I'm working with the CollapsingToolbarLayout from the new Android Design Support Library.
I have set its title and it is working fine, the only problem I still have is that when you scroll, the text is lost, depending on the image in the background.
What I'd like to do, is set a background to the CollapsingToolbarLayout title, but I haven't find a way to do it.
Is there anyway to achieve this?

Setting up the CollapsingToolbarLayout title in the activity:
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle("Some title here");
Edit:
Here you can see a sequence of images when I collapse the toolbar. You can see how the title text is not readable. The problem is that I don't have control of the images that I show, so for some images it looks ok, but for others, like this example, it doesn't look good at all and it is not readable. What I had in mind was maybe add some kind of background to the text, so there is always the same color at the back of the text and it is always readable.
Use a text protection scrim(scroll down a bit). My example assumes the title text is white, so some tweaks may be necessary to optimize for your case.
Inside your CollapsingToolbarLayout, add the following after ivBigImage:
<View
android:layout_width="match_parent"
android:layout_height="#dimen/sheet_text_scrim_height_top"
android:background="#drawable/scrim_top"
app:layout_collapseMode="pin"/>
<View
android:layout_width="match_parent"
android:layout_height="#dimen/sheet_text_scrim_height_bottom"
android:layout_gravity="bottom"
android:layout_alignBottom="#+id/image"
android:background="#drawable/scrim_bottom"/>
In your Drawable folder, add:
scrim_top.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="270"
android:startColor="#color/translucent_scrim_top"
android:centerColor="#color/translucent_scrim_top_center"
android:endColor="#android:color/transparent"/>
</shape>
and scrim_bottom.xml
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient
android:angle="90"
android:startColor="#color/translucent_scrim_bottom"
android:centerColor="#color/translucent_scrim_bottom_center"
android:endColor="#android:color/transparent"/>
</shape>
For colors, you should make these darker in initial testing so it's more obvious you have it working, but for production I used:
<color name="translucent_scrim_top">#26000000</color>
<color name="translucent_scrim_top_center">#0C000000</color>
<color name="translucent_scrim_bottom">#2A000000</color>
<color name="translucent_scrim_bottom_center">#0D000000</color>
And for dimensions, I used a height of 88dp.
Use a text protection scrim from the example of Amagi82 and add on the CollapsingToolbarLayout the app:expandedTitleTextAppearance parameter.
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
.
app:expandedTitleTextAppearance="#style/TextAppearance.Design.CollapsingToolbar.Expanded.Shadow"
.
.
app:layout_scrollFlags="scroll|exitUntilCollapsed">
For example add this on you style xml:
<style name="TextAppearance.Design.CollapsingToolbar.Expanded.Shadow">
<item name="android:shadowDy">0</item>
<item name="android:shadowDx">0</item>
<item name="android:shadowRadius">8</item>
<item name="android:shadowColor">#android:color/black</item>
</style>
Edit:
If you want to change the color of the toolbar once it has "shrunk", you need to set the contentScrim attribute of the collapsing toolbar layout to that color:
<android.support.design.widget.CollapsingToolbarLayout
app:contentScrim="#color/[color you want]"
...>
Pointing the value of this attribute to the color you want the toolbar to turn into will solve your issue, as I understand it.
Hope that answers your question!
That's a lot of work do achieve here by writing that much of code.
I achieved that by 2 ways.
1 A simple workaround by using a View with TransparentBlack color
CODE>>
Code explaination:1 The CollapsingToolbarLayout has a style with only a text size.2 Default CollapsingToolbarLayout margin bottom is overridden to 16dp.3. Our header with parallax collapseMode is a RelativeLayout with an ImaveView and a View.4. This simple View with a BG at the bottom of the top header Relative layout with colour of contrast (here #77000000), acts as the BG for CollapsingToolbarLayout's collapsed Title in white color.
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/redeem_detail_collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/color_window_background"
android:fitsSystemWindows="true"
app:expandedTitleMarginBottom="16dp"
app:expandedTitleTextAppearance="#style/CollapsingTitleStyle"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<!--header view-->
<RelativeLayout
android:layout_width="match_parent"

