SlidingDrawer隐藏屏外的内容,并允许用户通过handle以显示隐藏内容。它可以垂直或水平滑动,它有俩个View组成,其一是可以拖动的handle,其二是隐藏内容的View.它里面的控件必须设置布局,在布局文件中必须指定handle(手柄)和content.
二、重要属性
android:allowSingleTap:指示是否可以通过handle打开或关闭
android:animateOnClick:指示是否当使用者按下手柄打开/关闭时是否该有一个动画。
android:content:隐藏的内容
android:handle:handle(手柄)
三、重要方法
animateClose():关闭时实现动画。
close():即时关闭
getContent():获取内容
isMoving():指示SlidingDrawer是否在移动。
isOpened():指示SlidingDrawer是否已全部打开
lock():屏蔽触摸事件。
setOnDrawerCloseListener(SlidingDrawer.OnDrawerCloseListener onDrawerCloseListener):SlidingDrawer关闭时调用
setOnDrawerOpenListener(SlidingDrawer.OnDrawerOpenListener onDrawerOpenListener):SlidingDrawer打开时调用
unlock():解除屏蔽触摸事件。
toggle():切换打开和关闭的抽屉SlidingDrawer。
