如何在ListPreference中获取当前的默认项目

Question

So I know how to get the currently selected item in a ListPreference .

I also know how to set which item will be the default .

But I couldn't find the "reverse equivalent" of ListPreference.setDefaultValue() .

Is there a way to determine, at runtime, which is the current default item ? (preferably its 0-based index in the ListPreference )

Answer 1

You can use

String value = listPreference.getValue();
int index = listPreference.findIndexOfValue(value);
