Question

I am displaying my “Settings” screen through a class that extends PreferenceFragment. I need to know when a particular setting is clicked so that I can handle the Intent to launch at runtime, as opposed to declaring in xml like this:

<PreferenceScreen
      android:title="@string/terms_conditions"
      android:summary=""
      android:layout="@layout/settings_item">
       <intent android:action="android.intent.action.VIEW"
             android:data="http://www.somecompany.com/m/EULA.aspx" />
 </PreferenceScreen>   

I need to fire a different Intent depending on other variables involved.

So, what I need is to know when the user clicks the “Terms and Conditions” within the settings fragment.

Answer 1

Have the class in which you need to know about config changes implement

SharedPreferences.onSharedPreferenceChangeListener 

and install it as a listener in your SharedPreferences via

SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(context);
prefs.registerOnSharedPreferenceChangeListener(listener);

Then handle the changes is

onSharedPreferenceChanged()

The relevant documentation is about SharedPreferences and SharedPreferences.OnSharedPreferenceChangeListener
