Answer 1

Take a look at that post :

To read these preferences from code, we should create a getPrefs() method, which we can call in the onStart() method. When we call it in the onStart() method instead of onCreate(), we can be sure that the preferences load when we have set them and returned to our main activity,

private void getPrefs() {
                // Get the xml/preferences.xml preferences
                SharedPreferences prefs = PreferenceManager
                                .getDefaultSharedPreferences(getBaseContext());
                CheckboxPreference = prefs.getBoolean("checkboxPref", true);
                ListPreference = prefs.getString("listPref", "nr1");
                editTextPreference = prefs.getString("editTextPref",
                                "Nothing has been entered");
                ringtonePreference = prefs.getString("ringtonePref",
                                "DEFAULT_RINGTONE_URI");
                secondEditTextPreference = prefs.getString("SecondEditTextPref",
                                "Nothing has been entered");
                // Get the custom preference
                SharedPreferences mySharedPreferences = getSharedPreferences(
                                "myCustomSharedPrefs", Activity.MODE_PRIVATE);
                customPref = mySharedPreferences.getString("myCusomPref", "");
        }

Answer 2

make your preference activity implement onPreferenceChangeListener and then you need to find the preference by its key in onCreate and register the listener.
