英文原文：http://tools.android.com/tips/lint

参照文章：/article/1697797.html
一、简介
AndroidLint是SDKTools16(ADT16)之后才引入的工具，通过它对Android工程源代码进行扫描和检查，可发现潜在的问题，以便程序员及早修正这个问题。AndroidLint提供了命令行方式执行，还可与IDE（如Eclipse）集成，并提供了html形式的输出报告。
由于AndroidLint在最初设计时就考虑到了independent于IDE,所以它可以很方便的与项目中的其他自动系统（配置/Build/测试等）集成.
AndroidLint主要用于检查以下这些错误：

1、Missingtranslations(andunusedtranslations)没有翻译的文本
2、Layoutperformanceproblems(alltheissuestheoldlayoutopttoolusedtofind,andmore)
3、Unusedresources未使用的冗余资源
4、Inconsistentarraysizes(whenarraysaredefinedinmultipleconfigurations)在多个配置中的数组大小不一致文件
5、Accessibilityandinternationalizationproblems(hardcodedstrings,missingcontentDescription,etc)
6、Iconproblems(likemissingdensities,duplicateicons,wrongsizes,etc)
7、Usabilityproblems(likenotspecifyinganinputtypeonatextfield)
8、Manifesterrors

当然AndroidLint远远不至检查以上的错误，更多的内容请参考《Android
Lint检查规则列表》

在Eclipse中可以在菜单Window->Preference->“LintEerrochecking”中设置规则的检查级别，如图1所示。
检查级别可以是:
Default
Fatal
Errro
Waring
Information
Ingore(即不检查)

图1



如果你只是想对lint的检查规则做些简单的定制，请参考《AndroidLint检查规则的定制（基本篇）》或英文官方文档
如果你想对lint的检查规则做些高级的定制，请参考官方文档Writing
NewLintChecksandWriting
CustomLintRules.
二、命令行中使用Lint
2.1、基本使用

在AndroidSDK的tools下有个叫lint.bat的文件，它就是lint的命令行工具。
lint命令后可以带一个或多个参数，参数之间用空格隔开，参数表示的是需要使用lint进行扫描的Android项目的目录。

2.2、DisablingChecks（--disable）
在执行lint命令时可以通过--disable选项要指定关闭的检查规则项。--disable选项后接要关闭的检查规则项的id（比如示例3中的MissingTranslation）或检查规则项的类别（比如示例3中的Usability:Icons和示例4的Internationalization）。
关于lint检查项的id和类别（Category）等信息请参考《Android
Lint检查规则列表》

2.3、enablingChecks(--enable和--check)
lint的有些检查项默认是关闭的(disable),在执行lint命令时可以通过--enable选项开启它。-enable选项后接要开启的检查规则项的id（比如示例5中的MissingTranslation）或检查规则项的类别（示例5中的Usability:Icons）
示例5
<pstyle="margin-top:0px;margin-bottom:10px;padding-top:0px;padding-bottom:0px;"><spanclass="pln">$lint</span><spanclass="pun"style="color:rgb(102,102,0);">--</span><spanclass="pln">disable</span><spanclass="typ"style="color:rgb(102,0,102);">MissingTranslation</span><spanclass="pun"style="color:rgb(102,102,0);">,</span><spanclass="typ"style="color:rgb(102,0,102);">UnusedIds</span><spanclass="pun"style="color:rgb(102,102,0);">,</span><spanclass="typ"style="color:rgb(102,0,102);">Usability</span><spanclass="pun"style="color:rgb(102,102,0);">:</span><spanclass="typ"style="color:rgb(102,0,102);">Icons</span><spanclass="pln"></span><spanclass="pun"style="color:rgb(102,102,0);">/</span><spanclass="pln">src</span><spanclass="pun"style="color:rgb(102,102,0);">/</span><spanclass="pln">astrid</span><spanclass="pun"style="color:rgb(102,102,0);">/</span></p>

在执行lint命令时可以通过--check选项来指定只进行某些检查。-check选项后接要开启的检查规则项的id（比如示例6中的MissingPrefix）
示例6
$lint--checkMissingPrefix/src/astrid/
2.4、检查项类别和检查项id
可以通过lint的--list选项来得到检查项类别和检查项id.
比如：
$
lint
--list


Validissuecategories:


Correctness


Security


Performance


Usability


Usability:Icons


Accessibility


Internationalization


Validissueid's:


"ContentDescription":EnsuresthatimagewidgetsprovideacontentDescription


"DuplicateIds":Checksforduplicateidswithinasinglelayout


"StateListReachable":Looksforunreachablestatesina<selector>


"InefficientWeight":LooksforinefficientweightdeclarationsinLinearLayouts


"ScrollViewSize":ChecksthatScrollViewsusewrap_contentinscrollingdimension


"MergeRootFrame":Checkswhetheraroot<FrameLayout>canbereplacedwitha<merge>tag


...


