refer to the image, I want to create a parallax scrolling effect within a viewpager. the ImageView and the webview is the layout from the view pager fragment while the toolbar is on the activity that hold the viewpager.
I had my parallax scrolling effect working but not the show and hide toolbar below is my code for both activity and fragment.
main.xml
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

<!--<TextView

<WebView
android:id="#+id/webview"
android:layout_width="match_parent"
android:layout_height="match_parent"></WebView>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
so my question is how to make toolbar in activity get the scrolling behaviour in the fragment and show or hide when user scroll up and down
you will have to do it the following way
<CoordinatorLayout>
<AppBarLayout>
<Toolbar >
<ImageView
app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="centerCrop"
app:layout_collapseMode="parallax"
android:minHeight="100dp"/>
</Toolbar>
</AppBarLayout>
</CoordinatorLayout>
also refer this link https://guides.codepath.com/android/Handling-Scrolls-with-CoordinatorLayout
Try this
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/htab_viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</RelativeLayout>
Hope this will helps you

I'm having this problem where I have a recyclerview inside a nestedscrollview, but the nestedscrollview doesn't scroll the recyclerview.
Here is a gif of the situation:
The recyclerview clearly has more children, but nestedscrollview won't scroll to them.

Add this to your recycler view xml
android:nestedScrollingEnabled="true"
Or the same can be done programatically
recyclerView.setNestedScrollingEnabled(true);
So I've got a fragment with a CoordinatorLayout as follows:

This is the layout for my MainActivity:

<!--This will be replaced with fragments-->
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"

android:fitsSystemWindows="true"
app:menu="#menu/sidenav_menu"
app:headerLayout="#layout/navigation_header">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
The fragment gets added using the FragmentManager to replace the FrameLayout. However, when I scroll up on the CoordinatorLayout, the title on my ActionBar isn't centered vertically. This is what happens:
How do I get the action bar title to center? Thanks!
EDIT: Sorry about the huge images
Just use android:paddingBottom="10dp" inside your toolbar.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"

Appbar behaviour works only if the content view has a RecyclerView or any other View capable of nested scrolling such as NestedScrollView.
I'm trying to implement the CoordinatorLayout into my App.
I tried many different tutorials and I also tried to adapt the solution on CoordinatorLayout + AppBarLayout + NavigationDrawer for my problem but I couldn't figure out why it's not working.

The coordinator itself seems to be working since I can get the effect but only when "scrolling" the upper part of the screen with the ToolBar. It doesn't work for my ScrollView in my Fragment below the ToolBar.
What am I doing wrong?
It doesn't work for my ScrollView in my Fragment
The CoordinatorLayout can listen only nested scroll. Use NestedScrollView or RecyclerView as root View in each fragment which you will add into your Activity and the CoordinatorLayout will receive scroll events.
Like so:
Your activity.xml
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

I'm trying to implement a recycler view with a collapsing toolbar layout. I have followed this tutorial, but so far my RecyclerView does not show up. All the other views are visible, though.

The progress bar and the error textview do show up when I toggle them from the code, but the recycler view won't show up.
set recyclerview to actual dp height. It worked for me.
