Icon Templates Pack »（Android图标模版）
Creating a unified look and feel throughout a user
interface adds value to your product. Streamlining the graphic style will also
make the UI seem more professional to the user.（创建具有统一的视觉效果的用户界面会为你的产品增色不少。图像风格的合理性能让UI设计更加专业。）
This document shows you how to create icons for various
parts of your application’s user interface that fit the style set by the
Android UI team. Following these guidelines will help you to create a polished
and unified experience for the user.（该文档向你展示如何为你的应用的UI创建各种图表，并让它适合Android UI组图标的风格。依照这些规范能帮助你，为你的用户创建具有更加优秀和统一风格的体验。）
To get started creating conforming icons more quickly,
you can download the Android Icon Templates Pack. For more information, see Using the Android Icon Template
Pack.（为了能更快让你能创建统一风格的图标，你可以先下载Android图标模版。更多信息，请参阅’Using the Android
Icon Template Pack’）
Launcher icon
启动图标
A launcher icon is the graphic that represents your
application on an Android device’s Home screen. It is a simplified 3D icon with
a fixed perspective. The required perspective is shown in Figure 1.（启动图标是指在Android机器主屏幕上为你的应用准备的图标。它是一个简单的具有固定视角的3D图标。透视信息需求请参见图1）
Structure
结构
·
The base
of a launcher icon can face either the top view or the front view.（启动图标的基面可以朝上也可以朝前）
·
The
majority of a launcher icon’s surface should be created using the launcher icon color palette. To
add emphasis, use one or more bright accent colors to highlight specific
characteristics.（创建启动图标表面的时候需要使用启动图标色板。强调一下，使用一种或者更多重点色来高亮特性。）
·
All
launcher icons must be created with rounded corners to make them look friendly
and simple—as shown in Figure 2.（所有的启动图标必须是圆角的，让它看起来更加友好、简单——如图2）
·
All
dimensions specified are based on a 250x250 pixel artboard size in a vector
graphics editor like Adobe Illustrator, where the icon fits within the artboard
boundaries.（所有的维数规范是基于250x250像素大小的一个图像矩阵编辑器，比如Adobe Illustrator, 图标能适合剪辑版的边缘。）
·
Final art must be scaled down and exported as a transparent 48x48 px PNG
file using a raster image editor such as Adobe Photoshop.（最终的图标需要重定义大小，导出图标要求是：透明 48x48 px, png 文件，可以使用光栅图像编辑器，比如Adobe Photoshop）
·
Templates
for creating launcher icons in Adobe Illustrator and Photoshop are available in
the Icon Templates Pack.（使用Adobe Illustrator 和Photoshop创建启动图标的模版，可以在图标模版包中找到。）
Light, effects, and
shadows（光照，效果，和阴影）
Launcher icons are simplified 3D icons using light and
shadows for definition. A light source is placed slightly to the left in front
of the icon, and therefore the shadow expands to the right and back.（启动图标是使用简单的带定义的光照和阴影效果的3D图标。光源被放置在稍微偏左前方位置，因此阴影投向右后方。）
Menu icon菜单图标
Menu icons are graphical elements placed in the pop-up
menu shown to users when they press the Menu button. They are drawn in a
flat-front perspective. Elements in a menu icon must not be visualized in 3D or
perspective（菜单图标，用户在点击菜单按钮时具有弹出菜单效果的图像元件。图标使用平面绘制前透视图。菜单图标不可以使用3D效果或者透视。）.
Structure 结构
·
In order
to maintain consistency, all menu icons must use the same primary palette and
the same effects. For more information, see the menu icon color palette.（为了保持一致性，所有的菜单图标都必须使用一样的主调色板和一样的效果。更多信息，请参见 菜单图标调色板）
·
Menu
icons should include rounded corners, but only when logically appropriate. For
example, in Figure 3 the logical place for rounded corners is the roof and not
the rest of the building.(菜单图标应该是圆角的，但是也只有逻辑上允许的时候。比如图3中逻辑上的圆角位置应该是屋顶而不是这个建筑的其他地方。)
·
All
dimensions specified on this page are based on a 48x48 pixel artboard size with
a 6 pixel safeframe.（页面上所有的尺寸规格都是基于48x48 px 并包含6px的安全边框区域。）
·
The menu
icon effect (the outer glow) described in Light, effects, and shadows can overlap the 6px safeframe, but only when necessary.
The base shape must always stay inside the safeframe.（在光照、效果和阴影一节中所描述的菜单图标效果（外边缘）在必要的时候可以超过6px的安全框架。基础形状部分必须在安全框架之内。）
·
Final art must be exported as a transparent PNG file.（最后的图片导出必须是透明的PNG 文件）

