Android: Communication between Fragment and another Fragment directly on top of it -


as understand, if want communicate between 2 fragments, on underlying activity. however, 2 fragments not on same hierarchy level, because 1 fragment gets opened within/on top of fragment.

if click button on overlaying fragment, there way communicate directly holding fragment, without going detour on activity? because messy.

a button click on fragment 1 opens fragment 2 in framelayout in fragment 1. sounds big detour send fragment 2 interaction underlying activity , fragment 1.

if understand correctly, mlistener activity, not fragment holds 2nd fragment

 @override public void onattach(context context) {     super.onattach(context);     if (context instanceof onfragmentinteractionlistener) {         mlistener = (onfragmentinteractionlistener) context;     } else {         throw new runtimeexception(context.tostring()                 + " must implement onfragmentinteractionlistener");     } }

personally, i'd send through activity. but, use message bus instead.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
