Answer 1

in your ImageView, add the following attribute:

app:layout_collapseMode="parallax"

Also, in your NestedScrollView tag, add the following:

app:layout_behavior="@string/appbar_scrolling_view_behavior"

Answer 2

Your ImageView should have attribute called

app:layout_collapseMode="parallax"

If you want to add Toolbar to your Layout there should be attribute called

app:layout_collapseMode="pin"

And finally You missed one attribute for NestedScrollView.

app:layout_behavior="@string/appbar_scrolling_view_behavior"
