listview2 , listview6. have set adapters both listview properly. getting data backend. both listviews, getting 2 items backend showing 1 item in each listview. trying add item second listview, using notifydatasetchanged() not working too. getting 1 item. possible reason , how fix it?
here did, in case else having similar problem:
note: solution inefficient. using because have @ max 2 items in listview. not recommend others if have listview has significant number of items.
public static void setlistviewheightbasedonchildren(listview listview) { listadapter listadapter = listview.getadapter(); if (listadapter == null) { // pre-condition return; } int totalheight = listview.getpaddingtop() + listview.getpaddingbottom(); (int = 0; < listadapter.getcount(); i++) { view listitem = listadapter.getview(i, null, listview); if (listitem instanceof viewgroup) { listitem.setlayoutparams(new layoutparams(layoutparams.wrap_content, layoutparams.wrap_content)); } listitem.measure(0, 0); totalheight += listitem.getmeasuredheight(); } viewgroup.layoutparams params = listview.getlayoutparams(); params.height = totalheight + (listview.getdividerheight() * (listadapter.getcount() - 1)); listview.setlayoutparams(params); } i called function on both listviews after setting adapter. hope helps.
