Sort key-value pair of a Bundle in android

Question

I have a list of key-value pairs in a Bundle

params.keySet()

which needs to be sorted alphabetically on the key column.

I tried the long way of extracting the key-value pairs and sorting them using

Collections.sort(list)

and putting it back inside a new Bundle.

But when I call params.keySet(). They come to un-sorted again. Any ideas. Is their an easy way?

Answer 1

Bundle is backed up by a HashMap , so it does not guarantee the order of keys. You'll have to reconsider the logic in your app to break the dependency on the order of the keys in the Bundle.

Answer 2

public Set<String> keySet () Set only guarantees no duplicates but not order.

For your requirement, you can use some subclass of java.util.SortedMap instead of Bundle .
