You can do it with Collator.getInstance(Locale.CHINESE),the code:

Collections.sort(yourlist, new Comparator<String>() {
    @Override
    public int compare(Stringa1, Stringa2) {
        Collator collator = Collator.getInstance(Locale.CHINESE);
        int mySort = collator.compare(a1, a2);
        return mySort;
    }
 });

Collections.sort using your own comparator would definitely be a start. To create a comparator, have a class implement Comparator and implement its compare method. Then, instantiate an object and pass it to the Collections.sort method.

EDIT:

Approx psuedocode for the logic inside the compare method:

IF s1 isChinese && s2 isEnglish
    return -1
IF s2 isChinese && s1 isEnglish
    return 1
IF s1 isChinese && s2 isChinese 
    //implement your custom way to sort stuff
IF s1 isEnglish && s2 isEnglish 
    //implement your custom way to sort stuff

This way, your chinese words will appear at the top instead of at the bottom.

A better way is to translate it to english (see here) and then sort it using Comparator..

Use the normal sort eg:

Collections.sort(list);

If you need some custom sorting you can implement your own comparator:

Collections.sort(list, new Comparator<String>() {
    public int compare(String s1, String s2) {
         // some own compare method...
    } 
});
