Reset specific preferences Android

Question

I've got a number of preferences that I want to reset back to the defaults specified in my preferences xml file.

I do not want to reset all of my preferences - just a few select ones.

I've tried:

key=getResources().getString(R.string.myPref);
sharedPreferences.edit().remove(key).commit();

This clears the preference. However when my program then tries to pick the preference up

String myPref = sharedPreferences.getString(key, "");

It just returns the empty string.

How do I get the value from the XML file?

Thanks

Adding more complete code sample that I've been debugging:

//Get preferences
SharedPreferences sharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity);

//Get preference key
key=getResources().getString(R.string.myPref);

//Get preference value
String myPref = sharedPreferences.getString(key, ""); // Returns a value that has been entered by a user

//Clear preference
sharedPreferences.edit().remove(key).commit();

//Reset preferences to default values - without overwritting all
PreferenceManager.setDefaultValues(currentContext, preferences, false);

//Get preference value again
String myPref = sharedPreferences.getString(key, ""); // Returns an empty string

Answer 1

Try PreferenceManager.setDefaultValues(this, R.xml.preferences, false); This is save as the last parameter ensures that user changed entries don't get overridden.

Answer 2

getDefaultSharedPreferences(Context).setDefaultValues(this, R.xml.preference, true);

Be sure to set last argument readAgain to true.

This will force to re-read the default values. If false, this method sets the default values only if this method has never been called in the past (or if the KEY_HAS_SET_DEFAULT_VALUES in the default value shared preferences file is false). To attempt to set the default values again bypassing this check, set readAgain to true.
