具有CollapsingToolbarLayout的Android RecyclerView平滑滚动问题

标签： android android-recyclerview android-collapsingtoolbarlayout nestedscrollview

我想将CollapsingToolbarLayout与RecyclerView一起使用，例如Whatsapp。

以下是捕获的视频：https://sendvid.com/0oi2lxx5

所以当我向上滚动它没关系，但当我向下滚动时它不顺畅。我想用RecyclerView顺利滚动它。

所以这是我的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>

我正在使用：

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'

我该如何解决这个问题？

我会解释如何解决问题，现在我的布局非常流畅;

  

其实我不知道它是如何解决的，但是;

  • 我删除了所有android:fitsSystemWindows="true"属性。
  • 然后将app:layout_scrollFlags="scroll|enterAlways"属性添加到CollapsingToolbarLayout，ImageView和Toolbar。
  • 并将所有元素移到我的AppBarLayout xml。
    • 之前

我也遇到了RecyclerView和CollapsingToolbarLayout的问题（根本没有崩溃）。如果你还没有使用，请尝试使用当前版本的23.4。+ recyclelerview，appcompat和design。
