Android RecyclerView with CollapsingToolbarLayout smooth scroll issue

Question

I want to use CollapsingToolbarLayoutwith RecyclerView, like Whatsapp.

Here is the captured video : https://sendvid.com/0oi2lxx5

So when I scroll up it's okay, but when I scroll down it's not smooth. I want to scroll it smoothly with RecyclerView.

So here is my profile_activity.xml:

    <?xml version="1.0" encoding="utf-8"?>
    <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:fitsSystemWindows="true">
    <android.support.v7.widget.RecyclerView
        android:layout_width="match_parent"
        android:id="@+id/profile_recyclerview"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        android:layout_below="@+id/profileactivity_appbar" />

    <android.support.design.widget.AppBarLayout
        android:id="@+id/profileactivity_appbar"
        android:layout_width="match_parent"
        android:layout_height="400dp"
        android:fitsSystemWindows="true"
        android:theme="@style/AppTheme3.AppBarOverlay">

        <android.support.design.widget.CollapsingToolbarLayout
            android:id="@+id/profileactivity_collapsing_toolbar"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_scrollFlags="scroll|exitUntilCollapsed"
            android:fitsSystemWindows="true"
            app:contentScrim="?attr/colorPrimary"
            app:expandedTitleMarginStart="48dp"
            app:expandedTitleMarginEnd="64dp">

            <ImageView
                android:id="@+id/profileactivity_fullimage"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:scaleType="centerCrop"
                android:fitsSystemWindows="true"
                app:layout_collapseMode="parallax"
                app:layout_scrollFlags="scroll|enterAlways|enterAlwaysCollapsed" />

            <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"
                app:layout_collapseMode="pin" />

        </android.support.design.widget.CollapsingToolbarLayout>

    </android.support.design.widget.AppBarLayout>




    <android.support.design.widget.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="@dimen/fab_margin"
        app:layout_anchor="@id/profileactivity_appbar"
        app:layout_anchorGravity="bottom|right|end"
        app:backgroundTint="@color/ColorPrimary"
        android:src="@drawable/ic_create_white_48dp"/>

</android.support.design.widget.CoordinatorLayout>

I am using:

compile 'com.android.support:appcompat-v7:23.4.0'
compile 'com.android.support:support-v4:23.4.0'
compile 'com.android.support:recyclerview-v7:23.4.0'
compile 'com.android.support:design:23.4.0'

How can I fix this?

Answer 1

Well i will explain how to solve issue , now my layout is super smooth ;

Actually i dont know how its solved , but ;

• i deleted all android:fitsSystemWindows="true" attributes.
• then added app:layout_scrollFlags="scroll|enterAlways" attribute to CollapsingToolbarLayout , ImageView and Toolbar.
• And moved all elements before my AppBarLayout in xml.

My activity_profile.xml like :

<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/apk/res-auto"
    android:id="@+id/profileCoordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<ProgressBar android:indeterminate="true"
    android:layout_width="50dp" android:layout_height="50dp"
    android:id="@+id/profile_activity_progress" 
    style="?android:attr/progressBarStyle"
    android:layout_gravity="center_vertical|center_horizontal"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true"
    android:visibility="visible" />

<ProgressBar android:indeterminate="true"
    android:layout_width="50dp" android:layout_height="50dp"
    android:id="@+id/profile_activity_progress_edit" 
    style="?android:attr/progressBarStyle"
    android:layout_gravity="center_vertical|center_horizontal"
    android:visibility="gone" />


<include layout="@layout/content_profile_edit"/>


<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/profile_recyclerview"
    app:layout_behavior="@string/appbar_scrolling_view_behavior" />

<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:visibility="gone"
    android:layout_margin="@dimen/fab_margin"
    app:layout_anchor="@+id/profileactivity_appbar"
    app:layout_anchorGravity="bottom|right|end"
    app:backgroundTint="@color/ColorPrimary"
    android:src="@drawable/ic_create_white_48dp"/>

<android.support.design.widget.AppBarLayout
    android:id="@+id/profileactivity_appbar"
    android:layout_width="match_parent"
    android:layout_height="400dp"
    android:visibility="gone"
    android:theme="@style/AppTheme3.AppBarOverlay">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/profileactivity_collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_scrollFlags="scroll|enterAlways"
        app:statusBarScrim="@color/ColorPrimaryDark"
        app:contentScrim="?attr/colorPrimary"
        app:expandedTitleMarginStart="48dp"
        app:expandedTitleMarginEnd="64dp">

        <ImageView
            android:id="@+id/profileactivity_fullimage"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:scaleType="centerCrop"
            app:layout_scrollFlags="scroll|enterAlways"
            app:layout_collapseMode="parallax" />

        <android.support.v7.widget.Toolbar
            android:id="@+id/toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            app:layout_scrollFlags="scroll|enterAlways"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_collapseMode="pin" />

    </android.support.design.widget.CollapsingToolbarLayout>

  </android.support.design.widget.AppBarLayout>

</android.support.design.widget.CoordinatorLayout>

And the content_profile_edit.xml like :

<?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:id="@+id/profile_edit_layout"
    android:layout_alignParentBottom="true"
    android:visibility="gone"
    app:layout_behavior="@string/appbar_scrolling_view_behavior">

<android.support.v4.widget.NestedScrollView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:id="@+id/profile_fragment_nested"
    android:layout_height="match_parent"
    android:padding="10dp">

   <!-- other views -->

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

</RelativeLayout>

Answer 2

I had problems with RecyclerView and CollapsingToolbarLayout as well (did not collapse at all). Try using the current version 23.4.+ of recyclerview, appcompat and design if you're not doing already.
