Access text of EditTextPreference from Fragment

I've got a Preferenceactivity with a EditTextPreference.

What I'm looking for is the command to access the inserted text of the EditTextPreference from a fragment.

What I have so far:

SharedPreferences preferences = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE);
        String name = preferences.getString("edit_text_preference_name", "Default");

I allways get "Default" instead of my actual inserted text from the EditTextPreference.

Thanks in Advance.

Edit:

from SettingsActivity.java

 @TargetApi(Build.VERSION_CODES.HONEYCOMB)
    public static class BarcodePreferenceFragment extends PreferenceFragment {
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            addPreferencesFromResource(R.xml.pref_barcode);
            setHasOptionsMenu(true);

            bindPreferenceSummaryToValue(findPreference("edit_text_preference_barcode"));
            bindPreferenceSummaryToValue(findPreference("edit_text_preference_name"));
        }
}

pref.xml

<EditTextPreference
        android:capitalize="words"
        android:defaultValue="@string/pref_default_display_name"
        android:key="edit_text_preference_name"
        android:maxLines="1"
        android:selectAllOnFocus="true"
        android:singleLine="true"
        android:title="@string/pref_default_display_name" />

From the documentation of PreferenceFragment:

To retrieve an instance of SharedPreferences that the preference hierarchy in this fragment will use, call getDefaultSharedPreferences(android.content.Context) with a context in the same package as this fragment.

This means that the PreferenceFragment saves the values to the default shared preferences which leaves you two options:

Option 1 - Use the default SharedPreferences to retrieve the saved value

It's pretty simple, you need to call the PreferenceManager's getDefaultSharedPreferences(...) static method to access the default shared prefs. So instead of

SharedPreferences preferences = this.getActivity().getSharedPreferences("pref", Context.MODE_PRIVATE);
String name = preferences.getString("edit_text_preference_name", "Default");

do

// use getActivity() instead of getContext() if you're using the framework Fragment API and min SDK is lower than 23
SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getContext());
String name = preferences.getString("edit_text_preference_name", "Default");

Option 2 - Set your PreferenceFragment to use named shared prefs

You can set the name of the used shared prefs in your BarcodePreferenceFragment's onCreate(...) method by calling setSharedPreferencesName(...) on the belonging PreferenceManager:

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getPreferenceManager().setSharedPreferencesName("pref");
    // the rest of your code
}
