i'm trying write simple phonebook android app, , when try run it, gives me bunch of errors, , don't have idea mistakes. i'm trying right now, read in list of names file, , display in listview. code:

    public class mainactivity extends activity {      @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main);          final listview listview = (listview) findviewbyid(r.id.listview1);         final arraylist<string> names = new arraylist<string>();          try         {             scanner sc = new scanner(getassets().open(string.format("data.txt")));             while(sc.hasnextline())             {                 names.add(sc.nextline());             }          } catch (ioexception ioe) { system.out.println("failed load file"); }          final stablearrayadapter adapter = new stablearrayadapter(this,                 r.id.listview1, names);          listview.setadapter(adapter);     }      @override     public boolean oncreateoptionsmenu(menu menu) {         // inflate menu; adds items action bar if present.         getmenuinflater().inflate(r.menu.main, menu);         return true;     }      private class stablearrayadapter extends arrayadapter<string> {          hashmap<string, integer> midmap = new hashmap<string, integer>();          public stablearrayadapter(context context, int textviewresourceid,             list<string> objects) {             super(context, textviewresourceid, objects);             (int = 0; < objects.size(); ++i) {                 midmap.put(objects.get(i), i);             }         }          @override         public long getitemid(int position) {           string item = getitem(position);           return midmap.get(item);         }          @override         public boolean hasstableids() {           return true;         }     } }

and here logcat:

here's xml:

 final stablearrayadapter adapter = new stablearrayadapter(this,                 r.id.listview1, names);

the arrayadapter extending need second paramter id of textview want fill, not listview id. change in

 final stablearrayadapter adapter = new stablearrayadapter(this,                 android.r.layout.simple_list_item_1, names);

here:

   public stablearrayadapter(context context, int textviewresourceid,             list<string> objects) {             super(context, textviewresourceid, objects);             (int = 0; < objects.size(); ++i) {                 midmap.put(objects.get(i), i);             }      }

as can see providing super constructor id of listview. have provide id of textview

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
