Dismiss non-cancelable dialog on fragment backPress - Android -


i have navigation drawer activity , many fragments reach via nav drawer.

in of these fragments, show dialog says "loading.." while background tasks happening.

now i've made dialogs not-cancellable dialog.setcancelable(false) user doesn't accidentally dismiss clicking anywhere on screen. makes un-cancelable when phone button pressed.

this code dialog - 

dialog dialog = new dialog(context);     dialog.requestwindowfeature(window.feature_no_title);     dialog.setcontentview(r.layout.custom_progress_dialog);     ((textview)dialog.findviewbyid(r.id.custom_dialog_message)).settext("loading ...");      dialog.setcancelable(false);          dialog.show();

i need write code dismiss loading dialog , go previous fragment when phone button pressed while on fragment.

can me out? need implementing backpress specific fragment. thanks!

you can use getfragmentmanager().popbackstackimmediate();

dialog.setonkeylistener(new dialog.onkeylistener() {         @override         public boolean onkey(dialoginterface dialog, int keycode, keyevent event) {             // todo auto-generated method stub             if (keycode == keyevent.keycode_back) {                 dialog.dismiss();                 getfragmentmanager().popbackstackimmediate();             }             return true;         }     });

javascript - Why does running this loop 9 times take 100x longer than running it 8 times? -

consider code: test = function() { } t = new test(); (var = 0; < 8; i++) { result = t instanceof test; } if change number of iterations 8 9 , loop take 100 times longer complete in latest version of firefox (41.0.1). tested on 2 different pcs , magic limit 8. here jsperf test used: http://jsperf.com/instanceof-8-times-vs-9-times does have idea why might happen? seems specific instanceof . not happen if else object, example check property. note: filed bugzilla bug this. jan de mooij mozilla team has posted details in bugzilla thread . here's simplistic interpretation of highly technical answers: in i < 8 case, firefox smart enough hoist result = t instanceof test; statement out of loop (according tests, doesn't seem omit altogether). in i < 9 case, apparently doesn't optimization . why? reason not clear, related fact 9 iterations threshold above function considered "hot" enough run through jit compiler. i < 8 cas...
