CollapsingToolbarLayout 不滚动

Question

I've looked through similar questions on SO and also the docs. I can't seem to figure out why this isn't working. The CollapsingToolbar doesn't collapse. The recyclerview slides underneath it when scrolling it up the screen. Any suggestions are appreciated.

Note: I've tried adding the

        app:layout_behavior="@string/appbar_scrolling_view_behavior"

to the recyclerview instead of the SwipeRefreshLayout and also have tried removing the SwipeRefreshLayout altogether.

Below is my layout file.

<?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:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">

                android:background="@drawable/logo"
                android:scaleType="centerCrop"
                app:layout_collapseMode="parallax" />

            <android.support.v7.widget.Toolbar

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

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

    <android.support.v4.widget.SwipeRefreshLayout
        android:id="@+id/swipe_refresh_layout"

            android:paddingBottom="28dp"
            android:paddingLeft="@dimen/list_side_margin"
            android:paddingRight="@dimen/list_side_margin"
            android:scrollbarStyle="outsideOverlay" />
    </android.support.v4.widget.SwipeRefreshLayout>

    <android.support.design.widget.FloatingActionButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_margin="16dp"
        android:src="@drawable/ic_add_white"
        app:layout_anchor="@id/recycler_view"
        app:layout_anchorGravity="bottom|right|end" />

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

Answer 1

不要设置 recycler.isNestedScrollingEnabled = false

Answer 2

The answer is to add

app:layout_scrollFlags="scroll|exitUntilCollapsed

to the Toolbar. Having it in the CollapsingToolbarLayout isn't enough.

Answer 3

将 android:nestedScrollingEnabled="false" 添加到您的回收站视图
