Answer 1

Simply add your layout in Coordinatorlayout below NestedScrollView in xml and do the following in java.

CoordinatorLayout.LayoutParams layoutParams = (CoordinatorLayout.LayoutParams) layoutToBeAnchored.getLayoutParams();
    layoutParams.setAnchorId(R.id.layoutBelowWhichToBeAnchored);
    layoutParams.anchorGravity = Gravity.CENTER;
    layoutToBeAnchored.setLayoutParams(layoutParams);

Hope this helps you guys. For any reference you can check the example at - https://github.com/IsUncommon/Droidcon-India-2015

You can use Relativelayout as your outer layout and keep CoordinatorLayout inside it, make Two buttons android:layout_alignParentBottom="true"

 <?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <android.support.design.widget.CoordinatorLayout
        android:id="@+id/coordinate"
        android:layout_width="match_parent"
        android:layout_height="match_parent"

Answer 5

If your included layout layout="@layout/content_single_product" contains a NestedScrollView as a root view container. Try to add an id to it like @+id/nestedView with android:layout_height="match_parent", You must probably add bottom padding with the same height value of your buttons , and Just keep the rest as it is, and replace android:layout_gravity="bottom" inside your bottom linear layout which contains the two buttons with :

app:layout_anchor="@id/nestedView" app:layout_anchorGravity="bottom"
