android - How to refresh activity after changing language? -


i search on google & stackoverflow can't solve problem. refer http://www.androhub.com/android-building-multi-language-supported-app/ have 3 activities (activity 1,2,3). activity 1 > activity 2 > activity 3 (milti lang change). in activity 3, have 2 radio button change (en, hi). after change language; go first activity (activity 1), ok. want stay current activity (refresh current activity), after choose radio button (changed language). otherwise, how recall oncreate() when go onbackpressed(). how best way stay current activity after change language.

oncreate

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main3);      txt = (mmtextview) findviewbyid(r.id.txt);     radiogroup = (radiogroup) findviewbyid(r.id.radiogroup);      pref = getsharedpreferences("mypref", activity.mode_private);     editor = pref.edit();      radiogroup.setoncheckedchangelistener(new radiogroup.oncheckedchangelistener() {         @override         public void oncheckedchanged(radiogroup radiogroup, @idres int i) {             string lang = "en";             switch (i) {                 case r.id.eng:                     lang = "en";                     intent i1 = new intent(main3activity.this, mainactivity.class);                     i1.addflags(intent.flag_activity_clear_top | intent.flag_activity_new_task);                     startactivity(i1);                     finish();                     break;                 case r.id.hi:                     lang = "hi";                     intent i2 = new intent(main3activity.this, mainactivity.class);                     i2.addflags(intent.flag_activity_clear_top | intent.flag_activity_new_task);                     startactivity(i2);                     finish();                     break;                 default:                     break;             }             changelocale(lang);         }     });      loadlocale(); }

changelocale

private void changelocale(string lang) {     if (lang.equalsignorecase(""))         return;     locale mylocale = new locale(lang);      savelocale(lang);       locale.setdefault(mylocale);         configuration config = new configuration();      config.locale = mylocale;        getbasecontext().getresources().updateconfiguration(config, getbasecontext().getresources().getdisplaymetrics());   }

savelocale & loadlocale

private void savelocale(string lang) {     editor.putstring("save", lang);     editor.commit(); }  private void loadlocale() {     string lang = pref.getstring("save", "");     changelocale(lang); }

you can close , open same activity like:

startactivity(new intent(activityname.this, activityname.class)); finish();

i hope works.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
