底部导航上方的底部工作表 [英] Bottom Sheet Above Bottom Navigation

问题描述

我的目标是在 BottomNavigationView 上方放置一个底页，如下所示：

My goal is to place a "bottom sheet" on top of a BottomNavigationView like this:

< a href = https://i.stack.imgur.com/FVQ7D.jpg rel = nofollow noreferrer>

但是它保持以下方式。两种视图都折叠：

But it stays the following way. Both views collapse:

这是xml我的主要活动：

This is the xml of my main activity:

<?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"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/tierrota"
tools:context="com.example.juanjose.myapplication.ViajesActivity">

<!-- include main content -->
<include layout="@layout/bottomsheet" />

<!-- include bottom sheet -->
<include layout="@layout/bottom_navigation" />

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

bottom_navigation的代码：

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

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    app:itemBackground="@color/colorClarito"
    app:itemIconTint="@drawable/nav_item_color_state"
    app:itemTextColor="@drawable/nav_item_color_state"
    app:menu="@menu/bottom_navigation_main" />

</RelativeLayout>

底层代码

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
app:behavior_hideable="false"
app:behavior_peekHeight="80dp"
app:layout_behavior="android.support.design.widget.BottomSheetBehavior">

<TextView
    android:layout_width="match_parent"
    android:layout_height="80dp"
    android:background="@color/colorBackgroundSemi"
    android:gravity="center"
    android:text="Bandeja de entrada"
    android:fontFamily="@font/eraslght"
    android:textColor="@color/colorLetra"
    app:layout_anchor="@+id/bottom_navigation"
    app:layout_anchorGravity="top"/>

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:text="coisa2"
    android:textColor="@android:color/white" />

</LinearLayout>

我对这两个要素不熟悉。

I am new with these two elements. Is there someone who knows any way to achieve what I'm looking for?

我希望我的基本工作表照此行事并可以扩展。我的最终目标是在 BottomSheet 内添加 RecyclerView 。

I want my "bottom sheet" to act as such and can expand. My ultimate goal is to add a RecyclerView inside the BottomSheet.

推荐答案

将两个元素包装在线性布局中。不确定协调器布局的行为方式，但我认为它不允许您对元素进行排序（类似于框架布局）。

Wrap the two elements inside a linear layout. Not sure how coordinator layout behaves but I think it will not allow you to "order" elements (similar to frame layout).
