Android基础：SlidingDrawer知识
SlidingDrawer抽屉，主要有handler和content组成，handler一般是图片，cotent随意，基本的方法主要有
open()、animateOpen()、close()、animateClose()、SlidingDrawer.setOnDrawerOpenListener()、SlidingDrawer.setOnDrawerCloseListener()
lock()、unlock(), 系统自带的抽屉可以从下往上、或者从右往左拉开，通过orientation来设置，如果要使SlidingDrawer按指定高度拉开，应该放到Relativelayout中，同时设置alignParentBotom为true.
