Here is my setup, i am running a DrawerLayout, within it is a CoordinatorLayout containing an AppBarLayout and a nestedscrollview. I am trying to have the nestedscrollview scroll normally and the Toolbar to get hidden on scrolling down and reppear on scrolling up. Attached within is my XML code. Would appreciate any help.. have read all related questions and implemented their answers without any success.

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/drawer_layout_admin"
android:layout_width="match_parent"
android:layout_height="match_parent">

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/admincoordinator"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:id="@+id/appBarLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <include
            android:id="@+id/app_bar"
            layout="@layout/app_bar"
            app:layout_scrollFlags="scroll|enterAlways" />

        <android.support.design.widget.TabLayout
            android:id="@+id/tabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </android.support.design.widget.AppBarLayout>

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

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

<android.support.design.widget.NavigationView
    android:id="@+id/nav_drawer"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    app:headerLayout="@layout/drawer_header"
    app:menu="@menu/menu_drawer" />

推荐答案

我有一个星期遇到同样的问题，并尝试了所有解决方法. 但是我设法解决了这个问题.

I have had the same issue for a week and tried almost everything to solve it. However I managed to solve the issue.

您有类似...的地方

<include
    android:id="@+id/app_bar"
    layout="@layout/app_bar"
    app:layout_scrollFlags="scroll|enterAlways" />

...将此内容替换为您的app_bar.xml布局中的任何内容.例如:

...replace this with whatever is in your app_bar.xml layout. For example:

<android.support.v7.widget.Toolbar
    android:id="@+id/main_toolbar"
    style="@style/AppTheme.Toolbar"
    android:layout_height="wrap_content"
    android:layout_width="match_parent"
    app:layout_scrollFlags="scroll|enterAlways"/>

似乎出于某些原因，使用<include>标签滚动CoordinatorLayout无效.

It seems that for some reason, scrolling with CoordinatorLayout does not work when using the <include> tag.
