How to add a gradient to a ImageView nested in a CollapsingToolbar

How to add a gradient to a ImageView nested in a CollapsingToolbar - android

I'am working on an Android app with material design. I have a detail view with a CollapsingToolbarLayout and a ImageView (works fine so far). Unfortunately the title is not readable if there is a bright image.
So far I tried to add a gradient (Add gradient to imageview) but this solution didn't work for me because of the CollapsingToolbarLayout.
Here you can see my code:
<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_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_height="256dp"
android:layout_width="match_parent"
android:fitsSystemWindows="true"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<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"
app:contentScrim="#color/primary"
android:fitsSystemWindows="true"
app:expandedTitleMarginEnd="50dp"
app:expandedTitleMarginStart="50dp"
>
<!--<View
android:background="#drawable/actionbar_gradient_dark"
/>-->
<ImageView
android:id="#+id/backimg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
android:scaleType="centerCrop"
app:layout_scrollFlags="scroll|enterAlways"
/>
<android.support.v7.widget.Toolbar
android:id="#+id/detailToolbar"
android:layout_height="?attr/actionBarSize"
android:layout_width="match_parent"
app:layout_collapseMode="pin"
app:layout_collapseParallaxMultiplier="0.7"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.CollapsingToolbarLayout>
Does anyone know a solution for this issue?

Wrap your ImageView in a FrameLayout and add a View with a background:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:id="#+id/backimg"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
android:scaleType="centerCrop"
android:src="#drawable/image"
app:layout_scrollFlags="scroll|enterAlways" />
<View
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/actionbar_gradient_dark" />
</FrameLayout>
Make sure your gradient is something like this:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle" >
<gradient
android:angle="90"
android:endColor="#android:color/transparent"
android:startColor="#android:color/black" />
<corners android:radius="0dp" />
</shape>

Shadow/Elevation from Collapse Tool Bar Don'tWork With Recycler View?

I'm studying the Udacity Material Design for Android Course.
In the classes "Making Scrollable Dinamic Surface" I learn how make a action bar that change size with scrolling.
But this example works with a ScrollView for the content.
When I try to use a RecyclerView I lost the Shadow effect between action bar and content.
Should I set something different?
Thanks.

I found a solution for this.
In your XML you can add a Animator (last line)
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="210dp"
android:background="#color/neah_screen_bg_white"
android:stateListAnimator="#animator/appbar_always_elevated">
You create this XML file in res/animator
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<objectAnimator
android:propertyName="elevation"
android:valueTo="4dp"
android:valueType="floatType"
android:duration="1"/>
</item>
</selector>

Elevation is not shown on toolbar in pre-lollipop devices

I want to show the same elevation effect on my toobar on a KitKat device as seen on a Lollipop device. Below are screenshots for both the KitKat and Lollipop devices. I have referred to this link but my problem is not solved yet.

As mentioned, elevation is not available below lollipop devices but, there are few alternative ways for doing that.
I've personally tried everything and none worked but could managed it by adding a layout-v19 folder in res folder of project. So, it will be a specific API-19 layout. There, you can add a view under Toolbar-AppbarLayout (depends on your design) with 4dp height or any other methods as following links:
https://github.com/vipulasri/Toolbar-Elevation-Pre-Lollipop
And this: https://mobikul.com/show-shadow-toolbar-api-21/
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<include
android:id="#+id/toolbar"
layout="#layout/toolbar" />
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<!-- Place Your Layout Here -->
<View
android:id="#+id/shadow_view"
android:layout_width="match_parent"
android:layout_height="5dp"
android:background="#drawable/dropshadow" />
</FrameLayout>
</LinearLayout>
dropshadow.xml:
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<gradient android:startColor="#android:color/transparent"
android:endColor="#60555555"
android:angle="90"/>
</shape>
And in java-kotlin side, check if it is API-19, then inflate the layout there:
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
v = inflator.inflate(R.layout.item_showdetail_asset_kitkat, this);
} else {
v = inflator.inflate(R.layout.item_showdetail_asset, this);
}
Hope this helps.

