I have an activity with a coordinator layout as a parent, the activity is composed of a toolbar and viewpager tablayout. The activity has a fragment with a relative layout parent and nested in this relative layout is a recyclerview and a bottom sheet.
Now the problem is that the bottom sheet does not work well with the relative layout but the toolbar scrolls well on recyclerview scroll event.
However, when I use a coordinator layout as the parent of the fragment layout, the bottom sheet works fine but the tab fails to scroll hence the bottom sheet is not fully shown.
My question: How can I use bootomsheet in a relativelayout parent. Or can I still use Coordinator layout in the fragment and the parent tab still scrolls well?
Here is the code for the fragment with the relative layout as root layout:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"

I expect the toolbar to scroll out of view when scrolling down the recylerview items and scroll into view when scrolling up the recyclerview items.
You can check the doc:
BottomSheetBehavior is applied to a child of CoordinatorLayout to make that child a persistent bottom sheet.
BottomSheetBehavior works in tandem with CoordinatorLayout to let you display content on a Bottom sheet.

In fragment section there is another layout with SwipeRefreshLayout (containing RecyclerView) and FloatingActionButton.
What I get
As you can see on picture first items of recycler view goes under toolbar.
If I add such string to Relative layout of fragment:
app:layout_behavior="#string/appbar_scrolling_view_behavior"
recycler view starts "to see" toolbar and moves down to its height:
Result
BUT, as you can see recycler view saved its height and moved out of screen.
I want: recycler adjusts its height. I want it to be always connected with bottom edge and growing when toolbar is hidden.
I made a layout using CoordinatorLayout as a container and NestedScrollView to display my contents.
I used NestedScrollView to hide my toolbar when scrolling down, but the usual wave effect which should be shown below toolbar whenever I try to scroll and reach the limit of the layout is not working.
Here is the
.
How to make this effect? If I use normal ScrollView, this effect will be shown but I can not hide my toolbar.
Here is my layout:
<android.support.design.widget.CoordinatorLayout

app:title="Detail"
app:titleTextAppearance="#style/ToolbarTheme.TitleText"/>
</android.support.design.widget.AppBarLayout>
<include layout="#layout/activity_detail_content"/>
</android.support.design.widget.CoordinatorLayout>
And here is my detail content:
<android.support.v4.widget.NestedScrollView

app:layout_behavior="#string/appbar_scrolling_view_behavior">
//contents
//contents

Try this:
android:clipToPadding="false"
In your NestedScollView.
View pager ScreenShot
Vertical View Pager
First Fragment
Second Fragment
Collapsing Toolbar
Image View
Tab Layout
View Pager
Grid Fragment
Second Fragment
Recycler View(Main)
Recycler View
Map Fragment
When i scroll (Main)recycler view Collapsing toolbar should expand and collapse and after vertical view pager should scroll.
But in my code (main)Recycler view not scrolling properly and collapsing toolbar not working properly.

wrap your viewpager inside a NestedScrollView instead of a LinearLayout and then set the layout_behavior to appbar_scrolling_view for both the NestedScrollView and the ViewPager. Took me forever but I found that this worked for me.
<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">
<com.example.ashleighwilson.schoolscheduler.views.CustomViewPager
android:id="#+id/viewpager"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior">
</com.example.ashleighwilson.schoolscheduler.views.CustomViewPager>
</android.support.v4.widget.NestedScrollView>
also be sure to set fillViewport to true in the NestedScrollView and make sure the width and height is set to match parent. This is important.
I have 3 views in my layout file with CoordinatorLayout as the root view : AppbarLayout, RecyclerView and a Footer(not visible all the time). Recyclerview implements the default behavior appbar_scrolling_view_behavior, that ideally, brings recyclerview below the appbarlayout. But the recyclerview and footer overlap. To Prevent that, I had to write a custom behavior so that when footer is visible, Recyclerview should make space for the footer. But now, the default behavior of appbar_scrolling_view_behavior is gone and now appbarlayout and recyclerview overlap.Here is the Image of the layout
Link to the custom behavior i implemented:
https://github.com/Mandeep221/CustomBehaviorForRecyclerview/blob/master/CustomBehavior.java
My Question: How can i implement 2 things(simultaneously in one behavior):
get the recyclerview below the appbarlayout inside the co-ordinatorlayout
get the recycelerview to make space for the footer if the footer is visible.
If you can suggest some workaround, that would also be great! Thanks alot!

Don't keep the android.support.design.widget.CoordinatorLayout as root layout.
Add a RelativeLayout as a root layout. Then add android.support.design.widget.CoordinatorLayout with property layout_alignParentTop and layout_above="#+id/footerBar" and set prokure.it.prokure.FooterBarLayout as align parent bottom as second child of RelativeLayout.

Another simpler way is to add following lines to your prokure.it.prokure.FooterBarLayout
app:layout_anchor="#id/list_recycler_view"
app:layout_anchorGravity="bottom"
and keep prokure.it.prokure.FooterBarLayout inside coordinator layout.
Make sure to add an empty cell at the end of the recycler view so that prokure.it.prokure.FooterBarLayout does not overlap with last cell of RecyclerView.
I recently started messing around with the new components of AppCompat 21 and implementing Material Design. Currently, I have an ActionBarActivity with a Toolbar and am trying to have it host a fragment containing a RecyclerView of TextView items (just to test out Recycler). I have items being displayed, but the text in each view is cut off and the entire Recycler is covering the Toolbar like so:
As you can see, there are three TextViews. Their text is cut off halfway and it's overlaying the Toolbar (no Title I know). The TextView item layouts are contained within a RecyclerView layout, which is the layout of the Fragment. The parent Activity has a FrameLayout -> Toolbar, FrameLayout. I am inserting the Fragment into the Activity's sub FrameLayout. Here's the XML:
Each view in the Recycler:
<TextView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/textview"
android:layout_width="match_parent"
android:layout_height="48dp"
android:fontFamily="sans-serif"
android:paddingTop="16dp"
android:paddingBottom="20dp"
android:textSize="16sp"/>
The Recycler layout, which is the layout of the Fragment:
<android.support.v7.widget.RecyclerView
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/recycler_tasks"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="stuff.MainActivity$TaskFragment">
</android.support.v7.widget.RecyclerView>
And the parent Activity's layout:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity"
tools:ignore="MergeRootFrame">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:minHeight="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light"/>
<FrameLayout
android:id="#+id/fragment_container"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</FrameLayout>
I know it must be something simple but I've been stumped on it for a while, trying various things to no avail.
Please do not forget to add app:layout_behavior="#string/appbar_scrolling_view_behavior" to your content layout
<android.support.design.widget.CoordinatorLayout
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.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/ThemeOverlay.AppCompat.Dark.ActionBar">
<android.support.v7.widget.Toolbar
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
<android.support.design.widget.TabLayout
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
Use RelativeLayout instead of FrameLayout as top parent. Then just add dependencies like layout_above for the Toolbar or layout_below for the fragment container.
