Access application context in a storage class in Android

I have an app on Android 4.0. It uses the PreferenceManager class to -- among other things -- let the user specify how many decimal places of a number to show.

mPreferences = PreferenceManager.getDefaultSharedPreferences(this);

Generally I have no problem getting the app context in order to access the Preference Manager. My problem is that I have a class (let's call it Record) that isn't subclassing anything that has the app context; it's just a storage class, but it does have a field "NumDecPlaces". Right now, when I instantiate the class from within my app I just pass in the user's #dec places preference. It would be nice if Record could access the Preference manager directly. I suppose I could always instantiate Record with a pointer to the context from which it was created, but that's a lot to remember ;-)

So right now Record subclasses nothing. Any recommendations on what I can do to it to allow it to see the app context?

Thanks!

Solution

You could pass the Context object in the constructor. So whenever you try to use that class it will ask you pass a Context object and then use that to get SharedPreferences

For eg.

public Record(Context context)
{
  mContext = context;

  mPreferences = PreferenceManager.getDefaultSharedPreferences(mContext)
}
