(Design Support Library) CollapsingToolbarLayout — Toolbar not getting pinned on collapse

问题

I'm having trouble integrating the Design Support Library into my application. For some reason, the toolbar collapses with the CollapsingToolbarLayout, and does not leave it pinned like in the Cheesesquare example by Chris Banes. https://github.com/chrisbanes/cheesesquare

I didn't do anything different to my layout. In fact, I replaced my styles with his, and dropped in his layout. I wonder if using Toolbar, instead of android.support.v7.widget.Toolbar is causing this.

Here is the problem.

Here is my XML of the AppBar section.

<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_height="match_parent"
    android:fitsSystemWindows="true">


    <android.support.design.widget.AppBarLayout
        android:id="@+id/appbar"
        android:layout_width="match_parent"
        android:layout_height="@dimen/detail_backdrop_height"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        android:fitsSystemWindows="true">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleMarginEnd="64dp">

            <ImageView
                android:id="@+id/backdrop"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                app:layout_collapseMode="parallax" />

            <Toolbar
                android:id="@+id/toolbar"
                android:layout_width="match_parent"
                android:layout_height="?attr/actionBarSize"
                app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
                app:layout_collapseMode="pin" />

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

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

    ...

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

回答1:

Your intuition was correct: CollapsingToolbarLayout does rely on you using the support Toolbar - it uses that to set the minimum height of the CollapsingToolbarLayout (among many other things). You should switch to using the support version of the Toolbar to ensure the best experience with CollapsingToolbarLayout.

回答3:

Use app:layout_collapseMode="pin" to ensure that the Toolbar itself remains pinned to the top of the screen while the view collapses.
Even better, when you use CollapsingToolbarLayout and Toolbar together, the title will automatically appear larger when the layout is fully visible, then transition to its default size as it is collapsed.
Note that in those cases, you should call setTitle() on the CollapsingToolbarLayout, rather than on the Toolbar itself.

For more details about implementation visit Android Developers Blog or details about package CollapsingToolbarLayout
