Storing Integers In Preference Class

In my android app I have created a preference class(which extends PreferenceActivity) for storing about 10 integer values. I am not creating any xml file for that activity in R.xml

Solution 1:

Hi here i added sample code for SharedPreferences for you concern .please try this code and let me know. Hope it should helpful for you. Thanks.

SharedPreferences Creation:

SharedPreferencessharedPref= getBaseContext().getSharedPreferences("USER_PREFS",Context.MODE_PRIVATE);

Store the values to SharedPreferences:

intuserId=2425;
Stringauthtoken="abcdef345345";
Stringauthkey="qrst";
sharedPref = getBaseContext().getSharedPreferences("USER_PREFS",prefMode);
SharedPreferences.Editoreditor= vSmileSharedPreferences.edit();
editor.putString("AUTH_KEY", authkey);
editor.putString("AUTH_TOKEN", authtoken);
editor.putString("USER_ID", String.valueOf(userId));
editor.commit();

Retriving SharedPreferences values from another Activity:

Stringauthtoken="";
Stringauthkey="";
intUserId=0;
SharedPreferencessharedPref=  getBaseContext().getSharedPreferences("USER_PREFS",Context.MODE_PRIVATE);
authtoken = sharedPref.getString("AUTH_TOKEN", null);
authkey = sharedPref.getString("AUTH_KEY", null);
UserId = sharedPref.getString("USER_ID", 0);

If the SharedPreference UserID is null or empty means it will take default as 0;
