        android:id="@+id/coordinatorLayout"
        android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"

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

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

    <fragment

        app:layout="@layout/fragment_navigation_drawer"
        tools:layout="@layout/fragment_navigation_drawer" />


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

This is actual FAB layout.

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="wrap_content">

<android.support.design.widget.FloatingActionButton
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="end|bottom"
    android:clickable="true"
    android:src="@drawable/cart"
    android:layout_margin="20dp"
    app:elevation="6dp" />

</FrameLayout>

This FAB is displaying in top right in layout. I want to display it on bottom right.

Can anyone help me on this?

Answer 1

Include your FAB layout in your parent layout giving layout_alignParentBottom property true:

    <include layout="@layout/activity_dialog"
     android:layout_alignParentBottom="true"
     android:layout_alignParentRight="true"
     android:layout_height="wrap_content"
     android:layout_width="wrap_content"/>  

Also try to change CoordinatorLayout android:layout_height="fill_parent" :

    <android.support.design.widget.CoordinatorLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_alignParentTop="true"
    android:id="@+id/coordinatorLayout"
    android:orientation="vertical">

Answer 2

Remove the <include> tag.

Place your FAB in its place with the <anchor> tag:

app:layout_anchorGravity="bottom|right|end"

<android.support.design.widget.FloatingActionButton
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/fab"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:layout_anchorGravity="bottom|right|end"
    android:clickable="true"
    android:src="@drawable/cart"
    android:layout_margin="20dp"
    app:elevation="6dp" />

If you still aren't winning, revise your layout by referring to this: FAB in the corner.
