我这个下面的资源库在这里工作：

I am working with this following Repository here:

CheeseSquare回购经克里斯·巴内斯

整体而言，这是很好的资源库，但缺乏复杂布局方案。我要实现的是这样的：

Overall it is good repository but lacks complex layout schemes. I want to achieve something like this:

当DO SOMETHING按钮包含在 AppBarLayout 和嵌套在 Col​​lapsingToolbarLayout ，它崩溃，你向上滑动。那是我最初的想法，但它似乎不给我，我要找的行为。

Where the "DO SOMETHING" button is contained inside AppBarLayout and nested inside CollapsingToolbarLayout, and it collapses as you scroll up. That is my original thought, but it doesn't seem to give me the behavior I am looking for.

这是我的XML布局是这样的：

This is what my XML Layout looks like:

<android.support.design.widget.CoordinatorLayout>

<android.support.design.widget.AppBarLayout>

    <android.support.design.widget.CollapsingToolbarLayout>

        <ImageView />

        <android.support.v7.widget.Toolbar />

    </android.support.design.widget.CollapsingToolbarLayout>

    <Button/>

</android.support.design.widget.AppBarLayout>

<android.support.v4.widget.NestedScrollView>

    <LinearLayout>

        <android.support.v7.widget.CardView>
            <LinearLayout>
                <TextView/>
            </LinearLayout>
        </android.support.v7.widget.CardView>

    </LinearLayout>

</android.support.v4.widget.NestedScrollView>

<android.support.design.widget.FloatingActionButton />

如何去实现这样的事情？

How would I go about accomplishing something like that?

推荐答案

我可以通过实施来解决这个问题，以下内容：

I was able to solve this issue by implementing the following:

<android.support.design.widget.CoordinatorLayout>

    <android.support.design.widget.AppBarLayout>

    <android.support.design.widget.CollapsingToolbarLayout
        app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                app:layout_collapseMode="parallax"/>

            <android.support.v7.widget.Toolbar />

        </android.support.design.widget.CollapsingToolbarLayout>

    </android.support.design.widget.AppBarLayout>

    <LinearLayout
        app:layout_behavior="@string/appbar_scrolling_view_behavior" >

        <!-- BUTTON INSERTED HERE -->
        <Button />
        <android.support.design.widget.TabLayout />
        <android.support.v4.view.ViewPager />

    </LinearLayout>

</android.support.design.widget.CoordinatorLayout>