and some other effects, which are shown below, are used to create depth.
菜单图标是平面的面朝上的。轻微的凹陷效果或者其他效果被用来体现层次感。
Status bar icon（状态栏图标）
Status bar icons are used to represent notifications from
your application in the status bar. Graphically, they are very similar to menu
icons, but are smaller and higher in contrast.（状态栏图标是用来在状态栏中向用户像是应用通知。在图像方面来讲，他们跟菜单图标很像，但是更小，并具有更高的对比度。）

Unselected
tab icons have the same fill gradient and effects as menu icons, but with no
outer glow.（未选中标签图标和菜单图标有一样的填充斜度和效果，但是没有外发光。）
·
Selected
tab icons look just like unselected tab icons, but with a fainter inner shadow,
and have the same front part gradient as dialog icons.（选中标签图标看起来和未选中的标签图标很像，但是会有微弱的内部阴影，同时又有和对话框图标一样的前部斜度。）
·
Tab
icons have a 1 px safeframe which should only be overlapped for the edge of the
anti-alias of a round shape.（标签图标正常带1像素的安全边框，但是在安全边框区域是要能够反锯齿的圆角形状是可以的）

effects as the menu icon, but with no outer glow.
选中标签图标与菜单图标具有相同的填充色度和效果，但是没有外发光。
Dialog icon（对话框图标）
Dialog icons are shown in pop-up dialog boxes that prompt
the user for interaction. They use a light gradient and inner shadow in order
to stand out against a dark background.
对话框图标在弹出对话框中显示，提示用户进行交互。为了能再暗色背景上突出显示，它使用微倾斜和内部阴影。
Structure（结构）
·
Dialog
icons have a 1 pixel safeframe. The base shape must fit within the safeframe,
but the anti-alias of a round shape can overlap the safeframe.（对话框图标正常带1像素的安全边框，但是在安全边框区域是要能够反锯齿的圆角形状是可以的）

stand out against a dark background, they are built up using a light gradient
and inner shadow.（对话框图标是平面的，并且图片面朝上的。为了能在暗色背景中显得更加明显，在它们建立的时候使用光照梯度和内部阴影。）
List view icon（列表视图图标）
List view icons look a lot like dialog icons, but they
use an inner shadow effect where the light source is above the object. They are
also designed to be used only in a list view. Examples include the Android
Market application home screen and the driving directions screen in the Maps
application.
列表视图图标很像对话框图标，但是他们使用光源在物体上方的内部阴影效果。他们也被设计成只在列表视图中使用。图例包括Android Market 应用程序主界面和地图应用中的驾车导航界面。

