Reload Preferences in PreferenceActivity on Resume

Question

In my app, some settings can possibly be changed while the PreferenceActivity is not open, and an issue I\'m running into is that addPreferencesFromResour

Answer 1

I had a similar problem. Failing to find a simple way to make my PreferenceActivity refresh itself, my solution was to add this to my PreferenceActivity:

/**
 * Called when activity leaves the foreground
 */
protected void onStop() {
    super.onStop();
    finish();
}

This will cause the Prefs screen to reload from SharedPreferences next time it is started. Needless to say, this approach won't work if you want to be able to go back to your preferences screen by using the back button.
