You can sort any collection in java by this code:

Collections.sort(mList, new Comparator<YourModel>(){
    public int compare(YourModel obj1, YourModel obj2) {
        return Integer.valueOf(obj1.ID).compareTo(Integer.valueOf(obj2.ID));
        // Or you can compare any field of your object
    }
});

for more detail go to docs

thanks. Actually I was ignorant about Collections.sort can be used this way. I was discovered my own method to sort by Index according to ID. – Koyas Jun 17 '19 at 17:06