Problem : Trying to achieve Toolbar with arched bottom. The content when scrolling should go through this arc space.
Only thing I could think of (as well as tried) is to set the background of toolbar with a drawable which has arch. Lookwise it solves things. But then when the content is scrolled up, the white space in the arch remain, since Toolbar maintains it's rectangle shape.
I'm also trying to avoid using custom shapes instead of Toolbar because this toolbar is part of a Collapsibletoolbarlayout and Appbarlayout controlled by Coordinator layout.
Any suggestions ?
This can be done fairly easily.
<android.support.design.widget.CoordinatorLayout
android:layout_height="match_parent"
android:layout_width="match_parent"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#0000"
app:elevation="0dp">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/colorPrimary"
app:layout_collapseMode="pin"/>
<!--Other collapsing toolbar components here-->
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<!--Your content here-->
</android.support.v4.widget.NestedScrollView>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#drawable/curve"
app:layout_anchor="#id/appBar"
app:layout_anchorGravity="bottom"
android:layout_gravity="bottom"/>
</android.support.design.widget.CoordinatorLayout>
The FrameLayout anchored to the bottom of the AppBarLayout acts as the container for the arch. I created a vector drawable that I used as the background for the FrameLayout
curve.xml
<vector android:width="100dp"
android:height="40dp"
android:viewportHeight="50"
android:viewportWidth="400"
xmlns:android="http://schemas.android.com/apk/res/android">
<path
android:pathData="M0,0L400,0L400,50Q200,-50,0,50L0,0"
android:fillColor="#color/colorPrimary"/>
</vector>
Change the android:height property of the drawable to control how high you want the arch to go

SCREENSHOT
Got it solved. The image from the network was of a different ratio, one thing i discovered is that if the image don't fit the res to go behind the status bar then it automatically fits under the status bar. All i had to do is set android:scaleY="1.2" in the NetworkImageView to push it into the status bar.
On devices with API 21+ you can use a custom theme that make the status bar translucent.
<style name="AppTheme.NoActionBar.NoStatusBar">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">#android:color/transparent</item>
</style>
Add this style to a file within the values-v21 folder and set the Activty theme in your AndroidManifest.xml like this:
<activity
android:name=".activity.AboutActivity"
android:theme="#style/AppTheme.NoActionBar.NoStatusBar" />
And one more thing. I think you need to add android:fitsSystemWindows="true" to the NetworkImageView also.
I would like to achive the following layout:
Map as a base layout
Transparent window above inside a CollapsingToolbarLayout
RecyclerView for content
I included an example of how this should look like.
I was following this great example from Cheesesquare for the CollapsingToolbarLayout and AppBarLayout implementation. I managed to get the content working with the map inside the CollapsingToolbarLayout (commented out in the layout xml), but this is not the desired result.
However I did not find any solution / documentation to make the grey box (see inside image in the middle) to be transparent in the initial position. I would like it to be transparent in order to see through to the map. When the user would scroll up, the CollapsingToolbarLaoyut should do it's work and collapse the transparent window and show the Toolbar. For now the image looks just white or whatever color I give it. I already tried to set the color to transparent, but it didn't have the desired effect.
So my question: How could I set the "CollapsingToolbarLayout" transparent in the initial phase (see image Layer 1 grey box)?
Here is my code for the layout. The CollapsingToolbarLayout works great, but I can't see the map below. Would be great if it would be possible to implement.

How could I set the "CollapsingToolbarLayout" transparent in the
initial phase (see image Layer 1 grey box)?
Try to use this in your AppBarLayout: android:background="#android:color/transparent"
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="#android:color/transparent"
android:fitsSystemWindows="true">
Here is the result:
I'm trying to utilize the CoordinatorLayout, AppBarLayout, CollapsingToolbarLayout, Toolbar and a parallax'ed ImageView. It looks like the ripple effect of the toolbar menu items is cropped. The following image displays the ripple effect of the back button in expanded and in partially collapsed mode. In complete collapsed mode the ripple effect is not shown at all. I think this is caused by the parallax'ed ImageView that is positioned there.

The ImageView displays a 9-patch'ed Image. Is there something wrong with the layout or is it a bug/inability in the design support library to draw the ripple ontop of the ImageView?
I think your solution is here.
You can try to add this line:
<item name="actionBarItemBackground">?attr/selectableItemBackground</item>
in the theme/style of your Toolbar.
If it doesn't work, add this in your Toolbar attributes:
android:background="#android:color/transparent"
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.

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.
