与CollapsingToolbarLayout一起使用时，NestedScrollView不会滚动到末尾 [英] NestedScrollView wont't scroll to the end when used with CollapsingToolbarLayout

问题描述

我想将NestedScrollView与CollapsingToolbarLayout一起使用.在NestedScrollView中，内容确实很长.不幸的是，我无法滚动到最后.一些长篇幅的内容被删减了.当我打开屏幕，滚动正常且所有内容可见时，这很奇怪.

I want to use NestedScrollView with CollapsingToolbarLayout. In NestedScrollView there is really long content. Unfortunately I can't scroll to the end. Some of this long content is cut. What is strange when I turn screen, scrolling works fine and all content is visible.

<android.support.design.widget.CoordinatorLayout
    android:fitsSystemWindows="true"
    android:layout_height="match_parent"
    android:layout_width="match_parent">

    <android.support.design.widget.AppBarLayout
        android:fitsSystemWindows="true"
        android:layout_height="wrap_content"
        android:layout_width="match_parent">

        <android.support.design.widget.CollapsingToolbarLayout
            android:fitsSystemWindows="true"
            android:layout_height="match_parent"
            android:layout_width="match_parent"
            app:contentScrim="?attr/colorPrimary"
            app:layout_scrollFlags="scroll|exitUntilCollapsed">

            <ImageView
                android:fitsSystemWindows="true"
                android:layout_height="wrap_content"
                android:layout_width="match_parent"
                android:scaleType="centerCrop"
                android:src="@drawable/u8"
                app:layout_collapseMode="parallax"/>

            <android.support.v7.widget.Toolbar
                android:layout_height="?attr/actionBarSize"
                android:layout_width="match_parent"
                app:layout_collapseMode="pin"/>

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

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

    <android.support.v4.widget.NestedScrollView
        android:clipToPadding="false"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <LinearLayout
            android:layout_height="match_parent"
            android:layout_width="match_parent"
            android:orientation="vertical">

            <!-- lots of widgets-->

        </LinearLayout>

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

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

我注意到剪切内容的高度与工具栏的高度相同.

I noticed that height of cut content is the same as Toolbar height.

Answer taken from here. Adding paddingBottom to NestedScrollView resolved this issue for me:

android:paddingBottom="<toolbar height in collapsed state>"
