layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior"

RecyclerView 提供相當多種控制Scroll的方法
1.scrollBy(int x, int y)

AppBarLayout無法滑動時可透過設定DragCallback解決此問題

CoordinatorLayout.LayoutParams tParams = (CoordinatorLayout.LayoutParams) m_AppBarLayout.getLayoutParams();

當你的線性漸層所需要的顏色不只3種時:
用ShapeDrawable或PaintDrawable

GradientDrawable(Orientation orientation, @ColorInt int[] colors)