Collapsed
Expanded

I had the same issue and found a solution:
First you have to update to the latest Support Library (I use 24.1.0)
Then apply the stateListAnimator to your AppBarLayout:
example:
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="320dp"
android:stateListAnimator="#drawable/appbar_always_elevated"
android:fitsSystemWindows="true">
and use this xml as animator:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<objectAnimator android:propertyName="elevation"
android:valueTo="8dp"
android:valueType="floatType"
android:duration="1"/>
</item>
</selector>

You can find official stateListAnimator for AppBarLayout here
1. Put this appbar_elevation.xml into resources directory named animator-v21
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android"
tools:ignore="PrivateResource">
<item>
<objectAnimator
android:propertyName="elevation"
android:valueTo="#dimen/design_appbar_elevation"
android:valueType="floatType" />
</item>
</selector>
2. On AppBarLayout set android:stateListAnimator="#animator/appbar_elevation"

Just use
app:liftOnScroll="false"
on the AppBarLayout

How to make a gradient shape stay behind CollapsingToolbarLayout title

I've been playing around with Chris Bane's Cheesesquare example application regarding Collapsing Toolbar Layout and I'm having trouble adding a gradient behind the title on a collapsing toolbar so the title remains readable even if the backdrop is bright.
I've seen one solution here on stackoverflow that deals with this in a way.
That solution places the gradient "attached" to the image itself instead of the bottom of the Collapsing toolbar. What will happen is, as you scroll down, that gradient will disappear with the image as it parallaxes out of sight. I want to make the gradient follow the toolbar as it collapses (and keep the parallax effect).
This short video should make the issue clear: https://vid.me/J225

Any help is very welcome!

Silly me, I came back to the issue and found a solution. #whaleswallace made me realize CollapsingToolBarLayout extends FrameLayout itself (so you don't need to wrap the image and gradient view in one) so it was a matter of adding android:layout_gravity="center_horizontal|bottom to the gradient view:
<android.support.design.widget.CollapsingToolbarLayout
....>
<ImageView
android:id="#+id/backdrop"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"/>
<View
android:layout_width="match_parent"
android:layout_height="72dp"
android:background="#drawable/backdrop_bg"
android:layout_gravity="center_horizontal|bottom"/>
<android.support.design.widget.CollapsingToolbarLayout/>
The image will be "parallaxing" in and out and the gradient will keep anchored to the bottom of the AppBarLayout.

CollapsingToolbarLayout not working(collapsing)when scrolled

I am trying to create a CollapsingToolbarLayout and below it a listview, when the listview is scrolled the Toolbar should collapse, but its not working when scrolled the Toolbar is not collapsing.
Used this tutorial: http://android-developers.blogspot.in/2015_05_01_archive.html
Note: The FrameLayout contains the listview

android:layout_width="match_parent"

android:orientation="vertical"
android:scrollbars="vertical">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="192dp"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbara"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</LinearLayout>
The framelayout code:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_alignParentRight="true"
android:layout_marginBottom="10dp"
android:layout_marginRight="10dp"

app:elevation="5dp"
app:rippleColor="#color/wallet_highlighted_text_holo_light" />
</RelativeLayout>

You should use RecyclerView instead of ListView
Note:
don't forget to update RecyclerView in Gradle file.
compile 'com.android.support:recyclerview-v7:22.2.0'

I did an example by using RecyclerView instead. The source code could be found here:
https://github.com/jiahaoliuliu/MaterialDesignSample/tree/collapsingToolbars
There are a couple of things that you should take into account and the post does not says.
Use CoordinatorLayout as the main layout
Use a theme without ActionBar and set the toolbar as actionBar instead. You can do it by creating a special theme for the activity like this:
<!-- Indigo without actionbar when toolbar is used -->
<style name="IndigoWithoutActionBar" parent="Indigo">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
And in the AndroidManifest.xml file, do the follow:
<activity
android:name=".CollapsingToolbarActivity"
android:label="#string/app_name"
android:theme="#style/IndigoWithoutActionBar"
>
</activity>
Once this is done, set it on the Java code:
// Actionbar
final Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
Here is a functional xml code that I use.
<?xml version="1.0" encoding="utf-8"?>

If this is not enough for you, you can follow the code of Chris Banes here:

For my case : I dint give height to my Toolbar .
It was wrap_content. If thats the case then try to fix the height of the Toolbar using :-
android:layout_height="?attr/actionBarSize"

You need to add two things to the list view and it will work
android:nestedScrollingEnabled="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
My working XML code is

Hopefully help someone.

The problem is the RelativeLayout. Try replacing the FrameLayout with the ListView and then the FloatingButton. All wrapped in a CoordinatorLayout of course.

<FrameLayout
android:id="#+id/frame"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
