很多项目都用到类似左侧滑动菜单的效果，比如facebook,evernote,VLC for android等等，这很酷

源代码可以从GitHub的https://github.com/jfeinstein10/slidingmenu上下载。

移植过程中会用到Actionbarsherlock这个项目，去http://actionbarsherlock.com/download.html下载。（两个下的都是最新版本）

步骤：

1.将下载的Actionbarssherlock中/library下的文件解压到workspace（你的项目目录）,改项目名称为Actionbarssherlock，从eclipse中操作new->project->Android
Project from Existing Code将项目添加进去，target改为api14以上。

2.将下载的slidingmenu中/library解压到workspace（你的项目目录），改名SlidingMenu，import该项目，右键->properties->android->api14以上。或者打开project.properties：target=Google
Inc.:Google APIs:14或更高，add
Actionbarssherlock为project library，邮件->properties->android->Libraty add...

3.这样SlidingMenu就可以用在自己项目中了。让我们来运行例子。解压slidingmenu中/example。import该项目，设置api14或更高，并add你的SlidingMenu为example的project
library。运行看看效果。2.1以上的系统都可以运行。

虽然是开源项目，但使用过程中还是可能会出现各种问题：

一、修复SlidingMenu library project里出现的错误

• Console error: Unable to resolve target ‘Google Inc.:Google APIs:16.

  Fix: 进入Properties检查Target
  sdk是否选择了 Google APIs.

• List of errors: ACTION_POINTER_INDEX_MASK cannot be resolved android.
  HONEYCOMB cannot be resolved or is not a field
  LAYER_TYPE_HARDWARE cannot be resolved or is not a field
  LAYER_TYPE_NONE cannot be resolved or is not a field
  MATCH_PARENT cannot be resolved or is not a field
  The method getLayerType() is undefined for the type View
  The method setLayerType(int, null) is undefined for the type View

  Fix: 将manifest里面的min
  sdk version 改为你当前用到的sdk版本，7以上.

二、修复example
project里出现的错误

• Console error: Found 2 versions of android-support-v4.jar in the dependency list,but not all the versions are identical (check is based
  on SHA-1 only at this time). Jar mismatch! Fix your dependencies

  Fix: 这是由于jar包版本不一致导致的，检查SlidingMenu和Actionbarsherlock中的\libs文件夹里的哪个android-support-v4.jar版本比较新，用新的替换掉其中的老版本.
  如果错误还是会出现，就clean项目并重启eclipse.

• List of errors: The method getSupportActionBar() is undefined for the type BaseActivity
  The method getSupportMenuInflater() is undefined for the type BaseActivity
  The method onCreateOptionsMenu(Menu) of type BaseActivity must override or implement a supertype method
  The method onOptionsItemSelected(MenuItem) in the type Activity is not applicable for the arguments
  The method onOptionsItemSelected(MenuItem) of type BaseActivity must override or implement a supertype method
  The method onOptionsItemSelected(MenuItem) of type ResponsiveUIActivity must override or implement a supertype method

  Fix:打开SlidingMenu
  library project里SlidingFragmentActivity这个类并在声明前添加以下代码:

  [java]
  view plaincopy

  1. import com.actionbarsherlock.app.SherlockFragmentActivity;  

  然后，将下面这个父类:

  [java]
  view plaincopy

  1. public class SlidingFragmentActivity extends FragmentActivity implements SlidingActivityBase {  

  换成Actionbarsherlock里的另外一个父类:

  [java]
  view plaincopy

  1. public class SlidingFragmentActivity extends SherlockFragmentActivity implements SlidingActivityBase {  

  如果错误还是会出现，就clean项目并重启eclipse.

  
  

  没错误以后运行出下面效果：
