我读启动图标的 UI准则但系统中的图标最近的Andr​​oid版本似乎并没有遵循这些准则（图标是平的，而不是简单的3D视角，如文件所述）。

I read the UI guidelines for Launcher icons but System Icons in recent Android releases doesn't seem to follow these guidelines (icons are flat instead simplified 3D perspective, as described in document).

他们是否已经过时了，什么是目前的指导方针？

Are they already obsolete and what are the current guidelines?

推荐答案

他们似乎并不因为Android 1.5版已经更新了指南，和Android 2.0 / 2.1的启动图标做不同的事情。我一直在有效地忽略了引导，当涉及到的图标自从Android 2.0的版本出来，但大多数的指南中的其他信息似乎仍然适用（通知，菜单图标等）。既然没有人反正强制执行的指导方针，这是更好地使您的应用程序适合近期和未来的Andr​​oid版本，而不是遵循三个主要的发布版的老过时的指导。

They don't seem to have updated the guide since the Android 1.5 release, and Android 2.0/2.1 do things differently for the Launcher icons. I've been effectively ignoring the guide when it comes to icons ever since the Android 2.0 release came out, though most of the other information in the guide seems to apply still (notifications, menu icons, etc.). Since no one enforces the guidelines anyways, it's better to make your app fit with the recent and future versions of Android than to follow the three-major-releases-old outdated guide.

他们还没有发布新的平板图标，任何规范或模板，但如果你做一个结帐大多数系统应用的图标在​​Android源$ C ​​$ C可作为参考使用（封装/应用/（应用程序名称）/ RES /绘，华电国际/ APP_（应用程序名称）巴纽，其中大多数）。

They haven't released any specs or templates for the new flat icons, but the icons for most of the system apps are available in the Android source code to use as reference if you do a checkout (packages/apps/(appname)/res/drawable-hdpi/app_(appname).png, for most of them).
