1.控件简介。

CoordinatorLayout遵循Material 风格,包含在 support Library中,结合AppbarLayout, CollapsingToolbarLayout等 可 产生各种炫酷的折叠悬浮效果。

    作为最上层的View
    作为一个容器与一个或者多个子View进行交互

    CoordinatorLayout is intended for two primary use cases: As a top-level application decor or chrome layout; As a container for a specific interaction with one or more child views.

常见结合体-AppBarLayout:

它是继承与LinearLayout的,默认的方向是Vertical:

appbarLayout的滑动flag:

我们可以通过两种方法设置这个Flag:

    方法一:setScrollFlags(int)
    方法二:app:layout_scrollFlags="scroll|enterAlways"

AppBarLayout必须作为CoordinatorLayout的直接子View,否则它的大部分功能将不会生效,如layout_scrollFlags等。

        </androidx.appcompat.widget.Toolbar>

    </FrameLayout>

</layout>

注意一点:那个可滑动的 View 不能是 ListView,ScrollView 这种旧包下的控件,否则也是不起作用的。

app:layout_scrollFlags="scroll|enterAlways,前面已经说到app:layout_scrollFlags=scroll的时候,这个View会跟着滚动事件响应,app:layout_scrollFlags=“enterAlways”的时候这个View会响应下拉事件。所以呈现出来的结果应该是我们在上拉的时候toolBar会隐藏,下拉的时候toolBar会出来;如果当我们的toolBar等于app:layout_scrollFlags="scroll|snap"的时候 ,app:layout_scrollFlags=scroll的时候,这个View会跟着滚动事件响应,app:layout_scrollFlags=“snap”的时候在Scroll滑动事件结束以前 ,如果这个View部分可见,那么这个View会停在最接近当前View的位置。具体就自己研究了。

再说我这个需求的效果:标题栏常驻,有两个Toolbar,第一个Toolbar实际上是一个占位View,第二个Toolbar才是真正的常驻标题栏,上滑的时候沉浸式标题栏渐变,上滑到二级标题与标题栏吸顶,app:layout_scrollFlags="scroll|exitUntilCollapsed",上拉的时候,这个View会跟着滑动直到折叠成第一个Toolbar大小,下方的ViewPager设置app:layout_behavior="@string/appbar_scrolling_view_behavior"属性才可以与Toolbar进行吸顶,这样就与第二个Toolbar正常吸顶了。
