Android: Reading a large CSV file efficiently? -

-

i have large csv file (about 12000 lines) need parse , display in listview.

i don't want load entire file in memory, want read in 10 lines groups , when user clicks "load more" button, next 10 lines read , on.

any recommendations on how achieve in efficient way ?

thanks

well, here's starting point:

step #1: create arrayadapter, data model array of read-in rows

step #2: override getcount() return array size plus 1, accommodate "load more" row

step #3: override getviewtypecount() return 2 (or more, if listview rows csv rows not same -- assume same rest of answer, 2 types "regular row" , "'load more' row")

step #4: override getitemviewtype() return 1 when position equal array size, or 0 lower that

step #5: override getview() return appropriate row, including returning "load more" row

step #6: when user clicks "load more" row, run through logic read in next csv lines, adding them array, calling notifydatasetchanged() on adapter alert listview data has changed
