如何将 RecyclerView 与 CollapsingToolbarLayout 结合使用。 RecyclerView 需要在到达底部时加载更多数据

Question

我的问题是，我想将 RecyclerView 与 CollapsingToolbarLayout 一起使用。但问题是 CollapsingToolbarLayout 在 RecyclerView 滚动时不滚动。我不能使用嵌套滚动来放置 RecyclerView，因为我想加载更多数据到 RecyclerView

<android.support.design.widget.AppBarLayout
    android:id="@+id/collapsing_toolbar_appbarlayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="?themeColorBack">

    <android.support.design.widget.CollapsingToolbarLayout
        android:id="@+id/collapsing_toolbar_layout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:contentScrim="?themeColorBack"

            <RelativeLayout

                    android:orientation="vertical">

                    <TextView

        </LinearLayout>

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


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

<!-- app:layout_behavior attribute value settings make app tool bar appear while RecyclerView scroll. -->
<android.support.v7.widget.RecyclerView

你可以这样使用。

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/myCoordinatorLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:fitsSystemWindows="true">

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

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

        <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_margin="4dp" />
    </LinearLayout>

    <com.google.android.material.floatingactionbutton.FloatingActionButton
        android:id="@+id/fab"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="end|bottom"
        android:layout_margin="18dp"
        android:src="@drawable/ic_add" />
</androidx.coordinatorlayout.widget.CoordinatorLayout>
