排序列表在Android上复选框列 [英] Sorting a list with a checkbox column in android

问题描述

我在行包含四列的android列表视图。它可以由两列（ID，组），另外两个是一个彩色状态值和一个复选框进行排序。目前，该行正在使用比较的ID进行排序，分组然而，当我打电话通知只有这些值进行排序的颜色和复选框都没有。有没有一种方法排序基于行的名单？

添加了code的ID比较：

 公共静态类IDComparator实现比较＆LT;＆MyObject的GT; {
        @覆盖
        公众诠释比较（为MyObject LHS，RHS为MyObject）{
            如果（lhs.getID（）== NULL）{
                如果（rhs.getID（）== NULL）{
                    //等于
                    返回0;
                }其他{
                    // LHS为＆lt;
                    返回-1;
                }
            }
            如果（rhs.getID（）== NULL）{
                // LHS是＆GT;
                返回1;
            }
            //没有空
            如果（lhs.getID（）＆所述; rhs.getID（））{
                返回-1;
            }否则如果（lhs.getID（）＆GT; rhs.getID（））{
                返回1;
            }其他{
                返回0;
            }
        }
    }
 

这个方法是从这里叫做：

  Col​​lections.sort（myList上，IDComparator）;
 

解决方案

我使用Collection.sort在我的项目的排序是这样的：

  Col​​lections.sort（headerList，新的比较＆LT; HeaderVO＆GT;（）{
        @覆盖
        公众诠释比较（HeaderVO E1，E2 HeaderVO）{
              返回Double.valueOf（e2.getPNo（））的compareTo（Double.valueOf（e1.getPNo（）））。
        }
}）;
 

I have a listview in android that contains four columns in the row. It can be sorted by two columns (id, group) the other two are a color status value and a checkbox. Currently the rows are being sorted using comparators for the id, group however when I called notify only these values are sorted the color and checkbox are not. Is there a way to sort the list based on the row?

Added the code for the id comparator:

public static class IDComparator implements Comparator<MyObject> {
        @Override
        public int compare(MyObject lhs, MyObject rhs) {
            if (lhs.getID() == null) {
                if (rhs.getID() == null) {
                    //equal
                    return 0;
                } else {
                    //lhs is <
                    return -1;
                }
            }
            if (rhs.getID() == null) {
                //lhs is >
                return 1;
            }
            //neither null
            if (lhs.getID() < rhs.getID()) {
                return -1;
            } else if (lhs.getID() > rhs.getID()) {
                return 1;
            } else {
                return 0;
            }
        }
    }

This method is called from here:

 Collections.sort(myList, IDComparator);

解决方案

I am using Collection.sort for sorting like this in my project :

 Collections.sort(headerList, new Comparator<HeaderVO>() {
        @Override
        public int compare(HeaderVO e1, HeaderVO e2) {
              return Double.valueOf(e2.getPNo()).compareTo(Double.valueOf(e1.getPNo()));
        }
});
