Question

I have implemented some app preferences for my app. For strings they work great but not for boolean values. E.g.

public class MdSharedPrefs {
    public final static String PREFS_NAME = "prefs";

    public static boolean getSSFlag(Context context) {
        SharedPreferences prefs = context.getSharedPreferences(PREFS_NAME, 0);

        return prefs.getBoolean(context.getString(R.string.pref_key_ss), false);
    }

    public static void setSSFlag(Context context, boolean newValue) {
        SharedPreferences prefs = context.getSharedPreferences(PREFS_NAME, 0);
        Editor prefsEditor = prefs.edit();
        prefsEditor.putBoolean(context.getString(R.string.pref_key_ss),
                newValue);
        prefsEditor.commit();
    }

}

And this requires

<string name="pref_key_ss"></string>

in strings.xml. When I remove this line the project wont compile. But when I leave it this boolean pref does not work. When I click it and go back to main screen and then go back to prefs the value is not checked.

However for strings it works fine.

Any ideas whats wrong?

Answer 1

in my application i am using like this it’s working fine

declaration

 private static final String SUNDAY_ON = "sunday_selected";

getting

 state = prefs.getBoolean(SUNDAY_ON, false);

storing like this

 editor.putBoolean(SUNDAY_ON, value);
