java - Freeze table row header to vertical scroll of table view -
i have activity in having table layout. table getting dynamically populated through activity.
as table horizontally long, ease user handling, have implemented horizontal scrolling table after s.no. column. s.no. column should not exposed horizontal scrolling ever , achieved.
the whole table vertically scrollable, what want freeze header row of table vertical scrolling, horizontal scrolling should present in header rows after s.no. column.
this activity code:
public class reportlistactivity extends activity { tablelayout srno_table; tablerow srno_report_tr_data; tablelayout report_table; tablerow report_tr_data; @override protected void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); setcontentview(r.layout.activity_report_list); srno_table=(tablelayout) findviewbyid(r.id.srno_table); //---------------serial no table header----------------------------------------------- tablerow srno_tr_head = new tablerow(this); srno_tr_head.setid(10); srno_tr_head.setbackgroundcolor(color.gray); srno_tr_head.setlayoutparams(new layoutparams( layoutparams.fill_parent, layoutparams.wrap_content)); textview label_sr_no = new textview(this); label_sr_no.setid(20); label_sr_no.settext("s.no."); label_sr_no.settextcolor(color.white); label_sr_no.setpadding(5,5,5,5); srno_tr_head.addview(label_sr_no);// add column table row here label_sr_no.settextsize(20);
