I've been playing around with the Design Support Library and have come across a little problem that I hope someone can help me out with.
I'm using a CollapsingToolbar which contain an ImageView which collapses in parralax. In the CollapsingToolbar, I alse have a TabLayout which is supposed to scroll my ViewPager. My issue is that the ViewPager doesn't appear. The issue seems to arise only when I set my ViewPager layout_height to match_parent or wrap_content. If I set it to 600dp, then the problem is gone but then the view ends up being a fixed length which isn't very nice.
Any help would be grealty appreciated!
Here's my XML
<android.support.design.widget.CoordinatorLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"

android:layout_width="match_parent"
android:layout_height="match_parent"

app:layout_behavior="#string/appbar_scrolling_view_behavior"
/>
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
You should remove the NestedScrollView and LinearLayout levels between your CoordinatorLayout and ViewPager:
<android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.AppBarLayout>
...
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
The view with app:layout_behavior="#string/appbar_scrolling_view_behavior must be a direct child of CoordinatorLayout to be positioned correctly in relation to the AppBarLayout.

I am trying to implement the parallax effect with for my layout.
It works, however I need one more thing.
Here is my code

This works fine, however I am only able to scroll/collapse toolber while swiping the header ImageView (image_view_tab_header). When I try to swipe up inside the ViewPager it doesn't collapse toolbar. Only when I try to swipe up inside the header itself.
How can I enable collapsing of toolbar when swiping inside the viewpager ?
Thanks
Try the following by including ViewPager inside NestedScrollView
<android.support.v4.widget.NestedScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
<android.support.v4.view.ViewPager
android:id="#+id/view_pager_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</android.support.v4.widget.NestedScrollView>
Im trying to create an AppBarLayout using the CollapsingToolBar which contains a Toolbar and a TabLayout and im also using the app:behavior_overlapTop attribute on my RelativeLayout which includes a ViewPager. The problem is that when the CollapsingToolBar is expanded my TabLayout disappears behind the ViewPager as the TabLayout is given a layout_gravity = bottom and due to the fact that i have used app:behavior_overlapTop on my RelativeLayout which includes the ViewPager. How can i fix this ? Thanx in advance.
( This is my first question here, sorry if have missed anything, i would have included images for better understanding of the problem but i dont have enough repo )

I am trying to pin the tablayout on top while scrolling. It doesn't work. More important point is, there is a listview in each viewpager fragment and the listview scrolling doesn't work in the listview.
Can anybody help
You need to use NestedScrollView, provided in Android Support Library v4, which is designed to work with CoordinatorLayout
<android.support.v4.widget.NestedScrollView ...>
<LinearLayout ...>
...
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
or RecyclerView, please note that the classic ListView doesn't work with CoordinatorLayout.
so inside your viewPager you need to have NestedScrollView or RecyclerView
Good luck
I am using Support Design Library rev. 23.0.1 (and 22.2.1 as well). The problem is after activity orientation changes if RecyclerView (placed in fragment) has been scrolled, it loses its top padding which is probably equal to StatusBar Height + AppBar Height (as you see on a picture).
See this sample video for details
Here is my Activity layout
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinatorLayout"
android:layout_width="match_parent"

And a simple fragment contains RecyclerView
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context="com.moskart.mosfake.fragment.DiscountFeedFragment"
>
<com.moskart.mosfake.widget.GridRecyclerView
android:id="#+id/recycler_view_discount_feed"
android:layout_width="match_parent"
android:layout_height="match_parent"
/>
By the way, I found some following issues, but these answers doesn't solve my problem. I've also tried approaches described here and here, but it has no effect, or I doing something wrong.
Thanks for your help!
I made an activity where image should collapse with toolbar and only text below would be visible. But When Toolbar being collapsed, there shows up a large gap between Toolbar and NestedScrollView
<android.support.design.widget.CoordinatorLayout xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/coordinatorLayout"
android:layout_width="match_parent"
android:background="#color/white"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/appBarLayout"
android:layout_width="match_parent"
app:elevation="5dp"
app:layout_collapseMode="pin"
android:fitsSystemWindows="true"
android:layout_height="wrap_content">
<android.support.design.widget.CollapsingToolbarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:toolbarId="#+id/toolbar"
android:id="#+id/collapsing"
android:fitsSystemWindows="true"
app:contentScrim="?attr/colorPrimary"
app:layout_scrollFlags="scroll|exitUntilCollapsed">
<com.noframe.farmisagronom.util.ResizibleImageView
android:id="#+id/image_view"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:layout_scrollFlags="scroll|enterAlwaysCollapsed"
android:minHeight="100dp"
android:maxHeight="400dp"
android:fitsSystemWindows="true"
app:layout_collapseMode="parallax"
app:layout_collapseParallaxMultiplier="0.5"
android:scaleType="centerCrop"/>
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:popupTheme="#style/ThemeOverlay.AppCompat.Light"
android:minHeight="?attr/actionBarSize"
app:layout_collapseMode="pin"
/>
</android.support.design.widget.CollapsingToolbarLayout>
</android.support.design.widget.AppBarLayout>
<android.support.v4.widget.NestedScrollView
android:id="#+id/nesteview"
app:layout_anchorGravity="top"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
.....
</android.support.v4.widget.NestedScrollView>
</android.support.design.widget.CoordinatorLayout>
And this activity looks really good.
But when i scroll up the NestedScrollView this goes out of control.
This little space between toolbar and text is getting on my nerves.
note that if there is large text in NestedScrollView problem won't show up, but if NestedScrollView + collapsed tool bar doesn't take all phone screen, then there is a gap between them.
Adding:
android:layout_gravity="fill_vertical"
to the NestedScrollView worked for me.
