-

i'm using library in fragment, when run app swipemenulistview not showing contents, here on stack found guys using listview inside oncreateview method, tried didn't work

public class autorizadasfragment extends fragment {      private swipemenulistview listview;     private customarrayadapter adapter;     private list<string> data;      public autorizadasfragment() {     }      @override     public view oncreateview(layoutinflater inflater, viewgroup container,                              bundle savedinstancestate) {          view rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false);           return rootview;     }       @override     public void onactivitycreated(bundle savedinstancestate) {         // todo auto-generated method stub         super.onactivitycreated(savedinstancestate);          data = new arraylist<string>();          data.add("teste 1");         data.add("teste 2");         data.add("teste 3");         data.add("teste 4");         data.add("teste 5");          listview = (swipemenulistview) getactivity().findviewbyid(r.id.list);          adapter = new customarrayadapter(getactivity(), data);         listview.setadapter(adapter);         swipemenucreator creator = new swipemenucreator() {              @override             public void create(swipemenu menu) {                 // create "open" item                 swipemenuitem openitem = new swipemenuitem(                         getactivity());                 // set item background                 openitem.setbackground(new colordrawable(color.rgb(0xc9, 0xc9,                         0xce)));                 // set item width                 openitem.setwidth(90);                 // set item title                 openitem.settitle("open");                 // set item title fontsize                 openitem.settitlesize(18);                 // set item title font color                 openitem.settitlecolor(color.black);                 // add menu                 menu.addmenuitem(openitem);                  // create "delete" item                 swipemenuitem deleteitem = new swipemenuitem(                         getactivity());                 // set item background                 deleteitem.setbackground(new colordrawable(color.rgb(0xf9,                         0x3f, 0x25)));                 // set item width                 deleteitem.setwidth(90);                 // set icon                 deleteitem.seticon(r.drawable.ic_exit);                 // add menu                 menu.addmenuitem(deleteitem);             }         };          listview.setmenucreator(creator);     }       @override     public void oncreateoptionsmenu(menu menu, menuinflater inflater) {         // todo auto-generated method stub         super.oncreateoptionsmenu(menu, inflater);         inflater.inflate(r.menu.menu_main, menu);       } }

xml:

 <linearlayout         style="@style/formregister"         android:orientation="vertical"         android:weightsum="1"         android:layout_width="fill_parent"         android:layout_height="fill_parent">          <com.baoyz.swipemenulistview.swipemenulistview             android:id="@+id/list"             android:layout_width="fill_parent"             android:layout_height="match_parent"             android:scrollbars="vertical"/> </linearlayout>

you can hold reference root view adding private attribute e.g.

private view rootview = null;

and change following line in oncreateview:

view rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false);

to

rootview = inflater.inflate(r.layout.fragment_autorizadas, container, false);

then not need use "getactivity().findviewbyid(r.id.list);" (it become "rootview.findviewbyid(r.id.list);")

i proposing because not sure view created in oncreateview added activities root view when onactivitycreated() called.

java - UML - How would you draw a try catch in a sequence diagram? -

is there standard way of drawing try catch sequence diagrams? i've made attempt based on this feel end result doesn't feel right. code diagram based around: public static void save () { try { filehandle filehandle = gdx.files.external(file); filehandle.writestring(boolean.tostring(constantshandler.soundenabled)+"\n", false); (int = 0; < 5; i++) { filehandle.writestring(integer.tostring(constantshandler.highscores[i])+"\n", true); } } catch (throwable e) { } } my attempt note: know still need add loop. that's ok. fragments meant show conditional control flow in sequence diagram. superstructures puts limitations on use of fragments (see pp. 467 of ss2.1.1). should use critical region try part above. , option catch . however, keep telling can take quite freedom in using uml. it's language , such changes in life time. long reader ge...
