this is my other View(which contains button) which i have to add at the bottom of RecyclerView not inside.(Only on particular screen not on multiple screen display)

****what can be done so that i can set the view (Containing buttons) at the bottom of the screen? (i am not able to add the view.) ****

Answer 1

Please share some of your code that can be useful to answer as well (as the layout xml).

What you could do is to put into your View a Layout with a given id. Then in your activity set the visibility of the layout you want to hide as "GONE", as:

findViewById<LinearLayout>(R.id.page_layout_3).visibility = View.GONE // this goes into the activity 

See the following example where the LinearLayout with id "page_layout_3" is hide as I wrote. The following layout will generate a page having a Scrollable List and with the navbar at the bottom.

You can replace the ListView with your ReciclerView.

UPDATE ANSWER:

Once you have your "recyvleviewlayout.xml" or whatever, you can include it using the Include tag provided by android (https://developer.android.com/training/improving-layouts/reusing-layouts), so you can use or not pending on the activity (screen?) you are in. Make sure you have a layout base where to include it by having a layout for every activity.
