ANDROID Preferences List Preference change values dynamically

Question

I am trying to change the entryvalue of a listpreference depending on wether a checkbox is ticked or not...

    SharedPreferences sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this);{
    if(sharedPrefs.getBoolean("french", false))
    {

        Preference newsPref = (Preference) findPreference("news_feed");
        newsPref.setDefaultValue("@array/newsfeedfr");

    }
    else
    {
        Preference newsPref = (Preference) findPreference("news_feed");
        newsPref.setEntryValues("@array/newsfeed");

    }

    }

i get errors on the .setEntryValue with this:

The method setEntryValues(String) is undefined for the type Preference

Answer 1

One issue that you have is in how you're referencing your array values. @array/newsfeed is used in XML files, not Java!

You probably want to use getResources().getStringArray(R.array.newsfeed) or similar. Source.

Another issue is that setEntryValues() isn't defined for Preferences, you need to initialise as a ListPreference instead.
