Hi @rahuldevanavar91

Sorry for late response. Let me take a look

Hi @rahuldevanavar91

This example is quite closed to what you want to do. Please check. https://github.com/henrytao-me/smooth-app-bar-layout/blob/master/sample/src/main/res/layout/activity_smooth_view_pager_exit_util_collapsed.xml

Also note that: adding Toolbar outside CoordinatorLayout does not seem correct to me.
