When i was burning my midnight oil this library came like batman

https://github.com/henrytao-me/smooth-app-bar-layout

According to which the behavior can be improved by following these steps:

1.Change

 android.support.design.widget.AppBarLayout

 me.henrytao.smoothappbarlayout.SmoothAppBarLayout and set android:id

2.Remove

 app:layout_behavior="@string/appbar_scrolling_view_behavior"

3.Add header to your NestedScrollView or RecyclerView

Which actually made it to work like charm.

The final setup looks like

                <android.support.design.widget.CoordinatorLayout 
                 xmlns:android="http://schemas.android.com/apk/res/android"

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

                  <android.support.v4.widget.NestedScrollView
                    android:id="@+id/nested_scroll_view"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent">

                    <LinearLayout
                      android:layout_width="match_parent"
                      android:layout_height="wrap_content"
                      android:orientation="vertical"
                      android:paddingLeft="16dp"
                      android:paddingRight="16dp"
                      android:paddingTop="@dimen/app_bar_height">

                      <TextView
                        android:layout_width="match_parent"
                        android:layout_height="wrap_content"
                        android:layout_marginBottom="16dp"
                        android:layout_marginTop="16dp"
                        android:text="@string/text_short" />

                    </LinearLayout>
                  </android.support.v4.widget.NestedScrollView>

                  <me.henrytao.smoothappbarlayout.SmoothAppBarLayout

                      app:layout_scrollFlags="scroll|exitUntilCollapsed">

                      <android.support.v7.widget.Toolbar

                        app:navigationIcon="@drawable/ic_menu_arrow_back"
                        style="@style/AppStyle.MdToolbar" />
                    </android.support.design.widget.CollapsingToolbarLayout>
                  </me.henrytao.smoothappbarlayout.SmoothAppBarLayout>
                </android.support.design.widget.CoordinatorLayout>

If you still face any issue while implementing this ask here i would love to help and mark this up if this answer helps.

Solution 2

Use support-library 26.0.1 version.

This problem has been solved by google from the support library after version 26.0.0

I am working on an application where I'm using AppBarLayout with CollapsingToolbarLayout and NestedScrollView. I have successfully implemented this and it is working fine.

Now what i am trying to do is, that on fling(fast swipe up) on the Nestedscrollview it should scroll completely to top. Similarly, on fling(fast swipe down) towards the bottom of the screen, it must scroll all the way to the bottom smoothly. However now, it only gets stuck in between which makes it look ugly. I have tried many available solutions available here but nothing worked for me. My current setup is below.

One of the most accepted answers, shown below did not work for me either.

Unable to scroll AppBarLayout and collapsing toolbar with NestedScrollView smoothly

Raphael Royer-Rivard over 7 years

I tried your solution, but when I remove the layout_behavior, the AppBar disappears... Do you know why?
Raphael Royer-Rivard over 7 years

But what do you mean in your step 2? You said to remove the layout_behavior
Harry Sharma over 7 years

Oh sorry i miss understood your question..are you using this with nestedscrollview or recyclerview...??
Raphael Royer-Rivard over 7 years

It's alright, I'm glad you even consider helping me haha. I'm using nestedscrollview
Harry Sharma over 7 years

Have you added the header..to nestedscrollview..? As i ahve mentioned..If still its unclear..go through the given sample..it works perfectly..I am sure you are missing something... :)
Raphael Royer-Rivard over 7 years

By header, you mean the paddingTop of its layout child?
Raphael Royer-Rivard over 7 years

I also noticed that in the examples of your github, I was missing the SmoothCollapsingToolbarLayout, but adding it did not make the disappeared AppBar reappear.
Harry Sharma over 7 years

Have you run the samples given at github..?? Run them without making any change...They work perfectly...If still you get problem mail me ur code at [email protected]... I will make it work... :) Happy
Raphael Royer-Rivard over 7 years

I did not... Finally I decided to create my own AppBarLayout.Behavior and apply it to the NestedScrollView. And it works perfectly :) If you are curious, you can go check it at stackoverflow.com/a/40711920/1084822
Chad Mx over 7 years

@RaphaelRoyer-Rivard Your AppBarLayout disappears because you removed app:layout_behaviour. One of the things this declaration does is to tell your coordinator layout to place your scroll view BELOW your AppBarLayout. Because you have your nestscrollview's height as match_parent, and you removed the behaviour decleration, your AppBarLayout has no room in the parent view.
Raphael Royer-Rivard over 7 years

@ChadMx Oh I see, that sounds fair. But I still don't understand why Harry Sharma is asking to remove the app:layout_behavior while he still has his NestedScrollView's height as match_parent...
Harry Sharma over 7 years

@RaphaelRoyer-Rivard coz i have implemented with my own behavior..see the working example.it works without any flaw..
Juan Mendez over 7 years

I've been even finished a tutorial related to appbarlayout/nestedscrolllayout, and I want to try the 3rd party library you mentioned. :)
Harry Sharma over 7 years

Yeah try it...it will help others too :)
Jimit Patel about 7 years

Any other solution apart from using 3rd party library?
