sorting - How to sort a cursor with variables in android? -


i have listview (in listframent) cursoradapter shows different names of places. @ begining, list sorted names (using order_by in query).

now, have added item_row.xml textview containing distance of place user's position latitude/longitude of each place , locationmanager. , sort list of places distance (from nearest farthest).

the problem calculate distance outside "sql environment", , there no methods sort cursor/listview/adapter...

any ideas ?

use collections.sort(list, comparator) custom comparator.

example using class sorting sum of both integer fields:

import java.util.arraylist; import java.util.collections; import java.util.comparator; import java.util.list;  class {     final string name;     final int somenumber;     final int someothernumber;      a(final string name, final int a, final int b) {         this.name = name;         this.somenumber = a;         this.someothernumber = b;     }      @override     public string tostring() {         return this.name;     } }  class yourcomparator implements comparator<a> {     @override     public int compare(a o1, o2) {         final int sumo1 = o1.somenumber + o1.someothernumber;         final int sumo2 = o2.somenumber + o2.someothernumber;         return (sumo1 - sumo2);     } }  public class main {     public static void main(final string args[]) {         final list<a> listofas = new arraylist<a>();         listofas.add(new a("three", 1, 2));         listofas.add(new a("two", 1, 1));         listofas.add(new a("ten", 3, 7));         listofas.add(new a("five", 3, 2));         collections.sort(listofas, new yourcomparator());         system.out.println(listofas);     } }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
