java - 如何在android中的自定义 ListView 中对列表项进行排序？

Question

我正在尝试对列表项进行排序，我正在使用自定义 ListView 。在这里，我将项目存储在字符串数组中。但是在列出项目时， ListView 显示的是空项目而不是已排序的项目。但是在调试时，字符串数组以排序格式存储。如何解决？

Answer 1

 /**
    * need to sort the ArrayList based on Person’s firstName. 
   *  Here inside the Collections.sort method we are 
    * implementing the Comparator interface and overriding the compare method. 
    */

        Collections.sort(employeeList, new Comparator(){

            public int compare(Object o1, Object o2) {
                ContactInfo p1 = (ContactInfo) o1;
                ContactInfo p2 = (ContactInfo) o2;
               return p1.getEmployeeName().compareToIgnoreCase(p2.getEmployeeName());
            }

        });





        this.fav_adapter  = new FavoritesAdapter(this, R.layout.favorite_list_view, employeeList);
        setListAdapter(this.fav_adapter);





public class ContactInfo {

    private String employeeLpn;
    private String employeeName;


/**
     * Gets value for employeeLpn
     * @return the employeeLpn
     */
    public String getEmployeeLpn() {
        return employeeLpn;
    }
    /**
     * Sets the value for employeeLpn
     * @param employeeLpn the employeeLpn to set
     */
    public void setEmployeeLpn(String employeeLpn) {
        this.employeeLpn = employeeLpn;
    }
    /**
     * Gets value for employeeName
     * @return the employeeName
     */
    public String getEmployeeName() {
        return employeeName;
    }
    /**
     * Sets the value for employeeName
     * @param employeeName the employeeName to set
     */
    public void setEmployeeName(String employeeName) {
        this.employeeName = employeeName;
    }

}
