LinearLayoutManager layoutManager = new LinearLayoutManager(this, LinearLayoutManager​.​HORIZONTAL​, false);
RecyclerView myList = (RecyclerView) findViewById​(​R​.​id​.​my_recycler_view​);
myList​.​setLayoutManager​(​layoutManager​);

So according to your question you have to add weight to the child elements which you can be given from parent layout like ex: recyclerview weight 3, and its item weight 1 each(if you have 3 items and fit in the width with margins on either sides) and consider to assign 3 to 6 elements in the width of the screen with horizontal scrolling
mRecyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.HORIZONTAL, true));

Empty spaces at the end of row Recyclerview with GridLayoutManger

I am using recyclerview with gridlayoutmanger with spancount 2 containing fixed 12 elements only in recyclerview.On tablets in landscape mode the empty space is remaining after the sixth element. I want to fill the empty space with the elements from second row. If space is there than then first row contain either 6, 7, 8 ,9 ... elements depends upon the remaining space.

Use FlexLayoutManger with recycler view :
RecyclerView recyclerView = (RecyclerView) context.findViewById(R.id.recyclerview);
FlexboxLayoutManager layoutManager = new FlexboxLayoutManager(context);
layoutManager.setFlexDirection(FlexDirection.COLUMN);
layoutManager.setJustifyContent(JustifyContent.FLEX_END);
recyclerView.setLayoutManager(layoutManager);

set max rows 4 and columns to be dynamic in RecyclerView GridLayoutManager

I want a grid view which adds elements in new row each time when the row count reach 4 it should start adding element in 1st row.
Let say I have 7 items in 1st image and add 2 more elements then it should add first element at last index of 2nd column and second element at 1 index of column 3
Let say I have 11 items in 2nd image and add 2 more elements then it should add first element at last index of 3rd column and second element at 1 index of column 4

Try this:
GridLayoutManager layoutManager =
new GridLayoutManager(getActivity(), 4);
layoutManager.setOrientation(RecyclerView.HORIZONTAL);
recyclerView.setLayoutManager(layoutManager);

try this
GridLayoutManager gridLayoutManager = new GridLayoutManager(this, 4, GridLayoutManager.HORIZONTAL, false);
recycleView.setLayoutManager(gridLayoutManager);
