Question

I’ve got an Android preference activity where the layout is connected directly to my peference key/value pairs, ex:

<EditTextPreference
     android:key="timeout"
     android:defaultValue="timeout"
     android:title="Timeout"
     android:summary="Timeout (ms)"
     android:dialogTitle="Timeout (ms)" />

I need to change this somehow so that the display function (and only the display) is in seconds. Theoretically I could change it so that the storage and retrivial of the value use seconds, but that happens far too often, so I dont want to change that if I can avoid it.

The activities/services that make up my app all pull directly from the Android preferences, ex:

SharedPreferences settings = PreferenceManager.getDefaultSharedPreferences(ctx);
String s = settings.getString("timeout", ctx.getString(R.string.timeout));

So – what’s the best way to change the display function for the preference, while still storing the values in milliseconds?

I think, android is saving the value of a EditTextPreference using the setText() method. So you could use a custom View extending EditTextPreference and modify setText().
