在可展开通知中:图标应该有什么尺寸(以 dp 为单位)？ 喜欢这里的贪睡和电子邮件图标:
最佳答案
为了澄清这一点，我在 Android 支持库的 Javadoc 中找到了以下内容:
Add an action to this notification. Actions are typically displayed by the system as a button adjacent to the notification content.
Every action must have an icon (32dp square and matching the Holo Dark action bar visual style, a textual label, and a
PendingIntent.A notification in its expanded form can display up to 3 actions, from left to right in the order they were added. Actions will not be displayed when the notification is collapsed, however, so be sure that any essential functions may be accessed by the user in some other way.
因此，这些应该与您的操作栏图标(对于 Holo Dark 主题)相同，即:
Assets 大小:32dp x 32dp
光学正方形:24dp x 24dp
颜色(已启用):#FFFFFF 80% 不透明度
颜色(禁用):#FFFFFF 30% 不透明度
