Toolbar parent LinearLayout should be replaced with AppBarLayout to enable layout_scrollFlags for Toolbar programmatically

[LOG-TAG]

To enable hide action bar (or Tab bar) while scrolling the list we need to change the Toolbar's LinearLayout parent to AppBarLayout !!!

Error becouse of LinearLayout :

 AppBarLayout.LayoutParams params =
                (AppBarLayout.LayoutParams)   this.getToolbar().getLayoutParams();

        params.setScrollFlags(AppBarLayout.LayoutParams.SCROLL_FLAG_SCROLL
                | AppBarLayout.LayoutParams.SCROLL_FLAG_ENTER_ALWAYS);

this is the programmatic way but fails ending up error!!

java.lang.ClassCastException: android.widget.LinearLayout$LayoutParams cannot be cast to android.support.design.widget.AppBarLayout$LayoutParams

LinearLayout parent should be replaced to AppBarLayout!!
