Show dynamic list of numbers in horizontal scrolled recyclerview with max 5 rows. Numbers size depend on current weeks number. If current weeks number is 45, then there will be 45 items. I can show them as below (vertically increasing) with GridLayoutManager.

1 6 11 16 
2 7 12 17
3 8 13 18
4 9 14 19
5 10 15 20

<----------->

But I want them to be shown as below (horizontal increasing)

1 2 3 4 5

6 7 8 9 10

11 12 13 14 15

16 17 18 19 20

21 22 23 24 24

<--------------->

Here just for simplicity I started numbers from 1. In real application numbers can start from 100 or 1000.

Edit

Now what I've.

As you can see numbers are decreased vertically. I want them to be decreased horizontally.

Below is my adapter

class SINumberAdapter(val context: Context, val list:List<String>): RecyclerView.Adapter<SINumberAdapter.NumberViewHolder>()
 override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): NumberViewHolder 

 val textView = TextView(parent.context)
 textView.layoutParams = LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT,LinearLayout.LayoutParams.WRAP_CONTENT)
 val paddingInPixels = 5.toPx
 textView.setPadding(paddingInPixels, paddingInPixels, paddingInPixels, paddingInPixels)
 return NumberViewHolder(textView)
 

 override fun getItemCount() = list.size

 override fun onBindViewHolder(holder: NumberViewHolder, position: Int) 
 holder.view.text = list[position]
 

 inner class NumberViewHolder(val view:TextView):RecyclerView.ViewHolder(view)
 init 
 view.setOnClickListener 
 
 

Edited answer

Assuming that max column size is fixed or will be known before setting the adapter.

following global declarations

int maxColumn = 8;
int spanCount = 1;
String list = "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13",
 "14", "15", "16", "17", "18", "19", "20";

inside onCreate

spanCount = list.length / maxColumn + 1;

mGridLayoutManager = new GridLayoutManager(mContext, spanCount, GridLayoutManager.HORIZONTAL, false);

above I calculated the required span size for a given length of array and number of column

sample adapter code

private class MyAdapter extends RecyclerView.Adapter<MyHolder> 

 int firstRowPos = 0;

 @NonNull
 @Override
 public MyHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) 
 return new MyHolder(LayoutInflater.from(parent.getContext())
 .inflate(R.layout.row_item, null));
 

 @Override
 public void onBindViewHolder(@NonNull MyHolder holder, int position) 

 if (position % spanCount == 0) 
 firstRowPos = position;
 holder.txtView.setText(list[position / spanCount]);
 else 
 if (((position - firstRowPos) * maxColumn + position / spanCount) < list.length)
 holder.txtView.setText(list[(position - firstRowPos) * maxColumn + position / spanCount]);
 else
 holder.txtView.setText("");
 
 

 @Override
 public int getItemCount() 
 return spanCount * maxColumn;
 

in adapter total count is returned as product of number of columns and number of rows (calculated span size)

now assume a grid of size column x row
write down the position of the elements in each cell as you want (going horizontally in your case), for example below

0 1 2 3 4
5 6 7 8

but the arrangement in recycler view will be as

0 2 4 6 8
1 3 5 7

from here you just need to figure out the formula which will be a function of position, row number, column number

that formula for 0th row is - all those positions which are integral multiple of total row count (span size)

for all other rows, it's

(position - (position from first row & that column)) x number of columns + calculated position from first row & that column which was used to fill the first row

sample (based on above example)
at 5th position in adapter, 7th position from data array has to sit, so
(5 - 4) x 5(column count) + 2 (from required first row) = 7

Care has to be taken though for the places where the above formula gives values more than array length
