == notice) {
            mNotificationManager.cancel(t.notifyId);
            notifyList.remove(i);
        }
    }
}
public void sendNotification(Context context, PushMessageBean message) {
    if (TextUtils.isEmpty(message.message)) {
        return;
    }
    NotificationCompat.Builder mBuilder;
    int notifyId = (int) System.currentTimeMillis();
    if (mNotificationManager == null) {
        mNotificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);
    }
    registerNotificationChannel();
    mBuilder = new NotificationCompat.Builder(context, CHANNEL_ID);
    mBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE)
            .setAutoCancel(true)
            .setContentText(message.message)
            .setSmallIcon(R.drawable.ic_launchers_round)
            .setVibrate(new long[]{1000})
            .setColor(context.getResources().getColor(R.color.color_primary))
            .setVisibility(Notification.VISIBILITY_PUBLIC)
            .setStyle(new NotificationCompat.BigTextStyle().bigText(message.message));
    if(build.version.sdk_int < build.version_codes.n) {// Title is not required above 7.0 mBuilder.setContentTitle(context.getResources().getString(R.string.app_name)); } message.notifyId = notifyId; saveNotification(message); mNotificationManager.notify(notifyId, mBuilder.build()); } private void saveNotification(PushMessageBean message) {if (notifyList == null) {
        notifyList = new ArrayList<>();
    }
    notifyList.add(message);
}
private void registerNotificationChannel() {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        NotificationChannel notificationChannel = mNotificationManager.getNotificationChannel(CHANNEL_ID);
        if (notificationChannel == null) {
            NotificationChannel channel = new NotificationChannel(CHANNEL_ID,
                    CHANNEL_ID, NotificationManager.IMPORTANCE_HIGH);
            channel.enableLights(true); // Whether to display channel.setlightColor (color.red) in the upper right corner of the desktop icon; //channel.
