How to prevent toolbar from collapsing after scroll?

After scroll, I don't want the toolbar to collapse but only the ImageView, similar to exitUntillCollapsed. But I want the app bar to expand on slightest downward scroll. How do I achieve this?
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsingToolbarLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/imageViewCollapsing"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="centerCrop"
android:src="#drawable/winterscenery"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>

For scroll behaviour pls use flag enterAlways
For Fix toolbar layout pls add toolbarlayout above your coordinatorLayout.
<LinearLayout 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:orientation="vertical">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.CoordinatorLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">

How to use collapsing toolbar for vertical views

In my activity,I have a toolbar and the view should be displayed below toolbar (Like Linearlayout) and listview as follows,
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.example.xyz.abc.MainPage">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay"
android:id="#+id/view">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<RelativeLayout
app:layout_collapseMode="parallax"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<FrameLayout
android:background="#android:color/transparent"
android:id="#+id/header_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
<TextView
android:layout_below="#+id/header_content"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="#+id/progress"
/>
</RelativeLayout>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
app:layout_collapseMode="pin"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<FrameLayout
app:layout_behavior="#string/appbar_scrolling_view_behavior"
android:id="#+id/body_content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
</RelativeLayout>
I want to use hide the view below toolbar (Relative layout) when the listview is scrolled like this. But It is not working for my case . I tried every solution in this post . Even changing CoordinatorLayout to RelativeLayout doesn't work.
In my xml, the framelayouts will be replaced at runtime.
Guide me, Thanks in advance

You have to use scrollview or nested scrollview with collapsing toolbar.
<android.support.design.widget.AppBarLayout
android:id="#+id/appbar_"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="?attr/colorPrimary"
android:fitsSystemWindows="true">
<android.support.design.widget.CollapsingToolbarLayout
android:id="#+id/collapsing_toolbar"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:expandedTitleMarginBottom="32dp"
app:expandedTitleMarginEnd="64dp"
app:expandedTitleMarginStart="48dp"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<ImageView
android:id="#+id/header"
android:layout_width="match_parent"
android:layout_height="192dp"
android:background="#color/colorPrimary"
android:fitsSystemWindows="true"
android:scaleType="centerCrop"
android:src="#drawable/bg2"
app:layout_collapseMode="parallax" />
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
Use Scrollview here
Now you can continue with your framelayout or watevr you want to use

Status bar moving down when open collapsing toolbar (with parallax image effect)

I have a problem with collapsing toolbar layout. I would like to create collapsing toolbar with parallax effect. I read a lot of tutorials and everything is ok except one little element. The background of status bar is moving down while scrolling NestedScrollView quickly. I would like to create profile like in Facebook app.
I am attaching a video which shows my problem (in this video I am showing borders of layouts).

Also this is my layout:

Could you help me to resolve this problem ?

I had the exact same problem and it turns out that it was because of the android:fitsSystemWindows="true" property on the android.support.design.widget.AppBarLayout element.
If you remove that, it should work.
Here is my layout.xml:

Material Design - Toolbar and Tab Layout overlaps when scrolling

I'm designing a collapsing toolbar with tab layout. When collapsing toolbar layout is shown fully, it is shown as i want.
I want to make toolbar and tab bar fixed even if any scroll occurs. However when the appbar is collapsed, the toolbar and the tablayout overlaps as shown below:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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:id="#+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
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="wrap_content"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed"
app:titleEnabled="false"
android:fitsSystemWindows="true">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#drawable/image"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"
android:fitsSystemWindows="true"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:gravity="top"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"
app:titleMarginTop="13dp"
app:title="sample_pager_tabs_parallax_image"/>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:layout_collapseMode="pin"/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>
I put the
android:layout_marginTop="100dp"
android:fitsSystemWindows="true"
inside TabLayout, however it does not work.
Putting the TabLayout out of CollapsingToolbarLayout solves the overlapping problem. However, i want to make parallax images shown in status bar, toolbar and tab bar as shown below :

Take the TabLayout out of the CollapsingToolbarLayout and move it into the AppBarLayout, this should solve your problem.
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"

app:titleMarginTop="13dp"
app:title="sample_pager_tabs_parallax_image"/>
</android.support.design.widget.CollapsingToolbarLayout>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
app:layout_collapseMode="pin"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.design.widget.CoordinatorLayout>

I found the solution of this issue just add this line in your toolbar layout.
android:layout_marginBottom="48dp"

Do these things:
1.put the <android.support.design.widget.TabLayout out of CollapsingToolbarLayout and add it under AppBarLayout
2.Remove android:fitsSystemWindows="true" from CoordinatorLayout
3.Also apply app:layout_scrollFlags="scroll|enterAlways" to the Toolbar to make it fix in top poition

Change your Toolbar height. Use android:layout_height="104dp" instead of android:layout_height="?attr/actionBarSize".
Remove attribute app:layout_collapseMode="pin" from TabLayout.
Try this:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="#+id/main_content"
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">

Menu options not showing on Collapsing Toolbar

I am trying to implement a Collapsing Toolbar Layout with menu options but whenever I set the image view source in the below code, the image covers the menu and the back button. The options are there as I can click on them, they are just hidden by the image. Does anyone know how to fix this?

if any trouble leave comment
good luck !

From own experience this tells me this you probably have forgotten to add the following lines to the activity:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

Try adding collapseMode attributes to the Toolbar...like this. It pins the toolbar.
<android.support.v7.widget.Toolbar
app:layout_collapseMode="pin" />
