Android: 仿Launcher Workspace左右滑动控件

Android: 仿Launcher Workspace左右滑动控件

修改Launcher的Workspace，去掉Drag相关的操作，精简为一个支持左右滑动的控件

每屏中可以自由放置layout

主要的问题是对

    @Override
    public boolean dispathTouchEvent(MotionEvent ev) {}

    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {}

    @Override
    public boolean onTouchEvent(MotionEvent ev) {}

的理解，不然不好控制touch事件

代码贴上，其实没啥参考价值:
