Question

我在为android 8.0及更高版本创建通知时遇到问题此代码正确吗？请看一下频道创建。

private void createNotificationChannel() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            String name = getString(R.string.channel_name);
            String description = getString(R.string.channel_description);
            int importance = NotificationManager.IMPORTANCE_HIGH; //Important for heads-up notification
            NotificationChannel channel = new NotificationChannel("0", name, importance);
            channel.setDescription(description);
            channel.setShowBadge(true);
            channel.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
            NotificationManager notificationManager = getSystemService(NotificationManager.class);
            notificationManager.createNotificationChannel(channel);
        }
        res = getIntent().getStringExtra("Reminder");
        Notification.Builder mBuilder = new Notification.Builder(ReminderfabActivity.this);
        mBuilder.setSmallIcon(R.drawable.ic_assignment_late_black);
        mBuilder.setContentTitle("Alert!");
        mBuilder.setContentText(res);
        mBuilder.setDefaults(Notification.DEFAULT_SOUND | Notification.DEFAULT_VIBRATE);

        NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);

        Intent notificationIntent = new Intent(getApplicationContext(), MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK);

        mBuilder.setContentIntent(pendingIntent).setAutoCancel(false);
        notificationManager.notify(0, mBuilder.build());
    }

您应该使用NotificationCompat.Builder而不是Notification.Builder

更改此行Notification.Builder mBuilder = new Notification.Builder(ReminderfabActivity.this);

到

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(ReminderfabActivity.this,"0");

，并更改此行PendingIntent pendingIntent = PendingIntent.getActivity(getApplicationContext(), 0, notificationIntent, Intent.FLAG_ACTIVITY_NEW_TASK); 您应该使用PendingIntent中的标志之一，而不是intent

中的标志
