Why is my BottomBar in the middle of the screen?

Question

I'm using both NavigationDrawer and BottomNavigationView. But after the add Navigation Drawer, position of Bottom Navigation is changed. How do I solve that? I assume this problem is caused by my xml files.

activity_main.xml

<android.support.v4.widget.DrawerLayout  xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/activity_main"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start"
tools:context="com.example.yunus.ototakip.MainActivity">

<include
    layout="@layout/app_bar_navigation_bar"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

<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_navigation_bar"
    app:menu="@menu/activity_navigation_bar_drawer" />
<FrameLayout
    android:id="@+id/main_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_alignParentTop="true"
    android:layout_alignParentStart="true">
</FrameLayout>

<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/colorPrimary"
    app:itemIconTint="@color/beyaz"
    app:itemTextColor="@color/beyaz"
    app:menu="@menu/bottombar_menu" />

You know that `layout_alignParentBottom` is for `RelativeLayout`? — Selvin, Jan 18 '17 at 16:18

Attach your BottomNavigationView inside the CoordinatorLayout (or whatever view group you've inside app_bar_navigation_bar layout) not DrawerLayout and add appropriate gravity tag.

android:layout_gravity="bottom"

use android:layout_gravity="bottom" instead of layout_alignParentBottom as it is for RelativeLayout not android.support.v4.widget.DrawerLayout.

I get this error:BottomNavigationView at index 3 does not have a valid layout_gravity - must be Gravity.LEFT, Gravity.RIGHT or Gravity.NO_GRAVITY – Yunus Haznedar Jan 18 '17 at 16:27
