Свертывание панели инструментов и вложенное scrollview не прокручивается плавно

Ответ 1

Сделать прямой дочерний элемент вложенного scrollview clickable (если у вас нет только одного дочернего элемента, добавьте макет и поместите в него все элементы пользовательского интерфейса и сделайте макет кликабельным)
андроид: clickable = "true"
Я столкнулся с подобной проблемой, и это сработало для меня!

Вот код, над которым я работал -

<?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/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="test.testrecycler.MaterialActivity"
>

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="300dp"
    android:theme="@style/AppTheme.AppBarOverlay"
    android:fitsSystemWindows="true"
    >
    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:contentScrim="?attr/colorPrimary"
        app:layout_scrollFlags="scroll|exitUntilCollapsed"
        app:expandedTitleTextAppearance="@style/expandedappbar"
        app:collapsedTitleTextAppearance="@style/collapsedappbar"
        app:statusBarScrim="@color/colorPrimaryDark"
        >
        <ImageView
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/sample"
            android:scaleType="centerCrop"
            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_collapseMode="pin" />

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

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

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

И вот файл content_material.xml, имеющий NestedScrollView.It имеет один дочерний элемент (TextView), который был сделан кликабельным.

    the required standard. Three seasons later the team won the title again and this time gained promotion to the Conference, where they spent
    nine seasons before being relegated. The club was transferred to the Isthmian League Premier Division in 2004, but another poor season led
    the club to a further relegation. After three seasons in the Isthmian League Division One South, the club won the championship and promotion
    back to the Premier Division, and the following season won another championship and promotion to Conference South. In the 2013–14 season,
    Dover defeated Ebbsfleet United to return to the Conference Premier after a twelve-year absence. Nicknamed the Whites for their white shirts,
    they have played at the Crabble Athletic Ground since the club formation. Their best performance in the FA Cup was reaching the third

ОБНОВЛЕНИЕ: Вы можете уменьшить размер изображения, просто щелкнув правой кнопкой мыши по изображению в ANDROID STUDIO и Конвертировать изображение в webp. Это резко уменьшит размер изображения

Это очень просто. Я много боролся и, наконец, узнал, что это проблема с изображением высокого разрешения, которое я поместил в src ImageView. Решение: Просто уменьшите разрешение изображения, сохранив его размеры. (Возможно, с помощью Photoshop).

Я думаю, что вы забываете закрыть тег для CoordinatorLayout. Кроме того, поместите панель инструментов на CollapsingToolbarLayout

Ответ 4

У меня возникли аналогичные проблемы с макетом, содержащим coordinator layout и фрагменты, содержащие RecyclerView. Я добавил следующий код в CollapsingToolbarLayout, чтобы сделать прокрутку гладкой.

app:layout_scrollFlags="scroll|enterAlways"

Ответ 5

Плавная прокрутка CoordinatorLayout и CollapsingToolbarLayout является ошибкой, и Google до сих пор не исправил ее. : |

удалить NestedScrollView. RecyclerView с приложением: layout_behavior = "@string/appbar_scrolling_view_behavior" Это достаточно и исправить.

Вы можете использовать стороннюю библиотеку: https://github.com/henrytao-me/smooth-app-bar-layout

Ответ 6

Если вы добавили флаги прокрутки на панель инструментов, просто удалите. Это все
