android:divider="#ffffff" >     </listview>  </linearlayout>

if 1 aware of such situation please me out.

use this

public class expandableheightlistview {     public static void setlistviewheightbasedonchildren(listview listview) {          listadapter listadapter = listview.getadapter();          if (listadapter == null) {             // pre-condition             return;         }          int totalheight = 0;          (int = 0; < listadapter.getcount(); i++) {              view listitem = listadapter.getview(i, null, listview);              listitem.measure(0, 0);              totalheight += listitem.getmeasuredheight();         }          viewgroup.layoutparams params = listview.getlayoutparams();          params.height = totalheight                 + (listview.getdividerheight() * (listadapter.getcount() - 1));          listview.setlayoutparams(params);      } }

in mainactivity pass listview object in method.

setlistviewheightbasedonchildren(listview);
