android list排序(不管list中是何种数据类型)

List<ContentValues> ls=new ArrayList<ContentValues>();
Collections.sort(ls, new ComparatorValues());


public static final class ComparatorValues implements Comparator<ContentValues>{

        @Override
        public int compare(ContentValues object1, ContentValues object2) {
            int m1=object1.getAsInteger(KEY_m);
            int m2=object2.getAsInteger(KEY_m);
            int result=0;
            if(m1>m2)
            {
                result=1;
            }else if(m1<m2)
            {
                result=-1;
            }else{

		result=0;

            }
            return result;
        }        
        
    }
