其实我正在尝试构建一个listView / recyclerView。在滚动列表时,操作栏得到隐藏,其中操作栏是工具栏,但列表视图的某些部分隐藏在选项卡后面。这里我使用AppBarLayout和工具栏有app:layout_scrollFlags =“scroll | enterAlways”,在我的recylerview中有app:layout_behavior =“@ string / appbar_scrolling_view_behavior”行为。我可以使用线性布局,但问题是工具栏的滑动,AppBarLayout必须是CoordinatorLayout的子项。
我的活动有xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:paddingTop="50dp">

android:clickable="true"
android:src="@drawable/ic_dialpad_white"
app:layout_anchor="@id/pager"
app:layout_anchorGravity="bottom|center" />
</android.support.design.widget.CoordinatorLayout>
和我的片段
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout
android:id="@+id/main_content"
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/white">
<android.support.v7.widget.RecyclerView
android:id="@+id/recentcall_recyclerview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="vertical"
app:layout_behavior="@string/appbar_scrolling_view_behavior"
/>
</android.support.design.widget.CoordinatorLayout>
我在滑动列表视图时使工具栏滑动时出错了,或者在不使用任何第三个库的情况下有另一种方法。

试试这个:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:popupTheme="@style/Theme.AppCompat.Light.DarkActionBar"
app:theme="@style/Toolbar">
<android.support.v7.widget.Toolbar
android:id="@+id/action_bars"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
/>
<ameyo.genie.SlidingTabLayout
android:id="@+id/sliding_tabs"
android:layout_width="match_parent"
android:layout_height="48dp"
android:background="@color/colorPrimary"
/>
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingTop="50dp">
<android.support.v4.view.ViewPager
android:id="@+id/pager"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</FrameLayout>
</android.support.design.widget.AppBarLayout>
当您放置组件时,按位置排序,如果没有空格,每个组件都将超过先例!

感谢Daniel Nugent,我忘了写android:layout_below="@+id/sliding_tabs
&#34;在viewpager里面也删除了framelayout和height必须是wrapcontent现在我的最终代码是这个正在工作
