Hi, I have tried getActivity (), now the code is error free but i have no listview displayed in the tabs.
ArrayList<NameImg[]> list_NameImg = new ArrayList<NameImg[]>(); list_NameImg.add(basic); list_NameImg.add(sensors); list_NameImg.add(fastobjects); list_NameImg.add(pantilt); list_NameImg.add(usb); ModesLvAdapter adapter = new ModesLvAdapter(getActivity (), R.layout.my_list_item, list_NameImg.get(tab_idx)); myLV = (ListView) myLV.findViewById(R.id.customListView); View v = inflater.inflate(R.layout.modes_lv, null); myLV.setAdapter(adapter); On Thursday, July 23, 2015 at 8:07:38 PM UTC+2, MagouyaWare wrote: > > A fragment is not a Context.
