Answer 1

Place preferences.xml in res/xml

In your activity that extends PreferenceActivity you do something like this in onCreate().

ListPreference listPreferenceCategory = (ListPreference) findPreference("default_category");
if (listPreferenceCategory != null) {
    ArrayList categoryList = getCategories();
    CharSequence entries[] = new String[categoryList.size()];
    CharSequence entryValues[] = new String[categoryList.size()];
    int i = 0;
    for (Category category : categoryList) {
        entries[i] = category.getCategoryName();
        entryValues[i] = Integer.toString(i);
        i++;
    }
    listPreferenceCategory.setEntries(entries);
    listPreferenceCategory.setEntryValues(entryValues);
}
