将表格行标题冻结到表格视图的垂直滚动

时间:2013-04-05 12:12:33

标签: java android android-layout scroll tableview

我有一个活动,其中我有一个表格布局。该表将通过活动动态填充。

由于表格水平很长,所以为了方便用户处理,我在 S.No。列之后实现了对表格的水平滚动。 S.No。列不应该直接暴露于水平滚动,而是可以实现。

整个表是可垂直滚动的,我想要的是将表的标题行冻结到垂直滚动,但是标题中的水平滚动以及S.No之后的所有行都应该存在。列。

这是活动代码

    public class ReportListActivity extends Activity {

    TableLayout srno_table;
    TableRow srno_report_tr_data;

    TableLayout report_table;
    TableRow report_tr_data;
