Android 8.0后Notification的创建方式

1. 基本通知方式

private void sendNotification(){
    int notificationId = 222;

    String channelId = "channel_name";

    String channelName = getPackageName();

    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);

    //创建NotificationChannel
    NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
    manager.createNotificationChannel(channel);

    Notification.Builder builder =new Notification.Builder(this, channelId);

    builder.setContentText("This is Content Text");

    builder.setContentTitle("This is title");

    builder.setChannelId(channelId);//创建通知时指定channelID

    builder.setColor(Color.GREEN);//SmallIcon color

    builder.setSmallIcon(R.drawable.ic_launcher_background);

    Notification notification = builder.build();

    manager.notify(notificationId, notification);
}
