android - Set Locale programmatically -

-

my app supports 3 (soon 4) languages. since several locales quite similar i'd give user option change locale in application, instance italian person might prefer spanish on english.

is there way user select among locales available application , change locale used? don't see problem set locale each activity since simple task perform in base class.

for people still looking answer, since configuration.locale deprecated can use api 24:

configuration.setlocale(locale);

take in consideration minskdversion method api 17.

full example code prior api 17:

resources resources = getresources(); configuration configuration = resources.getconfiguration(); displaymetrics displaymetrics = resources.getdisplaymetrics(); configuration.setlocale(locale); resources.updateconfiguration(configuration,displaymetrics);

edit

from api 25 updateconfiguration(configuration,displaymetrics) deprecated, should use createconfigurationcontext(configuration), documentation here

full example code api 17 or higher:

resources resources = getresources(); configuration configuration = resources.getconfiguration(); configuration.setlocale(locale); getapplicationcontext().createconfigurationcontext(configuration);

edit 2

full example code handle both cases:

@suppresswarnings("deprecation") private void setlocale(locale locale){     resources resources = getresources();     configuration configuration = resources.getconfiguration();     displaymetrics displaymetrics = resources.getdisplaymetrics();     if (build.version.sdk_int >= build.version_codes.jelly_bean_mr1){         configuration.setlocale(locale);         getapplicationcontext().createconfigurationcontext(configuration);     }     else{         configuration.locale=locale;         resources.updateconfiguration(configuration,displaymetrics);     } }

javascript - Enclosure Memory Copies -

-
function myclass() { //lots , lots of vars , code here. this.bar = function() { //do numerous enclosed myclass vars } this.foo = function() { alert('hello'); //don't enclosed variables. } } each instance of myclass gets own copy of bar , foo, why prototyped methods use less memory. however, know more memory use of inner methods. it seems obvious me (1) below must true. agree? not distinct myclass instances have own distinct copies of bar, must have own distinct copies of myclass enclosure. (or else how bar method keep myclass variables straight on per instance basis?) now (2) question i'm after. since inner foo method doesn't use in myclass enclosure natural qustion is: javascript smart enough not keep myclass enclosure in memory use of foo? this depend entirely on implementation not language. naive implementations keep far more around others. answer true e.g. v8 (chrome's js engine) may not true spider...

(in cases might this: {tag1({tag2({tag3()})})}) , on.) btw using preg_replace_callback, easier show preg_replace here site can test code: http://www.spaweditor.com/scripts/regex/index.php you need add curly braces character set. here's pattern used: /\{[a-za-z.,\(\)\{\}0-9]+\}/ and here result: "lorem ipsum dolor sit replaced, consectetur adipiscing elit."
