How to get a preference value in preference fragment

Question

I want to show the value of preferences in a custom preference screen. For this I need to get the values, in this case strings, within the preference fragment. In non fragments (activities) I get the values with e.g. final SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(this); and get the string with String phonenumber = prefs.getString("preference_name", null); but in the preference fragment getDefaultSharedPreferences is not applicable for preference fragment.

Any idea how to solve this?

Here's my code snippet:

public class PreferencesFragment extends PreferenceFragment implements
    OnSharedPreferenceChangeListener {

TextView tvusername, tvphonenumber;     

@Override
   public void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     addPreferencesFromResource(R.xml.preferences);
     getPreferenceScreen().getSharedPreferences()
            .registerOnSharedPreferenceChangeListener(this);

     final SharedPreferences prefs = PreferenceManager
            .getDefaultSharedPreferences(this);


    // entering preference phonenumber in text view
            String phonenumber = prefs.getString("phonenumber", null);
            ;
            tvphonenumber.setText(phonenumber);

    // entering preference username in text view
            String username = prefs.getString("username", null);
            ;
            tvusername.setText(username);

}

Solution

In onActivityCreated (It's the time when the activity is created) of your fragment class, you do

Context hostActivity = getActivity();
SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(hostActivity);

That's how you access the hostActivity from the attached fragment.