General guidelines(通用规则)
Below are some "do and don't" guidelines to
consider when creating icons for your application. By following the guidelines,
you can ensure that your icons will work well with other parts of the Android
platform UI and will meet the expectations of your application's users.
下面是创建应用图标的时候一些“可以”和“不可以”的规定。通过遵循这些规定，可以保证你的图标能很好的在Android 平台的UI上和其他部分结合并达到你的用户群的需求。
Using the Android Icon Templates Pack（使用Android图标模版包）
The Android Icon Templates Pack is a collection of
template designs, filters, and settings that make it easier for you to create
icons that conform to the general specifications given in this document. We recommend
downloading the template pack archive before you get started with your icon
design.
Android图标模版库包括模版设计、滤镜和一些怎样让你方便的设计符合通用规则的图标。我们建议你在开始你的图标设计之前下载这个模版包文档。
The icon templates are provided in Adobe Photoshop and
Adobe Illustrator file formats, which preserves the layers and design
treatments we used when creating the standard icons for the Android platform.
You can load the template files into any compatible image-editing program,
although your ability to work directly with the layers and treatments may vary
based on the program you are using.
图标模版支持Photoshop和Illustrator文件格式，并保留了一些我们为Android平台创建图标时候的层信息。你可以加载这些文件到任何可兼容的图像编辑程序，因为你可能对自己正在用的这些应用程序工具有比较好的了解。
You can obtain the Icon Templates Pack archive using the

Standard launcher
icons（标准的启动图标）
Shown below are examples of launcher icons used by
Android applications. The icons are provided for your reference only — please
do not reuse these icons in your applications..以下是Android应用程序的启动图标样例。仅供参考，请不要再你的应用中使用这些图标。
Standard menu icons （标准的菜单图标）
Shown below are standard menu icons that are included in
the Android platform (as of Android 1.5). You can reference any of these icon
resources from your application as needed, but make sure that the action you
assign to the icon is consistent with that listed. Note that this is not a
complete list of icons and that the actual appearance of standard icons may
change across platform versions.以下是Android平台（比如Android 1.5）包含的标准的菜单图标。你可以在你的应用中引用任意一个图标资源，但是必须确保你分配的是相应的列表中的资源。注意这不是一个完整的图标列表，图标的外形可能在不同平台版本中变得不一样。
To reference one of the icons from your code, use android.R.drawable.<icon_resource_identifier>. For example, you can call a menu item's setIcon() method and pass the resource name:
在你的代码中引用一个图标：
使用
android.R.drawable.<icon_resource_identifier>. 比如，你能调用一个菜单单位的
setIcon() 方法传递资源的名称：
.setIcon(android.R.drawable.ic_menu_more);.
You could reference the same icon from a layout file
using android:icon="@android:drawable/ic_menu_more">.
你可以在图层文件中引用同一个图标：使用
android:icon=”@android:drawable/ic_menu_more”>
To determine the resource ID for an icon listed below,
hover over the icon or simply look at image filenames, which use the format
"<icon_resource_identifier>.png".
判断如下列表中的图标资源ID，查看图标或者通过简单查看图片文件名称（命名规则是“图标_资源_标识.png”）
Standard status bar
icons（标准的状态栏图标）
Shown below are standard status bar icons included in the
Android platform (as of Android 1.5). You can reference any of these icon
resources from your application as needed, but make sure that the meaning of
the icon is consistent with the standard meaning listed. Note that this is not
a complete list of icons and that the actual appearance of standard icons may
change across platform versions.
以下是Android平台（比如Android 1.5）包含的标准的状态栏图标。你可以在你的应用中引用任意一个图标资源，但是必须确保你分配的是相应的列表中的资源。注意这不是一个完整的图标列表，图标的外形可能在不同平台版本中变得不一样。
To reference one of the icons from your code, use android.R.drawable.<icon_resource_identifier>. For example, you can construct a simple
notification that references one of the icons like this:
在你的代码中引用一个图标：
使用android.R.drawable.<icon_resource_identifier>.
比如，为了构建一个简单的通知，我们这样引用一个图标：
new
Notification(R.drawable.stat_notify_calendar, "sample text",
System.currentTimeMillis());
To determine the resource ID for an icon listed below, hover
over the icon or simply look at the image filename, which use the format
"<icon_resource_identifier>.png".
判断如下列表中的图标资源ID，查看图标或者通过简单查看图片文件名称（命名规则是“图标_资源_标识.png”）

