本文详细探讨了Android中CoordinatorLayout、AppBarLayout和CollapsingToolbarLayout的使用，包括fitsSystemWindows属性、背景色设定、内容颜色以及滑动行为的配置。通过设置滑动标志、折叠模式和滚动倍数，实现滑动隐藏布局与Toolbar的完美交互。

1，CoordinatorLayout

android:fitsSystemWindows="true"

2，AppBarLayout

android:background="#ffffff" // 设置头部的背景色，替换系统颜色

android:fitsSystemWindows="true"

   app:elevation="@dimen/0dp" 设置toobar没有卡片效果

3，CollapsingToolbarLayout

android:fitsSystemWindows="true"

app:contentScrim="@color/color_FFFFFF". // 设置标题栏在折叠后的内容颜色

app:statusBarScrim="@color/color_FFFFFF" // 设置标题栏在折叠后的状态栏颜色

3.1 内部的控件.(滑动隐藏的布局，可以解决滑动后布局消失时与toolbar有重叠部分的问题)

app:layout_scrollFlags="scroll|exitUntilCollapsed"

app:layout_collapseMode="parallax"

app:layout_collapseParallaxMultiplier="1"

3.2 toolbar （设置滑动toolbar不隐藏）

app:layout_collapseMode="pin"
