I have some issues trying to implement the new CollapsingToolbarLayout
. Scrolling, expanding and collapsing do work fine, but my ImageView
(no matter what type of resource I set) does not cover the full height of the expanded toolbar. See here:
Here I set android:src="@color/red"
on the image view, but it never covers the real toolbar. It doesn't work with bitmaps either. I am posting my layout below.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<!-- content -->
<android.support.design.widget.CoordinatorLayout
android:fitsSystemWindows="true"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:layout_height="@dimen/appbar_expanded_height"
android:layout_width="match_parent"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:expandedTitleMarginStart="48dp"
app:expandedTitleMarginEnd="64dp"
app:contentScrim="?attr/colorPrimary"
android:fitsSystemWindows="true">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
android:src="@color/red_600"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"
/>
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
app:layout_collapseMode="pin"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize">
</android.support.v7.widget.Toolbar>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<!-- I load fragments here -->
<FrameLayout
android:id="@+id/fragment_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
<!-- nav drawer -->
<fragment
android:layout_width="@dimen/drawer_width"
android:layout_height="match_parent"
android:layout_gravity="start"/>
</android.support.v4.widget.DrawerLayout>
Seems to me that the only difference with, for example, the cheese-Chris Banes-app, is that I'm giving app:layout_behavior
to a FrameLayout
. However, inside that frame I load fragments that have a NestedScrollView
as the root view, and this seems to work fine.
I had the same problem, the collapsing toolbar did not cover the full height of Image, But fixed with removing single line from the AppBarLayout
. That is you just need remove android:fitsSystemWindows="true
and you are done.
<android.support.design.widget.AppBarLayout
android:layout_height="@dimen/appbar_expanded_height"
android:layout_width="match_parent"
android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:fitsSystemWindows="true">
remove the last line, that is as.
android:fitsSystemWindows="true"
that's it, good to go...
I found the blue strip was the toolbar background. Namely, I had:
<item name="toolbarStyle">@style/MyToolbarStyle</item>
in my theme, and:
<style name="MyToolbarStyle">
<item name="android:background">?attr/colorPrimary</item>
</style>
I used to have this to tint toolbars with colorPrimary
. However if you want to move to the design library, you should get rid of it: the collapsed toolbar color is already managed by the app:contentScrim
attribute on the CollapsingToolbarLayout
.
