baseadapter listview :-
public class listview_adapter extends baseadapter { context context; string[] list; layoutinflater inflater; public listview_adapter(context context , string[] list ) { this.context = context; this.list = list; inflater =(layoutinflater) context.getsystemservice(context.layout_inflater_service); } @override public int getcount() { // todo auto-generated method stub return list.length; } @override public object getitem(int position) { // todo auto-generated method stub return null; } @override public long getitemid(int position) { // todo auto-generated method stub return 0; } @override public view getview(int position, view convertview, viewgroup parent) { view view = convertview; view= inflater.inflate(r.layout.cust_row_listview, null); textview drawer_item = (textview) view.findviewbyid(r.id.drawer_item); string item = list[position]; drawer_item.settext(item); typeface type = typeface.createfromasset(context.getassets(), "robot_condensed_light.ttf"); drawer_item.settypeface(type); /* if(position==0){ view.setbackgroundcolor(color.parsecolor(context.getresources().getstring(r.string.color_list_1))); } else if(position == 1){ view.setbackgroundcolor(color.parsecolor(context.getresources().getstring(r.string.color_list_2))); } else if(position == 2){ view.setbackgroundcolor(color.parsecolor(context.getresources().getstring(r.string.color_list_3))); } else if(position == 3){ view.setbackgroundcolor(color.parsecolor(context.getresources().getstring(r.string.color_list_4))); } else if(position == 4){ view.setbackgroundcolor(color.parsecolor(context.getresources().getstring(r.string.color_list_5))); }*/ return view; } } this implementation of how navigate through fragments
lv = (listview) findviewbyid(r.id.drawerlist_1); listview_adapter adapter1 = new listview_adapter(this, item1); lv.setadapter(adapter1); fragment_home frag = new fragment_home(); fragmanager = getsupportfragmentmanager(); fragmanager.begintransaction().replace(r.id.framelayout, frag).commit(); lv.setonitemclicklistener(new onitemclicklistener() { @override public void onitemclick(adapterview<?> parent, view view, int position, long id) { //lv.setitemchecked(position, true); //v.setselection(position); lv.setselected(true); fragment frag; if (position == 0) { // getsupportactionbar().setbackgrounddrawable(new // colordrawable(getresources().getcolor(r.string.color_list_2))); getsupportactionbar().settitle("home"); frag = new fragment_home(); fragmanager.begintransaction() .replace(r.id.framelayout, frag).commit(); } else if (position == 1) { // getsupportactionbar().setbackgrounddrawable(new // colordrawable(color.parsecolor(getresources().getstring(r.string.color_list_2)))); frag = new fragment_paytmwallet(); fragmanager.begintransaction() .replace(r.id.framelayout, frag).commit(); getsupportactionbar().settitle("paytm wallet"); // if(build.version.sdk_int>=21){ // window window = getwindow(); // window.addflags(windowmanager.layoutparams.flag_draws_system_bar_backgrounds); // window.clearflags(windowmanager.layoutparams.flag_translucent_status); // window.setstatusbarcolor(color.parsecolor(getresources().getstring(r.string.color_list_primary_2))); // } } else if (position == 2) { // getsupportactionbar().setbackgrounddrawable(new // colordrawable(color.parsecolor(getresources().getstring(r.string.color_list_3)))); frag = new fragment_categories(); fragmanager.begintransaction() .replace(r.id.framelayout, frag).commit(); getsupportactionbar().settitle("categories"); // if(build.version.sdk_int>=21){ // window window = getwindow(); // window.addflags(windowmanager.layoutparams.flag_draws_system_bar_backgrounds); // window.setstatusbarcolor(color.parsecolor(getresources().getstring(r.string.color_list_primary_3))); // } } else if (position == 3) { // getsupportactionbar().setbackgrounddrawable(new // colordrawable(color.parsecolor(getresources().getstring(r.string.color_list_4)))); frag = new fragment_askaques(); fragmanager.begintransaction() .replace(r.id.framelayout, frag).commit(); getsupportactionbar().settitle("ask question"); // if(build.version.sdk_int>=21){ // window window = getwindow(); // window.addflags(windowmanager.layoutparams.flag_draws_system_bar_backgrounds); // window.setstatusbarcolor(color.parsecolor(getresources().getstring(r.string.color_list_primary_4))); // } } else if (position == 4) { // getsupportactionbar().setbackgrounddrawable(new // colordrawable(color.parsecolor(getresources().getstring(r.string.color_list_5)))); frag = new fragment_beanexpert(); fragmanager.begintransaction() .replace(r.id.framelayout, frag).commit(); getsupportactionbar().settitle("be expert"); // if(build.version.sdk_int>=21){ // window window = getwindow(); // window.addflags(windowmanager.layoutparams.flag_draws_system_bar_backgrounds); // window.setstatusbarcolor(color.parsecolor(getresources().getstring(r.string.color_list_primary_5))); // } } dl.closedrawers(); } });
follow steps below.
in adapter create variable below , getter function.
int mselecteditem; public void setselecteditem(int selecteditem) { this.mselecteditem = selecteditem; notifydatasetchanged(); } under getview method include below.
if (position == mselecteditem) { drawer_item.settextcolor.setbackgroundcolor(contextcompat.getcolor(context, r.color.selected_color)); // highlighting color } else { drawer_item.settextcolor(contextcompat.getcolor(context, android.r.color.normal_color)); // normal color } in mainactivity call setselecteditem passing position below under onitemclick.
adapter.setselecteditem(position); by have changed highlighted text color. can follow same set background. check if works you.
