Android สอบถามการเรียงลำดับ Sort ข้อมูลจากน้อยไปมากใน ArrayList<HashMap> ..ครับ!!

import java.util.ArrayList;
import java.util.Collections;
 
public class SortJavaArrayListExample {
 
  public static void main(String[] args) {
   
    //create an ArrayList object
    ArrayList arrayList = new ArrayList();
   
    //Add elements to Arraylist
    arrayList.add("1");
    arrayList.add("3");
    arrayList.add("5");
    arrayList.add("2");
    arrayList.add("4");
 
    /*
      To sort an ArrayList object, use Collection.sort method. This is a
      static method. It sorts an ArrayList object's elements into ascending order.
    */
    Collections.sort(arrayList);
   
    //display elements of ArrayList
    System.out.println("ArrayList elements after sorting in ascending order : ");
    for(int i=0; i<arrayList.size(); i++)
      System.out.println(arrayList.get(i));
 
  }
}
 
/*
Output would be
ArrayList elements after sorting in ascending order :
1
2
3
4
5
*/
