如何将底页扩展到工具栏底部，而不是在工具栏下方？

Question

我有bottomSheetLayout，当它进入扩展模式时进入工具栏布局，而我想到达工具栏？我将 layout_height 设置为 match_parent 是否需要在类中计算高度并将其设置为 deviceHeight-toolbarheight 并设置为 bottomSheet 布局高度？ 我在与小吃店一起使用时遇到问题

Answer 1

不要在 CoordinatorLayout 中添加工具栏。在 CoordinatorLayout 之外添加工具栏。制作基本的线性或真实布局。

例如：我使用 DrawerLayout 作为基本布局，如果您不希望可以删除它并简单地使用线性或真实布局。

<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout 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:id="@+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

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

    <include layout="@layout/dashboard" />
</LinearLayout>

<android.support.design.widget.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:fitsSystemWindows="true"
    app:headerLayout="@layout/nav_header_main2"
    app:menu="@menu/activity_main2_drawer" />

</android.support.v4.widget.DrawerLayout>

然后使用 CoordinatorLayout

<?xml version="1.0" encoding="utf-8"?<android.support.design.widget.CoordinatorLayout 
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/dashboard"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

   //here you can add your views

</LinearLayout>

<!-- Adding bottom sheet after main content -->
<include layout="@layout/bottom_sheet" />


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

现在底页将完全展开，直到工具栏不在工具栏下方或工具栏上方。

希望这会对你有所帮助。
