        app:buttonIcon="@drawable/ic_add"
        app:layout_anchorGravity="top|center" />


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

the behaviour that i expected is, i can scroll either i touch in "txtPhone" or "txtAddress" or "txtView5" and also in "reviewList"

any idea?

Try to wrap the LinearLayout inside a NestedScrollView layout.

<android.support.v4.widget.NestedScrollView 
    android:id="@+id/nestedScrollView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
  <LinearLayout
        android:id="@+id/linearLayout"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        app:layout_behavior="@string/appbar_scrolling_view_behavior">
..
..
..
</LinearLayout>
</android.support.v4.widget.NestedScrollView>
