public class historydetails { public historydetails(long date, string name, string url) { this.date = date; this.name = name; this.url = url; } public long date = 0; public string name = ""; public string url = ""; }
is there way can without listview current code?
use tablelayout , use getchildat set alternate row colors tablerow :
tablelayout tablelayout=(tablelayout) findviewbyid(r.id. tlgridtable); (int count = 0; count < tablelayout.getchildcount(); count++) { view view=tablelayout.getchildat(count); // access textviews row view viewtext1 = view.getchildat(0); view viewtext2 = view.getchildat(1); // access others in same way... if (count % 2 == 1) { view.setbackgroundcolor(color.blue); // set color textview's viewtext1.setbackgroundcolor(color.black); }else{ view.setbackgroundcolor(color.green); // set color textview's viewtext1.setbackgroundcolor(color.gray); } } and can access textview5, textview6, textview7 using view set different colors textview's in each row.
