尝试使用新的支持设计库。在我的布局中，我希望ToolBar保持在屏幕顶部，但TabLayout在用户向下滚动时离开屏幕。但它看起来像ViewPager在AppBarLayout. 我使用这篇博文作为参考 https://medium.com/ribot-labs/exploring-the-new-android-design-support-library-b7cda56d2c32

这是布局，ViewPager包含Fragments在回收站视图中

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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/material_grey50"
android:clickable="true">

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

    <android.support.v4.view.ViewPager
        android:id="@+id/pager"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/tabLayout" />


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


    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar_list"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="?attr/colorPrimary"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />


    <android.support.design.widget.TabLayout
        android:id="@+id/tabLayout"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/toolbar_list"
        android:background="?attr/colorPrimary"
        android:scrollbars="horizontal"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:layout_scrollFlags="scroll|enterAlways"
        app:tabGravity="center" />


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


<android.support.design.widget.FloatingActionButton
    android:id="@+id/fab_post"
    android:layout_width="wrap_content"

    android:elevation="3dp"
    android:src="@drawable/ic_videocam_white_36dp"
    app:backgroundTint="@color/accent"
    app:fabSize="normal" />

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

不要忘记在 viewpager 中设置它：

app:layout_behavior="@string/appbar_scrolling_view_behavior"
