如何在通知Android中创建天文台？

// 创建通知渠道
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    CharSequence channelName = "天文台";
    String channelId = "astronomy_channel";
    String channelDescription = "用于显示天文台相关通知";
    int importance = NotificationManager.IMPORTANCE_DEFAULT;
    NotificationChannel channel = new NotificationChannel(channelId, channelName, importance);
    channel.setDescription(channelDescription);
    NotificationManager notificationManager = getSystemService(NotificationManager.class);
    notificationManager.createNotificationChannel(channel);
}

// 构建通知内容
NotificationCompat.Builder builder = new NotificationCompat.Builder(this, "astronomy_channel")
        .setSmallIcon(R.drawable.notification_icon)
        .setContentTitle("天文台通知")
        .setContentText("观测到一颗新的恒星！")
        .setPriority(NotificationCompat.PRIORITY_DEFAULT);

// 设置通知行为
Intent intent = new Intent(this, MainActivity.class);
PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
builder.setContentIntent(pendingIntent);
builder.setAutoCancel(true);

// 发送通知
int notificationId = 1;
NotificationManagerCompat notificationManager = NotificationManagerCompat.from(this);
notificationManager.notify(notificationId, builder.build());
