android - Store & Retrieve Button State using shared preference -


i making application has 2 button news , data.

if pressed news button display news in listview , same data.

the problem want store button state sharedpreference means, once selected news button, after exit when again run application want news button pressed , display news data listview.

how can implement ?

i using code not ..

    sharedpreferences preferences = preferencemanager.getdefaultsharedpreferences(this);      editor edit = preferences.edit();     edit.putstring("pref_empid", _empid);     edit.putstring("pref_usertype", _usertype);     edit.commit();

sorry bad english need thank in advance

at time of clicking news or data save preferencw value following:

sharedpreferences preferences = preferencemanager.getdefaultsharedpreferences(this);   editor edit = preferences.edit(); edit.putstring("which_list", "news"); // when clicking news button //  edit.putstring("which_list", "data"); // when clicking data button edit.commit();

when ever start activity, check shared preference value of which_list following:

string which_list = preferences.getstring("which_list", "");

now, compare:

if(which_list.equals("news")) {     //    load  news  list } else if(which_list.equals("data")) {     //    load  other  data  list }

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).
