布局从屏幕的顶部到底部

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，章节从上到下，标题被截断。章节文本还与顶部的应用栏和底部的底部导航视图重叠。请帮忙

试试这个作为 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&nbsp; &nbsp; android:id="@+id/liner_layout"&nbsp; &nbsp; android:orientation="vertical"&nbsp; &nbsp; android:layout_height="match_parent"&nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; >&nbsp; &nbsp; <androidx.appcompat.widget.Toolbar&nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/toolbar"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="?attr/actionBarSize"&nbsp; &nbsp; &nbsp; &nbsp; android:background="@color/colorPrimary"&nbsp; &nbsp; &nbsp; &nbsp; app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />&nbsp; &nbsp; <include&nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/include"&nbsp; &nbsp; &nbsp; &nbsp; layout="@layout/content_home"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; app:layout_behavior="@string/appbar_scrolling_view_behavior"/></LinearLayout><com.google.android.material.bottomnavigation.BottomNavigationView&nbsp; &nbsp; android:id="@+id/bottomNavigationView"&nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; app:menu="@menu/nav_menu"&nbsp; &nbsp; android:layout_alignParentBottom="true" />保持 content_home 布局不变。
