java - 从屏幕顶部到底部的布局

Question

我有一个屏幕，其中有一个操作栏，然后是一本书的标题和章节本身。问题是，这一章从上到下，标题被切断了。章节文本还与顶部的应用栏和底部的底部导航 View 重叠。请帮忙

尝试将其作为 Activity_home 布局:

<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HomeActivity">

<LinearLayout
    android:id="@+id/liner_layout"
    android:orientation="vertical"
    android:layout_height="match_parent"
    android:layout_width="match_parent"
    >
    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="?attr/actionBarSize"
        android:background="@color/colorPrimary"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

    <include
        android:id="@+id/include"
        layout="@layout/content_home"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"/>

</LinearLayout>

<com.google.android.material.bottomnavigation.BottomNavigationView
    android:id="@+id/bottomNavigationView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    app:menu="@menu/nav_menu"
    android:layout_alignParentBottom="true" />

保留 content_home 布局不变。
