android - Show DialogFragment from another DialogFragment -


hello have dialogfragment displays list of options user , 1 of these options "delete" option ,when user press delete option want show dialogfragment confirmation , unfortunately confirmation dialog doesnot show .

here code

first fragment code

public class contactdialogoption extends sherlockdialogfragment {      public static final string tag = contactdialogoption.class.getsimplename();      public contactdialogoption() {         super();         // todo auto-generated constructor stub     }      @override     public dialog oncreatedialog(bundle savedinstancestate) {         alertdialog.builder builder = new alertdialog.builder(getactivity());          builder.seticon(r.drawable.ic_launcher);         builder.settitle(r.string.options);          builder.setitems(new string[] {          getstring(r.string.call), getstring(r.string.send_message),                 getstring(r.string.copy), getstring(r.string.edit),                 getstring(r.string.delete)          }, new dialoginterface.onclicklistener() {              @override             public void onclick(dialoginterface dialog, int which) {                           if(which == 4) //delete                           { fragmentmanager mgr = getactivity().getsupportfragmentmanager();     fragmenttransaction ft = mgr.begintransaction();         fragment old = mgr.findfragmentbytag("secondfragment");         if (old != null) {             ft.remove(old);         }         ft.addtobackstack(null);   fragment.show(ft, fragmenttag);                           }             }         });          return builder.create();     } }

i got exact same problem, situation not happen when try open dialogfragment fragment.

the solution found modify following call:

fragment.show(ft, fragmenttag);

to:

fragment.show(getfragmentmanager(), fragmenttag);

the problem solution cannot work on fragmenttransition.

i don't understand why behavior different fragments.

css - Text drops down with smaller window -

i've adapted css use in website , can't quite figure out why 1 aspect of page acting way acting. basically, when shrink window below size horizontally, of text "drops down". becomes issue if user viewing website through ipad vertical orientation. can view issue here . i'm hoping make if window gets smaller, placement of text remains intact. the problem area not have enough space put both side navigation , content on 1 line. make automatically adjust page's width when exceeds decrements of width. this code example, , highly unlikely work. if see css more clearly, provide exact code. @media , (max-width:960px) { /* assuming #wrapper 960px across */ #content {width:560px;} /* opposed 720px */ } edit the content drops down @ 980px, have shrink width after there. @media , (max-width:980px) { #container {width:520px;} }
