I already tried references from similar question on SO, but hasn’t got the appropriate solution.
I’m trying to fetch the data from a webpage and display it in format consisting of rows having 4 columns.
Data present on webpage:
SBIN ;1916.00;1886.85;1.54@LT ;1315.50;1310.30;0.40@TCS ;1180.00;1178.00;0.17@AXISBANK ;1031.30;1005.95;2.52@MARUTI ;1000.35;992.35;0.81@PNB ;931.90;916.35;1.70@GAIL ;400.00;398.45;0.39@
I want to diaplay it in the form
SBIN.........1916.00.....1886.85.....1.54
LT...........1315.50.....1310.30.....0.40 and so on.
Note that I don’t want dots, I want each value to be a separate column within a row.
My Data consists of 7 rows.
When I run the below code, I get this output 
i.e.
values[0] values[1] values[2] values[3]
values[1] values[2] values[3] values[4]
values[2] values[3] values[4] values[5]
(It prints all 4 cols of 1st row, then col 2-4 of 1st row and col1 of 2nd row, then cols 3-4 of 1st row and col 1-2 of 2nd row and so on…)

ANY HELP APPRICIATED
Try using ListView
Instead of TableLayout add ListView to your xml and place the content on table in new xml
Create an adapter by extending ArrayAdapter and set this adapter on your listView.
