SharedPreferences return only default value

Question

So instead of creating a database, I\'m storing the data using SharedPreference.

My code is below:

   SharedPreferences.Editor editor =          


        

Answer 1

Do you use shared preferences in two different activieties of one app ?

Also try to specify preferences name, or use some Manager to handle all preferences, all this explained here

Answer 2

editor.putInt("favid"+id, 1);

what's about id is equals to 0? here you are reading starting from 1

 for (int i = 1; i < 19; i++) {

Answer 3

See docs about getPrefernces method:

Retrieve a SharedPreferences object for accessing preferences that are private to this activity.

So, if you want to share preferences between activities you should use getSharedPreferences with specified name.
