Recyclerview covered by BottomNavigationView in CoordinatorLayout

Set the recycle veiw or whatever view its in, height to 0dp and weight 1. This will make it take all the available space left.

You can put the RecyclerView and the BottomNavigationView in a LinearLayout, and then put the LinearLayout in the CoordinatorLayout. Set the attribute of RecyclerView as layout_height="0dp" layout_weight="1", and the attribute of the BottomnavigationView as layout_height="wrap_content" layout_gravity="bottom".

Here is part of my code, wish to help you.

<android.support.design.widget.CoordinatorLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.design.widget.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.v7.widget.Toolbar
            android:id="@+id/manager_main_toolbar"
            android:layout_width="match_parent"
            android:layout_height="?attr/actionBarSize"
            android:background="?attr/colorPrimary"
            android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light" />

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

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">

        <android.support.v4.widget.SwipeRefreshLayout
            android:id="@+id/swipe_refresh"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_weight="1">

            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycler_view"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />

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

        <android.support.design.widget.BottomNavigationView
            android:id="@+id/bottom_nav"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_gravity="bottom"
            android:background="?android:attr/windowBackground" />

    </LinearLayout>

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

Here my solution, is working for me.

I have almost the same layout as you, I moved the BottomNavigationView out of the CoordinatorLayout as I don't need any animation on it. I've aligned BottomNavigationView to the parent's bottom, and added layout_above to CoordinatorLayout to have it above the BottomNavigationView but filling all the screen.

With this configuration I fixed the overlapping issue, I hope this would help you.

Here you have my layout.

    <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=".ui.activities.MainActivity">

        <android.support.design.widget.CoordinatorLayout
                android:id="@+id/main_coordinator"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:fitsSystemWindows="true"
                android:layout_above="@+id/dashboard_navigation">

            <android.support.design.widget.AppBarLayout
                    android:id="@+id/main_appbar"
                    android:layout_width="match_parent"
                    android:layout_height="?attr/actionBarSize"
                    android:elevation="16dp">

                    <android.support.v7.widget.Toolbar
                        android:id="@+id/dashboard_toolbar"
                        android:layout_width="match_parent"
                        android:layout_height="?attr/actionBarSize"
                        android:background="@color/colorPrimary"/>
            </android.support.design.widget.AppBarLayout>

            <FrameLayout
                    android:id="@+id/main_frame_layout"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"/>

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

        <android.support.design.widget.BottomNavigationView
                android:id="@+id/dashboard_navigation"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_alignParentBottom="true"
                android:background="@color/colorPrimaryDark"
                app:itemTextColor="@color/colorAccent"
                app:menu="@menu/menu_main"/>
    </RelativeLayout>

One of the most useful feature of CoordinatorLayout is view dodging.

Child views of the CoordinatorLayout can be assigned as "insetting" an edge. Any other child view that you assign as dodging that same edge will then be adjusted to suit.

In your case you would do something like the following:

<android.support.design.widget.AppBarLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:theme="@style/AppTheme.AppBarOverlay">

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

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

<include 
    layout="@layout/content_main"
    app:layout_dodgeInsetEdges="bottom" />   <-- Specifies this view dodges any views that inset the bottom edge

<android.support.design.widget.BottomNavigationView
    android:background="#fcfcfc"
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|end"
    app:menu="@menu/bottom_navigation"
    app:layout_insetEdge="bottom" />      <-- Specifies that this view insets the bottom edge

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