记录一下

大致思路

我们收到推送消息的时候会通过 NotificationManager.notify(int id, Notification notification) 发送到通知栏。
记录每一个显示的通知栏消息和对应的 id.
按产品要求在进入对应的页面的时候通过 NotificationManager.cancel(id) 删除对应的通知栏消息。

伪代码

通过sendNotification(...)显示推送消息，在对应的界面调用类似 cleanMsgNotify(int notice) 清除推送消息即可。

public static final String CHANNEL_ID = "XXXX";private static NotificationManager mNotificationManager;private static List 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) {//7.0以上不需要title        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); //是否在桌面icon右上角展示小红点            channel.setLightColor(Color.RED); //小红点颜色            //channel.setShowBadge(true); //是否在久按桌面图标时显示此渠道的通知            mNotificationManager.createNotificationChannel(channel);        }    }}
