android - ListView in SYSTEM_ALERT_WINDOW -

i'am trying create system alert windows contain listview. have problems. can see there items in listview can not read text , nothing happens if click on items. let me add pictures of issue.

as see in first picture no items showing when showing layout bounds can see there 2 items in list.

    listview lw = new listview(this);     string[] stringarray = new string[] { "bright mode", "normal mode" };     arrayadapter<string> modeadapter = new arrayadapter<string>(this, android.r.layout.simple_list_item_1, android.r.id.text1, stringarray);     lw.setadapter(modeadapter);     layout.addview(lw); 

this how created list.

edit

i solved visibility issue have still issues clicking on items in list. strange thing works on samsung galaxy note not on other device. click logic.

        listview.setonitemclicklistener(new adapterview.onitemclicklistener() {         @override         public void onitemclick(adapterview<?> parent, view view, int position, long id) {             log.v("head", "click");         }     }); 

i suggest this:

string[] stringarray = new string[] { "bright mode", "normal mode" }; listview.setadapter(new arrayadapter<string>(this, android.r.layout.simple_list_item_1, stringarray ) {     @override     public view getview(int position, view convertview, viewgroup parent) {         textview textview = (textview) super.getview(position, convertview, parent);          string text = stringarray [position];         textview.settextcolor(color.black);         return textview;     } });
