Android8.0 Notification适配

Android8.0 Notification适配

1.新增的NotificationChannel

在Android8.0以后，发送通知都需要创建或者获取一个已有的通知通道NotificationChannel,这个通道可以定义通知的声音震动等类型，然后每个使用这个通道的通知都会具有这个类型的通知属性；

Demo
设置NotificationChannel:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    boolean isVibrateEnabled = MyApplication.getGeneralAlarmSettings()[1] == 1
    NotificationChannel notificationChannel = notificationManager.getNotificationChannel(NotificationUtils.NOTIFICATION_CHANNEL_ID);
    if (notificationChannel == null) {
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        notificationChannel = new NotificationChannel(NotificationUtils.NOTIFICATION_CHANNEL_ID, NotificationUtils.NOTIFICATION_CHANNEL_DESC, importance);
        notificationChannel.setLightColor(Color.GREEN);
        notificationChannel.enableVibration(isVibrateEnabled);
        notificationManager.createNotificationChannel(notificationChannel);
    }
}

这里需要给通道设置一个唯一的ID，以及描述。

2.创建一个通知

final Notification.Builder notificationBuilder = new Notification.Builder(MyApplication.getInstance(),NOTIFICATION_CHANNEL_ID);  notificationBuilder.setSmallIcon(R.drawable.ic_notification_logo);  notificationBuilder.setTicker(ticker);  notificationBuilder.setContentTitle(title);  notificationBuilder.setContentText(content);  
//设置Channel ID
notificationBuilder.setChannelId(NOTIFICATION_CHANNEL_ID);

//设置Channel
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    boolean isVibrateEnabled = MyApplication.getGeneralAlarmSettings()[1] == 1
    NotificationChannel notificationChannel = notificationManager.getNotificationChannel(NotificationUtils.NOTIFICATION_CHANNEL_ID);
    if (notificationChannel == null) {
        int importance = NotificationManager.IMPORTANCE_DEFAULT;
        notificationChannel = new NotificationChannel(NotificationUtils.NOTIFICATION_CHANNEL_ID, NotificationUtils.NOTIFICATION_CHANNEL_DESC, importance);
        notificationChannel.setLightColor(Color.GREEN);
        notificationChannel.enableVibration(isVibrateEnabled);
        notificationManager.createNotificationChannel(notificationChannel);
    }
}

notificationBuilder.setAutoCancel(true);  
Intent intent = new Intent(MyApplication.getInstance(), MainActivity.class);  
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);  
PendingIntent pendingIntent = PendingIntent.getActivity(MyApplication.getInstance(), 0 , intent, PendingIntent.FLAG_ONE_SHOT);  
notificationBuilder.setContentIntent(pendingIntent);  
notificationBuilder.setFullScreenIntent(pendingIntent, true);  
notificationManager.notify(alarmType.getValue(), notificationBuilder.build());

3.成功通知

通知发送成功之后，不同于之前版本的是发送通知的App右上角会有对应通知数量的小红点。
