侧滑菜单之DragLayout初识

1、使用时的特点：用DragLayout嵌套内容页和菜单部分的所有内容将DragLayout作为布局文件的跟标签

2、 在DragLayout的标签之间添加2个子标签

        第一个必须为RelativeLayout,用于封装菜单部分的显示

        第二个必须为框架中自定义的MyRelativeLayout，用于封装内容部分的显示

3、代码中获取DragLayout对象

4、过DragLayout对象设置监听事件DragListener

5、可以DragListener的监听中更改内容页图标的透明度等变化

如需通过代码控制菜单的打开和关闭：

dl.open(true); //打开菜单，参数代表打开过程中有动画效果

dl.close();  // 关闭菜单

注意：

1、必须对dragLayout设置背景，否则会出现空指针异常

2、必须对dragLayout设置setDragListener，如果不设置，内容没有缩放效果

3、菜单和内容共用一个标题栏

功能：

1、效果新颖

2、添加动画效果，对拉动能够监听

3、滑动可以通过内容进行控制，不需要从边缘
