Limit data from CSV list

1st image is of my main blocks and 2nd one is for idea about indexing CSV list…

I m using CardView design which gets data from spreadsheet ( CSV formated data )

So, when my app gets more than some data limit, it causes issue while opening app.

So , maybe I think. I should use limit from index 1 to index 15 and when next button pressed , that index condition will change to next 16-30 index

the first thing you might want to learn is how to provide useful screenshots…

to limit the rows, which are returned from the database, use LIMIT, for example
SELECT images FROM <tableid> ORDER BY Number ASC LIMIT 15
