How to maintain spinner state in android -


i'm doing android app can data web service & load spinner. need maintain selected data state of spinner while go screen & come back. example, if i'm getting data web service 1.apple 2.orange 3.grapes & loading spinner, select orange. when go other screen & come back, selected spinner data should orange. again loads data server spinner. can me resolve this?

my code:

@override public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);      //...      if (constants.spinner != null ) {         spinner.setselection( constants.spinner);     } else {         //webcall here getting data     }      //...      spinner.setonitemselectedlistener(new onitemselectedlistener() {         public void onitemselected(adapterview<?> parent,             view view, int arg2, long arg3) {                 constants.spinner = spinner.getselecteditemposition();

in constant class:

public static integer spinner="";

you can use 

  spinner.getselecteditemposition();

that return int can save 

  prefedit.putint();

then when want re-load has been saved call 

  spinner.setselection(prefs.getint("key", default));

or try this

to save:

  int selectedposition = yourspinner.getselecteditemposition()   editor.putint("spinnerselection", selectedposition);   editor.commit();

to load:

yourspinner.setselection(prefs.getint("spinnerselection",0));

if array used should changed this

 string selectedstring = yourarray[yourspinner.getselecteditemposition()];    editor.putstring("spinnerselection", selectedstring);    editor.commit();

checking array[i] against value stored in prefs.if use arraylist instead part done without loop calling

 arraylist.indexof(prefs.getstring("spinnerselection", "");

when commit show above array item gone. show no 1 array.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
