On code behind;

SharedPreferences prefs = this.getSharedPreferences("title",Context.MODE_PRIVATE);
String LanSettining = prefs.getString("language", null);

You can also use following code:

Set:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
SharedPreferences.Editor editor = settings.edit(); 
                        editor.putString("language", language);
                        editor.commit();

Read:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(this);
String language = settings.getString("language", "");

  • the error said: The method getDefaultSharedPreferences(Context) in the type PreferenceManager is not applicable for the arguments (new DialogInterface.OnClickListener(){}) – user1710911 Nov 19 '13 at 10:39
  • You need to give the context of you activity and not of dialog. Just write there: ActivityName.this in place of context. – Sandeep Nov 19 '13 at 10:41
  • I have appreciate _Sandy_ your help but it always start MainActivity not the activity i have choose.. I have already store a Preference only i need read it from MainActivity. – user1710911 Nov 19 '13 at 10:57
  • Then you must be doing some small mistake. Try to print the value of shared preferences and see whether it's getting stored. – Sandeep Nov 19 '13 at 10:58
  • Yes, because when i opened setting.class an activity3 was chosen redirect to Activity3 – user1710911 Nov 19 '13 at 11:07
