##一个协调布局的行为库
###ScrollBehavior支持属性
| scroll_orientation 跟随滚动目标的滚动方向 |
|---|
| horizontal_same 目标水平滚动跟随它的方向 |
| horizontal_reverse 目标水平滚动跟随它的反方向 |
| vertical_same 目标垂直滚动跟随它的方向 |
| vertical_reverse 目标垂直滚动跟随它的反方向 |
enable_alpha 是否开启滚动透明度渐变
enable_scale 是否开启滚动缩放渐变
enable_translate 是否开启滚动位移渐变
enable_smooth_fling 是否开启惯性滚动时顺滑滚动
damping 0~1，目标滑动距离*damping，类似阻尼
fling_anim_duration 若开启惯性滚动时顺滑滚动，可以设置此动画时长
dependence_id 依赖的目标id，用于决定跟随哪个View滚动
| dependence_scroll_orientation 依赖的滚动目标的滚动方向 |
|---|
| horizontal_same 依赖的目标水平滚动方向 |
| horizontal_reverse 依赖的目标水平滚动方向 |
| vertical_same 依赖的目标垂直方向 |
| vertical_reverse 依赖的目标垂直方向 |
| relative_to_dependence 相对与依赖的滚动目标位置 |
|---|
| toLeft 在依赖的左边 |
| toRight 在依赖的右边 |
| toTop 在依赖的上边 |
| toBottom 在依赖的下边 |
| alignLeft 对齐依赖的左边 |
| alignRight 对齐依赖的右边 |
| alignTop 对齐依赖的上边 |
| alignBottom 对齐依赖的下边 |
| follow 仅仅跟随滚动 |
