CoordinatorLayout with scrollable Toolbar

I have an Activity with an CoordinatorLayout and a Toolbar at the top of the page. I add ListFragments programmatically. In the Fragment I also have an FloatingActionButton because the FAB is for each ListFragment a different.
I add to the Toolbar etc. support for a scrollable Toolbar - If I scroll the ListView to the top I want that the Toolbar fade out. But - it doesn't. I only can move by touch or in the emulator by mouse the toolbar if I click (but not release) it. The next problem with this is. If I add the layout_scrollFlags and the layout_behavior then the FAB and the ListView are on the bottom behind the NavigationBar. If I remove it and add a android:paddingTop="?attr/actionBarSize" to the FrameLayout (only then I can see the toolbar) at the bottom everything is nice - the FAB and the ListView ends at the top of the NavigationBar - but of course the toolbar doesn't scroll. On my mobile phone without NavigationBar this things are under the end of the display - I only can see about one third of the FAB and the last row of the ListView.
So - how can I make the toolbar scrollable and to the same time the FAB and ListView are not behind the NavigationBar?

FloatingActionButton appearing under screen when using TabLayout and ViewPager

Take a look at the FAB below:
It's not appearing unless I collapse the Toolbar. Here's my XML:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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:layout_alignParentStart="true"
android:layout_below="#+id/toolbar"
android:layout_marginTop="0dp"
android:animateLayoutChanges="true"
android:background="#android:color/white"
android:layoutDirection="locale"
android:orientation="vertical"
android:padding="0dp">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/cLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#color/accent"
android:src="#drawable/ic_add"
app:layout_anchor="#id/list"
app:layout_anchorGravity="bottom|end" />
</android.support.design.widget.CoordinatorLayout>
</RelativeLayout>
Why is this happening if I set no behavior for the FAB? Is there any property I should add to anything so I could prevent this behaviour?

Simply remove your FloatingActionButton from each Fragment and add it to your Activity. This way not only the FAB stays in place but it also fixes your problem. Then you can use getActivity().findViewByIf(id) in your Fragment and set an onClickListener in each Fragment.

I suggest you remove your RelativeLayout and restructure your layout like this:
<android.support.design.widget.CoordinatorLayout
android:id="#+id/cLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/app_bar_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
</android.support.design.widget.AppBarLayout>
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#color/accent"
android:src="#drawable/ic_add"
app:layout_anchor="#id/list"
app:layout_anchorGravity="bottom|end" />
<com.rey.material.widget.ProgressView
android:id="#+id/progress_bar"
android:layout_width="60dp"
android:layout_height="60dp"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
app:pv_autostart="true"
app:pv_circular="true"
app:pv_progressMode="indeterminate"
app:pv_progressStyle="#style/Material.Drawable.CircularProgress" />
</android.support.design.widget.CoordinatorLayout>

Coordinator layout does not behave like relative layout, you can not have multiple children without disturbing each other. so just make one child of coordinator layout i.e relative layout and inside it add recyclerView and floatingActionButton
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
<android.support.v7.widget.RecyclerView
android:id="#+id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="0dp" />
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="5dp"
android:background="#color/accent"
android:src="#drawable/ic_add"
app:layout_anchor="#id/list"
app:layout_anchorGravity="bottom|end" /></RelativeLayout>

Android Nested Scrollview not scrolling

I am having a Nested ScrollView which contains contents inside a Linear Layout.

Here is my screenshots,
Initial View
When view is scrolled up, it scrolls only to hide the top navigation bar. Its not scrolling to display the items below the tab bar,

app:layout_behavior="..." should be set on a direct child of CoordinatorLayout. If your ViewPager is a direct child of CoordinatorLayout, place it to ViewPager declaration.

Quote from here: Troubleshooting Coordinator Layouts
When coordinating between a fragment with a list of items inside of a ViewPager and a parent activity, you want to put the app:layout_behavior property on the ViewPager as outlined here so the scrolls within the pager are bubbled up and can be managed by the CoordinatorLayout. Note that you should not put that app:layout_behavior property anywhere within the fragment or the list within.

You can try this! I had the same problem with my app. This worked for me.

try this
scroll.setOnTouchListener(new View.OnTouchListener() {
#Override
public boolean onTouch(View v, MotionEvent event) {
v.getParent().requestDisallowInterceptTouchEvent(true);
return false;
}
});

The ScrollingViewBehavior is just add top and bottom offset to your ViewPager. Generally the offset depends on AppBarLayout height and it do not depends on your TabLayout height because it is not in the AppBarLayout. So, for quick workaround you can just add paddingBottom to your ViewPager like this:
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="50dp"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_gravity="bottom"
android:background="#android:color/black"
android:layout_width="match_parent"
android:layout_height="50dp"/>

So here is the problem, you cannot have a NestedScrollView within the FrameLayout.
Also, some other smaller changes needed in xml to make it work.
Like the TabLayout has to be inside AppBar Layout and be pinned.
Here's your code -->
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="#+id/tabs"
android:layout_gravity="bottom"
android:background="#color/offwhite"
android:layout_width="match_parent"
app:layout_collapseMode="pin"
app:layout_anchor="#+id/appbar"
app:layout_anchorGravity="bottom"
android:layout_height="wrap_content"/>
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
And --> Change your Fragment code to remove the frame layout!
<android.support.v4.widget.NestedScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:CoverFlowPager="http://schemas.android.com/apk/res-auto"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginTop="10dp"
android:clipToPadding="false"
android:fillViewport="true">
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
Hope this helps!

AppBarLayout inside ViewPager with scrolling behavior

is there a way to put an AppBarLayout inside a ViewPager and get the scrolling behavior working? Background is that I want a header on the first fragment which scrolls out of the screen when the user scrolls down. All other fragments in the ViewPager have no header. My efforts are not successful so far, because the header doesn't scroll. Outside the ViewPager the scrolling workings fine.
I appreciate your help.

From Android Document AppBarLayout
https://developer.android.com/reference/android/support/design/widget/AppBarLayout.html
This view depends heavily on being used as a direct child within a CoordinatorLayout. If you use AppBarLayout within a different ViewGroup, most of it's functionality will not work.
Try placing your AppBarlLayout in a CoordinatorLayout .

This is actual FAB layout.
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.design.widget.FloatingActionButton
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="end|bottom"
android:clickable="true"
android:src="#drawable/cart"
android:layout_margin="20dp"
app:elevation="6dp" />
</FrameLayout>
This FAB is displaying in top right in layout. I want to display it on bottom right.
Can anyone help me on this?

Include your FAB layout in your parent layout giving layout_alignParentBottom property true:
<include layout="#layout/activity_dialog"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"/>
Also try to change CoordinatorLayout android:layout_height="fill_parent"
:
<android.support.design.widget.CoordinatorLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:id="#+id/coordinatorLayout"
android:orientation="vertical">

Remove the <include> tag.
Place your FAB in its place with the <anchor> tag:
app:layout_anchorGravity="bottom|right|end"
<android.support.design.widget.FloatingActionButton
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:layout_anchorGravity="bottom|right|end"
android:clickable="true"
android:src="#drawable/cart"
android:layout_margin="20dp"
app:elevation="6dp" />
If you still aren't winning, revise your layout by referring to this: FAB in the corner.
