Android RecyclerView avec CollapsingToolbarLayout problème de défilement lisse

Question

Je veux utiliser CollapsingToolbarLayout avec RecyclerView comme Whatsapp .

Voici la vidéo capturée : https://sendvid.com/0oi2lxx5

Donc quand je fais défiler vers le haut, ça va, mais quand je fais défiler vers le bas, ce n'est pas fluide. Je veux le faire défiler en douceur avec RecyclerView .

Voici donc mon 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>

J'utilise :

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'

Comment puis-je réparer cela ?

Answer 1

Je vais vous expliquer comment résoudre ce problème, maintenant ma mise en page est super fluide ;

En fait, je ne sais pas comment c'est résolu, mais.. ;

• J'ai tout effacé. android:fitsSystemWindows="true" attributs.
• puis a ajouté app:layout_scrollFlags="scroll|enterAlways" à l'attribut CollapsingToolbarLayout , ImageView et Toolbar .
• Et j'ai déplacé tous les éléments avant mon AppBarLayout en xml.

Mon activity_profile.xml comme :

<?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>

Et le content_profile_edit.xml comme :

<?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

J'ai eu des problèmes avec RecyclerView et CollapsingToolbarLayout également (ne s'est pas effondré du tout). Essayez d'utiliser la version actuelle 23.4.+ de recyclerview, appcompat et design si vous ne le faites pas déjà.
