android - How to display a Toast using a Fragment within a Navigation Drawer -


i'm trying have toast displayed after select menu item navigation drawer , app switches fragment. have line of code inside oncreate() method fragment displayed when fragment inflated, except it's not working:

public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) {     myview = inflater.inflate(r.layout.post_layout, container, false);     //my toast wont work!!:(     toast.maketext(post_fragment.this, "it worked!", toast.length_short).show();     return myview; }

any thoughts? help.

try changing: 

toast.maketext(post_fragment.this, "it worked!", toast.length_short).show();

to

toast.maketext(getactivity(), "it worked!", toast.length_short).show();

or put maketext() call inside onnavigationitemselected() method in activity houses fragment. in case call similar this.

toast.maketext(this, "it workded!", toast.length_short).show();

the first parameter maketext() context object. docs context is:

interface global information application environment. abstract class implementation provided android system. allows access application-specific resources , classes, up-calls application-level operations such launching activities, broadcasting , receiving intents, etc.

your activity class extends context. fragment class not. method you're calling static, not have access application-specific resources , classes/etc. passing context (your activity), gives access resources.

cheers

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
