我有这个布局。此布局包含BottomNavigationView和嵌套片段的容器
<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout 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/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="client.MainActivity">
<include
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="match_parent" />
<android.support.design.widget.BottomNavigationView
android:id="@+id/navigation"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginEnd="0dp"
android:layout_marginStart="0dp"
android:background="?android:attr/windowBackground"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:menu="@menu/navigation" />
</android.support.constraint.ConstraintLayout>
如何在BottomNavigationView上方设置app_bar_main
?

我使用FrameLayout
来阻止BottomNavigationView
与其上方的布局重叠。
<?xml version="1.0" encoding="utf-8"?>

BottomNavigationDrawer是一个视图,因此您可以将其布局为:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent">
<include
android:layout_weight="1""
layout="@layout/app_bar_main"
android:layout_width="match_parent"
android:layout_height="0dp" />
<android.support.design.widget.BottomNavigationView
android:id="@+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?android:attr/windowBackground"
app:menu="@menu/navigation" />
</LinearLayout>
请注意,我替换为LinearLayout并填充了content_view以获取屏幕的剩余空间。
如果你想使用ConstraintLayout(不需要你的布局),解决方案将在content_view中有一个id并使其高于导航并在父级下方
