java - Custom AlertDialog disappears on back button press -

-

hi guys have custom alert dialog created. in builder set cancelable false yet still disappears when press button, ideas?

this code dialog:

public final class hemispheredialogfragment extends dialogfragment { @override public dialog oncreatedialog(bundle savedinstancestate) {     // use builder class convenient dialog construction     alertdialog.builder builder = new alertdialog.builder(getactivity());     layoutinflater inflater = getactivity().getlayoutinflater();     view customtitle = inflater.inflate(r.layout.hemisphere_dialog_custom_title, null);     builder.setcustomtitle(customtitle);     string[] entries = new string[2];     entries[0] = getresources().getstring(r.string.northern_hemisphere);     entries[1] = getresources().getstring(r.string.southern_hemisphere);     builder.setitems(entries, new dialoginterface.onclicklistener() {         //the 'which' argument contains index position of selected item         public void onclick(dialoginterface dialog, int which) {             if( == 0 ) {                 globalvariables.getshared().setisinnorthernhemisphere(true);             } else if( == 1 ) {                 globalvariables.getshared().setisinnorthernhemisphere(false);             }              toolbaractivity.outfitsfragment.hemisphereselected();             globalvariables.getshared().sethasaskedforhemisphere(true);         }     });     builder.setcancelable(false);      //create alertdialog object , return     return builder.create(); }

and how it's displayed:

new hemispheredialogfragment().show(getsupportfragmentmanager(), "hemispheredialog");

another small side question, there way change text size items in dialog?

you set alert dialog cancelable false, fragment still set cancelable, need add setcancelable(false) fragment well.