可以通过lint的--show选项后跟检查项id来得到一个检查项的详细说明.
比如：
$lint--showMissingPrefix


MissingPrefix


-------------


Summary:DetectXMLattributesnotusingtheAndroidnamespace


Priority:8/10


Severity:Warning


Category:Correctness


MostAndroidviewshaveattributesintheAndroidnamespace.When


referencingtheseattributesyou*must*includethenamespaceprefix,


oryourattributewillbeinterpretedbyaaptasjustacustom


attribute.

当然你也可以通过《Android
Lint检查规则列表》来查阅检查项的id等详细信息
2.4、html形式的report
在lint中，我们可以通过--html选项接文件路径的形式把代码扫描结果以html文件的形式进行输出。
示例6
<pstyle="margin-top:0px;margin-bottom:10px;padding-top:0px;padding-bottom:0px;"></p><div><spanclass="pln">C</span><spanclass="pun"style="color:rgb(102,102,0);">:</span><spanclass="pln">\Documents</span><spanclass="kwd"style="color:rgb(0,0,136);">and</span><spanclass="pln"></span><spanclass="typ"style="color:rgb(102,0,102);">Settings</span><spanclass="pln">\Administrator</span><spanclass="pun"style="color:rgb(102,102,0);">></span><spanclass="pln">lint</span><spanclass="pun"style="color:rgb(102,102,0);">--</span><spanclass="pln">htmlD</span><spanclass="pun"style="color:rgb(102,102,0);">:</span><spanclass="pln">\workspace\Test\report</span><spanclass="pun"style="color:rgb(102,102,0);">.</span><spanclass="pln">htm</span></div><div><spanclass="pln">lD</span><spanclass="pun"style="color:rgb(102,102,0);">:</span><spanclass="pln">\workspace\Test</span></div><div>

html输出报告如图2所示

Bydefault,linkstosourcefileswilljustuselocalfile://pathresources.YoucanremaptheURLstoadifferentprefixwiththe--urloption.
Forexample:

$lint--html/tmp/report.html--url/src/MyProj=http://buildserver/src/MyProj


2.5、命令行帮助
在lint中，你可以使用--help选项来得到lint命令的一些帮助信息。
示例7
lint--help
三、Eclispe中使用Lint
从ADT16开始，lint就集成到了ADT中。该它在lint命令行的基础上新增了以下功能

Automaticfixesformanywarnings自动修正大量警告

Lintgetsrunautomaticallyonvariouseditingoperations当编辑操作完成后，立即自动运行

Abilitytosuppresstypesoferrorsaswellasspecificinstancesofanerror可以suppress(忽略)一种类型的erro，也可以suppress(忽略)特定的一个erro

Abilitytoconfigureissueseverities能够配置issue（问题）的severities(严重性)

Jumpdirectlytotheproblemsourcefromthelintview通过lint视图能直接跳转到其问题对应的源码处

3.1、AutomaticLint
Lint将在以下情况下自动运行：

ExportanAPK.Inthiscaseitrunslintinaspecialmodewhichonlylooksforfatalerrors(whichisfaster)andabortstheexportifanyfatalerrorsarefound.YoucanturnoffthisintheLintOptions.在导出APK文件的时候，lint会做快速的扫描，以寻找fatal的错误。如果发现有fatal的错误，导出APK的操作将被迫终止

EditandSaveandXMLfile,suchasalayoutfileoramanifestfile.Inthiscase,allthefile-scopechecksthatapplytothegivenfilearerunandeditormarkersareaddedforanyissuesfound.编辑和保存XML文件，lint也会自动扫描这些文件。另外从ADT20开始，对于java源码文件在编辑和保存后，lint也会对他们进行扫描。
Usethelayouteditor.AftereveryUIoperation,file-scope
checks(suchasthevariouslayoutoptrules)arerunonthelayoutfileandtheresultsareshowninaspeciallintwindow(whichcanbeopenedfromtheerrormarkerwhichshowsinthetoprightcornerofthelayouteditorwhenerrorsarefound).对于使用layout
editor来操作布局文件时，在每个UI操作后,lint也会自动扫描该布局文件。

3.2、LintWindow
在Eclipse中，你可以通过两种方式来手动进行lint的扫描：
一种方式是通过工具栏，双击图3-1中红色箭头指向的按钮，然后出现图3-2所示的下拉框，在该下拉选择要进行lint扫描的工程
图3-1



图3-2



一种方式是选中一个Android工程，单击右键，在下拉菜单中选择“Androidtools”->"Runlint:checkcommonerro",如图3-3所示
图3-3
