从零开始学android<SlidingDrawer 隐式抽屉.三十三.>

SlidingDrawer是一种抽屉型的组件,当用户选择打开此抽屉之后,会得到一些可以使用的“程序集”,这样当一个界面要摆放多个组件的时候,使用此组件就可以很好的解决布局空间紧张的问题,SlidingDrawer类的定义如下所示:
ava.lang.Object
   ? android.view.View
     ? android.view.ViewGroup
       ? android.widget.SlidingDrawer

常用的方法
1
public void open()
普通
打开隐藏的抽屉
2
public void close()
普通
关闭隐藏的抽屉
3
public void lock()
普通
锁定“程序集”视图
4
public void unlock()
普通
解除锁定
5
public View getContent()
普通
得到所设置的“程序集”视图
6
public View getHandle()
普通
得到所设置的操作钮视图
7
public boolean isMoving()
普通

8
public boolean isOpened()
普通
是否打开
9
public void setOnDrawerOpenListener(
SlidingDrawer.OnDrawerOpenListener onDrawerOpenListener)
普通
打开抽屉组件时触发事件
10
public void setOnDrawerCloseListener(
SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener)
普通
关闭抽屉组件时触发事件
11
public void setOnDrawerScrollListener(
SlidingDrawer.OnDrawerScrollListener onDrawerScrollListener)
普通
移抽屉组件时触发事件
