我需要在 RecyclerView 上方显示一个标题，但使用下面的代码，标题不是固定的，并且会随着回收器视图滚动。有没有人可以解决他的问题？

fragment_history_detail.xml

[[第一次尝试]] 

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?android:attr/colorBackground">

    <RelativeLayout
        android:id="@+id/header_container"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true">

        <include
            layout="@layout/view_header_history_detail"
            android:layout_width="match_parent"
            android:layout_height="wrap_content" />
    </RelativeLayout>

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/header_container">

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView_history_list"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_weight="1"
            app:layoutManager="LinearLayoutManager"
            tools:listitem="@layout/fragment_history_detail_item_self" />
    </RelativeLayout>
</RelativeLayout>

[[第二次尝试]]

我也尝试使用如下所示的 LinearLayout。但这无济于事。

<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?android:attr/colorBackground"
    android:orientation="vertical">

    <include
        layout="@layout/view_header_history_detail"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />


    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView_history_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        app:layoutManager="LinearLayoutManager"
        tools:listitem="@layout/fragment_history_detail_item_self" />

</LinearLayout>

如果你想修复布局，那么你可以按照我的想法做一件事......看看下面的代码......

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="?android:attr/colorBackground"
android:orientation="vertical">

<include
    layout="@layout/view_header_history_detail"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

<RelativeLayout xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="?android:attr/colorBackground"/>

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView_history_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        app:layoutManager="LinearLayoutManager"
        tools:listitem="@layout/fragment_history_detail_item_self" /></LinearLayout>

复制以下代码并放入您的xml文件

<RelativeLayout
    android:id="@+id/header_container"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentTop="true">

    <include
        layout="@layout/view_header_history_detail"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</RelativeLayout>
<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@id/header_container">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView_history_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        app:layoutManager="LinearLayoutManager"
        tools:listitem="@layout/fragment_history_detail_item_self" />
</RelativeLayout>

删除上面的相对布局，或者您可以粘贴相对布局内容 

<RelativeLayout
   xmlns:app="http://schemas.android.com/apk/res-auto"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:background="?android:attr/colorBackground">

    <android.support.v7.widget.RecyclerView
        android:id="@+id/recyclerView_history_list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        app:layoutManager="LinearLayoutManager"
        tools:listitem="@layout/fragment_history_detail_item_self" />
</RelativeLayout>

Use LinearLayout instead of RelativeLayout. And ser Orientation to vertical. So that the layout place top to bottom.

So, Your parent layout should be link this ->

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="?android:attr/colorBackground">

        <!--Your child layouts goes here-->


</LinearLayout>

试试下面的代码。这个对我有用。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">

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

<android.support.v7.widget.RecyclerView
    android:id="@+id/recyclerChat"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_weight="1" />
</LinearLayout>
