NotificationChannel 名称和描述的目的

问题描述

在Android中设置通知时，从Oreo开始，还需要设置一个NotificationChannel

为了设置它，你需要给它一个 name: String 和一个 description: String 这是可选的.

val name = "测试通道"val description = "测试描述"val 重要性 = NotificationManager.IMPORTANCE_DEFAULTval channel = NotificationChannel("ID", 名称, 重要性)频道.描述 = 描述

根据文档，我无法弄清楚为什么您需要输入这两个值，它们不会出现在 UI 中，即使在新的 Android P 测试版中也不会显示.

创建 NotificationChannel 时使用的名称和描述是什么?

正如前两个答案所表明的那样，我在询问时可能不清楚.我知道 NotificationChannel 是干什么用的，我不清楚 name 和 description 属性是干什么用的.

解决方案

• NotificationChannel 使我们的应用程序开发人员能够将我们的通知分组到组频道中，用户可以一次修改整个频道的通知设置
• 通知渠道允许我们将通知分成不同的组/类别.每个通道都有一个共同的功能.它允许用户自定义他们的通知设置.

用户可以从应用设置中执行以下操作:

1. 阻止来自特定频道的通知.

2. 在不同的通知渠道上设置优先级/静音.

NotificationChannel 名称的用途

NotificationChannel 名称用于在系统设置中显示 NotificationChannel

setName() 用于设置一个 NotificationChannel 的名称setName() 设置 NotificationChannel 的用户可见名称.

推荐的最大长度为 40 个字符；如果太长，该值可能会被截断.

NotificationChannel 描述的目的

NotificationChannel 说明

设置 NotificationChannel 的用户可见描述.

指定用户在系统设置中看到的描述

When setting up notification in Android, starting from Oreo, you need to setup also a NotificationChannel

In order to set it up you need to give it a name: String and a description: String which is optional.

val name = "test channel"
val description = "test description"
val importance = NotificationManager.IMPORTANCE_DEFAULT

val channel = NotificationChannel("ID", name, importance)
channel.description = description

I couldn't figure out as per the documentation why you need to enter this two values, They don't seam to show up in the UI, not even in the new Android P betas.

What are name and description used for when creating a NotificationChannel?

EDIT:

As evinced by the first two answers, I probably wasn't clear when asking. I know what NotificationChannel is for, It's not clear to me what the name and description attributes are for.

解决方案

• NotificationChannel enable us app developers to group our notifications into groups channels with the user having the ability to modify notification settings for the entire channel at once
• Notification Channels allow us to separate notifications into different groups/categories. Every channel would have a common functionality. It allows the user to customize their notification settings.

Feature the user can do the following things from the Apps Settings:

1. Block notifications from a particular channel.

2. Set priority/silent on different notification channels.

the NotificationChannel name is use for displaying NotificationChannel in system setting

setName() is used to set the name of a NotificationChannel setName() Sets the user visible name of a NotificationChannel.

The recommended maximum length is 40 characters; the value may be truncated if it is too long.

NotificationChannel Description

Sets the user visible description of a NotificationChannel.

specify the description that the user sees in the system settings
