I have an activity in which I am having a table layout. The table is getting dynamically populated through the activity.
As the table is horizontally very long, so to ease user handling, I have implemented horizontal scrolling to the table after the S.No. column. The S.No. column should not be exposed to horizontal scrolling ever and that is achieved.
The whole table is vertically scrollable, what I want is to freeze the header row of the table to vertical scrolling, but horizontal scrolling should be present in the header as well as all the rows after S.No. column.
This is the 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);
