android - Scroll View not Scrolling -

i'm adding image view linear layout, linear layout added scroll view. i'm displaying scroll view window manager, because happening service. can see scroll bar, , when drag , down scroll bar moves image views don't.

here's code:

// define 2 views     scroll = new scrollview(this);     trayapplist = new linearlayout(this);  //define basic layout properties trayapplist.setorientation(linearlayout.vertical);         width = 50;         height = display.getheight();          // shortcut list container         lstparams = new windowmanager.layoutparams(windowmanager.layoutparams.wrap_content, windowmanager.layoutparams.fill_parent, windowmanager.layoutparams.type_system_alert, windowmanager.layoutparams.flag_not_focusable | windowmanager.layoutparams.flag_layout_in_screen, pixelformat.translucent);         lstparams.gravity = docklocation;         scroll.setlayoutparams(new android.view.viewgroup.layoutparams(windowmanager.layoutparams.wrap_content, height));  //define window manager windowmanager wm = (windowmanager) getsystemservice(window_service);  //now display views      scroll.setscrollcontainer(true); scroll.addview(trayapplist); wm.addview(scroll, lstparams); 

you can try below:

scrollview scroll = new scrollview(context); scroll.setbackgroundcolor(android.r.color.transparent); scroll.setlayoutparams(new layoutparams(layoutparams.fill_parent,layoutparams.fill_parent)); scroll.addview(yourtableview);
