因為項目中用到第三級菜單，我們原有的界面框架已經不適用于該項目，Android L出了新的cardview設計，爬了下github發現有些高手已經把card整合為更方便調用的類庫了，我這個項目就準備試用一下其中的一個開源項目cardslib ? ? ?， 而github我也是初次使用，正好在項目中來熟悉使用方法

首先：

　　cardslib項目地址：https://github.com/gabrielemariotti/cardslib，意大利的一位java/android工程師gabrielemariotti，基于Android L 的cardview做的一個便于引用和擴展的卡片式布局，可以fork一下到自己的代碼倉庫。

　　我的項目中主要用到其中的library-core和library-cards，以下為作者提供的eclipse中引入該項目為類庫的方法（不得不說國外開發牛實在是太貼心了T_T，文檔寫得盡善盡美，我這種初級菜鳥也能按部就班的實現）：

Reference this project as a library in Eclipse

If you would like to use this?library-core?in Eclipse you have to do these steps:

• clone a copy of this repository, or download it (outside eclipse workspace)
• import the code in your workspace starting from library folder. The Wizard will import the code in library-core/src/main. I suggest you naming it "cardscore" (or another name) instead of "main".
• mark java(*) folder as source (click on folder -> Build-Path -> use as source folder). You can also remove the src folder, from the project.
• mark cardscore as Android Library (Properties -> Android -> Is library)
• add support library v4 rel.21
• add support cardview library v7 rel.21
• add support annotation library rel.21
• The library targets SDK 21 and works with minSdk=14. In any cases you need to use API>=21 to compile library (Properties -> Android)
• Clean and build

If you would like to use this?library-cards?in Eclipse you have to do these steps:

• clone a copy of this repository, or download it (outside eclipse workspace)
• import the code in your workspace starting from library folder. The Wizard will import the code in library-cards/src/main. I suggest you naming it "cardscore" (or another name) instead of "main".
• mark java(*) folder as source (click on folder -> Build-Path -> use as source folder). You can also remove the src folder, from the project.
• mark cardscore as Android Library (Properties -> Android -> Is library)
• add the cardscore as library
• The library targets SDK 21 and works with minSdk=14. In any cases you need to use API>=21 to compile library (Properties -> Android)
• Clean and build

注意要點：

1、需要anroid 21的SDK支持

2、把引用代碼的main文件夾重命名，并右鍵build-path該文件夾為"use as source folder"，否則可能會造成代碼沖突

3、將工程作為Android Libaray，引入相應support ?library

引用后，在build時和編譯時分別出過一個問題：

1、build后，報錯，Found 4 versions of android-support-v4.jar in the dependency list

查看了報錯信息是因為之前引用的滑動菜單的幾個library中，android-support-v4的版本和cardslib中所用版本不同。拷cardslib中的v4過去就行了

2、運行時報錯，2 Output: UNEXPECTED TOP-LEVEL EXCEPTION: com.android.dex.DexException: Multiple dex files?define?Landroid/support/annotation/AnimRes;

?應該是導入的包和以前的導入有沖突，解決辦法簡單粗暴：我把我的項目中libs文件夾下的包全部拷出來，然后重建這個文件夾，手動一個個拷進去檢查，直到0 error為止（可能有些運行時要用的包沒有拷到，以后運行時報錯的時候再根據提示單獨拷就可以了：）最后在stackoverflow找到原因，引用的library-core庫中，新版本的support-v4包已經包含了support-annotations的內容，刪去annotations包即可：

The problem is that?android-support-annotations.jar?used to be a separate library containing the android annotations, but for some reason these annotations are already included in recent versions of the?android-support-v4.jar?file.