Light, effects, and
shadows（光照、效果和阴影）
Unselected tab icons look just like the selected tab
icons, but with a fainter inner shadow, and the same front part gradient as the
dialog icons.（未选中标签图标看起来和选中图标很像，不同的是微带内部阴影，前部填充色与对话框图标相同。）

| Step by step（步骤） 1. Create the basic shapes using a tool like Adobe Illustrator.( 使用Illustrator创建基本图形) ) 2. Import the shape to a tool like Adobe Photoshop and scale to fit an image of 32x32 px on a transparent background.(将图形导入到photoshop中，调整成32x32px，透明背景) 3. Add the effects seen in Figure 10 for the unselected state filter.（增加图10中所描述的滤镜效果） 4. Export the icon at 32x32 as a PNG file with transparency enabled.（导出32x32大小的透明png图标文件） |
The selected tab icons have the same fill gradient and
effects as the menu icon, but with no outer glow.
选中标签图标与菜单图标具有相同的填充色度和效果，但是没有外发光。

Dialog icons are shown in pop-up dialog boxes that prompt
the user for interaction. They use a light gradient and inner shadow in order
to stand out against a dark background.
对话框图标在弹出对话框中显示，提示用户进行交互。为了能再暗色背景上突出显示，它使用微倾斜和内部阴影。

shadows(光照、效果和阴影)
Dialog icons are flat and pictured face-on. In order to
stand out against a dark background, they are built up using a light gradient
and inner shadow.（对话框图标是平面的，并且图片面朝上的。为了能在暗色背景中显得更加明显，在它们建立的时候使用光照梯度和内部阴影。）

List view icons look a lot like dialog icons, but they
use an inner shadow effect where the light source is above the object. They are
also designed to be used only in a list view. Examples include the Android
Market application home screen and the driving directions screen in the Maps
application.
列表视图图标很像对话框图标，但是他们使用光源在物体上方的内部阴影效果。他们也被设计成只在列表视图中使用。图例包括Android Market 应用程序主界面和地图应用中的驾车导航界面。

Below are some "do and don't" guidelines to
consider when creating icons for your application. By following the guidelines,
you can ensure that your icons will work well with other parts of the Android
platform UI and will meet the expectations of your application's users.
下面是创建应用图标的时候一些“可以”和“不可以”的规定。通过遵循这些规定，可以保证你的图标能很好的在Android 平台的UI上和其他部分结合并达到你的用户群的需求。
| Do...可以 · Use a normal perspective. The depth of an object should be realistic. · 使用正常的透视角。元件的深度应该比较真实。 · Keep it simple! By overdoing an icon, it loses it purpose and readability. · 保持简单！重复的修改一个图标会让图标失去意义和真实性。 · Use colors only when necessary. Mind that the base of a launcher icon should be grey and feel solid.在必要的时候使用色彩。注意启动图标应该是灰色并固体填充的。 · Use the correct angles for the specific icon types.使用正确的规格类型的角度。 | Don’t...不可以 · Use open elements like text alone as icons. Instead place those elements on a base shape. · Use colors for your status bar notifications. Those are reserved for specific phone-only functions. · 使用类似单独文本作为开放元件图标，而不是使用基础图形。 · 为你的状态栏通知使用颜色。这些都是为手机功能预留的。 |

The Android Icon Templates Pack is a collection of
template designs, filters, and settings that make it easier for you to create
icons that conform to the general specifications given in this document. We recommend
downloading the template pack archive before you get started with your icon
design.
Android图标模版库包括模版设计、滤镜和一些怎样让你方便的设计符合通用规则的图标。我们建议你在开始你的图标设计之前下载这个模版包文档。
The icon templates are provided in Adobe Photoshop and
Adobe Illustrator file formats, which preserves the layers and design
treatments we used when creating the standard icons for the Android platform.
You can load the template files into any compatible image-editing program,
although your ability to work directly with the layers and treatments may vary
based on the program you are using.
图标模版支持Photoshop和Illustrator文件格式，并保留了一些我们为Android平台创建图标时候的层信息。你可以加载这些文件到任何可兼容的图像编辑程序，因为你可能对自己正在用的这些应用程序工具有比较好的了解。
You can obtain the Icon Templates Pack archive using the
link below:你可以使用下面的链接下载图标模版库

