CollapsingToolBarLayout has dual toolbar - android

I am having issues with implementing CollapsingToolbarLayout. I have this problem:
Yes, I've got to place the view in the layout, but it collapses below the original toolbar (or ActionBar for that matter) as shown in the image below. I have no idea how to fix this.
Thanks for any help. I am using Android Studio 2.1.1.
Here is my layout file:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout

<WebView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/article_container" />
</FrameLayout>
<android.support.design.widget.FloatingActionButton
android:id="#+id/share"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#mipmap/ic_share_variant" />
</android.support.design.widget.CoordinatorLayout>

I found out where I went wrong. I had left out the theme statement in the manifest. All I had to do was add the line android:theme="AppTheme.NoActionBar" to my activity in the manifest.
However, this brought up two new issues:
The new ToolBar scrolls out of view (does not stick to the top.)
The back button that should lead me to my previous activity is gone. However, I'll ask this as a separate question if I do not get the solutions from researching.

I have seen all the tutorial on GitHub and other sites. and used but I could not get the solution. Any easy way to the parallax sticky header for the fragment. and right now I am following the code of https://android.jlelse.eu/parallax-scrolling-header-tabs-android-tutorial-2cc6e40aa257 and see the documentation of android developer about the CollapsingToolbarLayout.
I don't know why exactly you would be getting that error, but this might be a good start.

Otherwise I found this really good tutorial on mastering the coordinator layout which has a github repo with a bunch of great examples with the collapsing toolbar layout that helped me when I developed one.

Try adding this to your app build.gradle:
dependencies {
...
implementation 'com.google.android.material:material:1.1.0'
...
}

JAVA:
CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle("Title");
It shows me this on android studio:
But when I run it, it just shows me this:
I've even tried to use android.support.v4.widget.NestedScrollView instead of ScrollView but it didn't work either.
Any idea what I'm doing wrong ???
Change the height of NestedScrollView to Wrap_content instead of match_parent, it is occupyig entire screen. Hope that works for you.

You can call appBarLayout.setExpanded(true) to expand the app bar layout and appBarLayout.setExpanded(false) to collapse it.
To lock the app bar layout into the expanded or collapsed state, call setNestedScrollingEnabled(false) on the scrolling view that moves the app bar. That view will somewhere in the view hierarchy of the fragment in your fragment container.

CollapsingToolbarLayout image to persist when scrolling to top like the Play Store app

I have a CollapsingToolbarLayout with an image and text in it. Below is the layout:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
xmlns:tools="http://schemas.android.com/tools"

android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar"
custom:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
android:layout_width="match_parent"
android:layout_height="#dimen/appbar_image_height"
android:fitsSystemWindows="true"
android:background="#color/red"
custom:layout_scrollFlags="scroll|exitUntilCollapsed">
<android.support.design.widget.CollapsingToolbarLayout

custom:contentScrim="#color/red"
custom:statusBarScrim="#color/primary_dark"
custom:expandedTitleTextAppearance="#android:color/transparent"
android:fitsSystemWindows="true"
custom:layout_scrollFlags="scroll|exitUntilCollapsed">
<RelativeLayout
style="#style/HmatchWmatch"
android:fitsSystemWindows="true"
custom:layout_collapseMode="parallax"
custom:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/toolbar_iv"
style="#style/HmatchWmatch"
android:scaleType="centerCrop"
tools:ignore="ContentDescription"/>
<TextView
android:id="#+id/toolbar_title"
style="#style/TextLarge.Pad"
android:layout_width="match_parent"
android:layout_alignParentBottom="true"
android:paddingBottom="#dimen/vpad"
android:background="#drawable/appbar_title_bg"
android:textColor="#android:color/white"
android:maxLines="2"/>
<TextView
android:id="#+id/toolbar_dm"
style="#style/TextSmall.Pad"
android:layout_width="match_parent"
android:layout_above="#id/toolbar_title"
android:paddingTop="#dimen/vpad"
android:background="#drawable/appbar_dm_bg"
android:textColor="#android:color/white"
android:maxLines="2"/>
</RelativeLayout>
<include
android:id="#+id/toolbar"
layout="#layout/toolbar"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<fragment
android:id="#+id/fragment"
android:name="com.Fragment"
style="#style/HmatchWmatch"

style="#style/TextMedium"
android:layout_width="match_parent"
android:text="#string/sign_button_text"
android:textColor="#android:color/white"/>
</android.support.design.widget.CoordinatorLayout>
And below is the layout for the toolbar:
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:custom="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/change_red"
custom:layout_scrollFlags="scroll|enterAlways"
custom:layout_collapseMode="pin"
tools:ignore="Overdraw"/>
When scrolling up, the image disappears and it becomes the toolbar which is pinned at the top. What I want to achieve is like in the Play Store app, when scrolling up in a particular app, the image disappears when scrolled up and the toolbar appears in the screen when scrolled down again. How can I achieve that in my case?
My problem is that I want the Appbar to scroll off the screen completely when scrolled up and when scrolling down again, the toolbar should appear.
I have tried various method but I don't think nothing helped to implement the exact way of Play Store animation and design (using design library)! Out of all the following matches almost similar. This is almost similar to what #MicheleLacorte suggested in comment!

android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="#drawable/background"
app:layout_collapseMode="parallax"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?android:attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/AppTheme.PopupOverlay"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/content_scrolling"/>
</android.support.design.widget.CoordinatorLayout>
In case if you want the exact same implementation then you have to look into some third party libraries! Just giving the link for some of third party libs in case if you are interested!

Top of content in CollapsingToolbarLayout obscured by Toolbar background colour

I'm seeing an issue with my app when using the Android design support library in that the CollapsingToolbarLayout appears to have a theme-coloured background bar at the top, even when there is enough space (and therefore it should be 'transparent').
Any ideas what I'm doing wrong?

I'm having very similar layout in my app and it's working well for me. Comparing mine layout to yours, my guess is you should remove background attribute from your Toolbar. Furthermore, I use one of the default themes for Toolbar (#style/ThemeOverlay.AppCompat.Dark). I see you're using your own theme, which might be causing problem as well. (I set StatusBar color to transparent in Java code, if you're interested in that too).