Icon appendix（图标附录）
Standard launcher
icons（标准的启动图标）
Shown below are examples of launcher icons used by
Android applications. The icons are provided for your reference only — please
do not reuse these icons in your applications..以下是Android应用程序的启动图标样例。仅供参考，请不要再你的应用中使用这些图标。
 Alarm Clock | Browser | Calculator | Calendar | Camcorder | Camera | Contacts |
Dialer | | Gallery | Generic application | Gmail | Google Talk | IM |
Maps | Market | Messaging | Music | Settings | Voice Dialer | Voice Search |
YouTube |
Shown below are standard menu icons that are included in
the Android platform (as of Android 1.5). You can reference any of these icon
resources from your application as needed, but make sure that the action you
assign to the icon is consistent with that listed. Note that this is not a
complete list of icons and that the actual appearance of standard icons may
change across platform versions.以下是Android平台（比如Android 1.5）包含的标准的菜单图标。你可以在你的应用中引用任意一个图标资源，但是必须确保你分配的是相应的列表中的资源。注意这不是一个完整的图标列表，图标的外形可能在不同平台版本中变得不一样。
To reference one of the icons from your code, use android.R.drawable.<icon_resource_identifier>. For example, you can call a menu item's setIcon() method and pass the resource name:
在你的代码中引用一个图标：
使用
android.R.drawable.<icon_resource_identifier>. 比如，你能调用一个菜单单位的
setIcon() 方法传递资源的名称：
.setIcon(android.R.drawable.ic_menu_more);.
You could reference the same icon from a layout file
using android:icon="@android:drawable/ic_menu_more">.
你可以在图层文件中引用同一个图标：使用
android:icon=”@android:drawable/ic_menu_more”>
To determine the resource ID for an icon listed below,
hover over the icon or simply look at image filenames, which use the format
"<icon_resource_identifier>.png".
判断如下列表中的图标资源ID，查看图标或者通过简单查看图片文件名称（命名规则是“图标_资源_标识.png”）
 Add |  Call |  Camera |  Clear / Close / Cancel / Discard |  Compass |  Delete |  Directions |
 Edit |  Gallery |  Help |  Info / details |  Map mode |  My Location |  More |
 Preferences |  Rotate |  Save |  Send |  Search |  Share |  Upload |
 View |  Zoom |
icons（标准的状态栏图标）
Shown below are standard status bar icons included in the
Android platform (as of Android 1.5). You can reference any of these icon
resources from your application as needed, but make sure that the meaning of
the icon is consistent with the standard meaning listed. Note that this is not
a complete list of icons and that the actual appearance of standard icons may
change across platform versions.
以下是Android平台（比如Android 1.5）包含的标准的状态栏图标。你可以在你的应用中引用任意一个图标资源，但是必须确保你分配的是相应的列表中的资源。注意这不是一个完整的图标列表，图标的外形可能在不同平台版本中变得不一样。
To reference one of the icons from your code, use android.R.drawable.<icon_resource_identifier>. For example, you can construct a simple
notification that references one of the icons like this:
在你的代码中引用一个图标：
使用android.R.drawable.<icon_resource_identifier>.
比如，为了构建一个简单的通知，我们这样引用一个图标：
new
Notification(R.drawable.stat_notify_calendar, "sample text",
System.currentTimeMillis());
To determine the resource ID for an icon listed below, hover
over the icon or simply look at the image filename, which use the format
"<icon_resource_identifier>.png".
判断如下列表中的图标资源ID，查看图标或者通过简单查看图片文件名称（命名规则是“图标_资源_标识.png”）
