笔记72 | 将姓放在名的后面，排序按姓氏首字母排列的修改笔记

需求

更改之后

分析

只看“ A”皇阿玛 “，在我的电话簿中A”是姓，皇阿玛是名，需求是将名显示在前，姓在后，排列顺序要按姓来排列。之前是直接修改 switch_name_x的返回字符 returnrecord.get(i).getGivenName()+" "+record.get(i).getFamilyName();强制完成姓名调换，后来测试组反馈说排序没有按姓氏排，而是按照名的首字母排，赶紧查阅代码，发现之前电话簿是按照“姓+名”的组合字符的首字母进行排列，想想，那么只要在排列的方法中只对姓式的首字母进行排列即可，于是就修改了以下代码就完成需求！

修改

修改之前的主要代码：

private ArrayList<HashMap<String, String>> mPBList;private List<SortModel> SourceDateList;HashMap<String, String> map = new HashMap<String, String>();                    map.put("item_phonebook_name", getString(R.string.bt_notsupport_download_phonebook));                    map.put("item_phonebook_number", "");                    mPBList.add(map);                SourceDateList= filledData(mPBList);                                Collections.sort(SourceDateList, pinyinComparator);                mAdapter.notifyDataSetChanged();    for (int i = 0; i < record.size(); i++) {                            HashMap<String, String> map = new HashMap<String, String>();                                                    map.put("item_phonebook_name",switch_name_x(record,i));                            map.put("item_phonebook_number", record.get(i).getNumber());                            mPBList.add(map);                        }private List<SortModel> filledData(ArrayList<HashMap<String, String>> phoneList){            List<SortModel> mSortList = new ArrayList<SortModel>();            if(phoneList.size()==0)return mSortList;            for(int i=0; i<phoneList.size(); i++){                SortModel sortModel = new SortModel();                sortModel.setName(phoneList.get(i).get("item_phonebook_name").trim());                sortModel.setPhoneName(phoneList.get(i).get("item_phonebook_number").trim()); String pinyin = characterParser.getSelling(phoneList.get(i).get("item_phonebook_name").trim());                if(pinyin==null||pinyin.length()==0)pinyin="unknow";                String sortString = pinyin.substring(0, 1).toUpperCase();                if(sortString.matches("[A-Z]")){                    sortModel.setSortLetters(sortString.toUpperCase());                }else{                    sortModel.setSortLetters("#");                }                mSortList.add(sortModel);            }            return mSortList;        }        public String switch_name_x(List<PBRecord> record,int i)        {           return record.get(i).getFamilyName() + " " + record.get(i).getGivenName();        }

修改之后的代码（其中只修改了 filledData和 switch_name_x方法）：

        private List<SortModel> filledData(ArrayList<HashMap<String, String>> phoneList){            List<SortModel> mSortList = new ArrayList<SortModel>();            if(phoneList.size()==0)return mSortList;            for(int i=0; i<phoneList.size(); i++){                SortModel sortModel = new SortModel();                sortModel.setName(phoneList.get(i).get("item_phonebook_name").trim());                sortModel.setPhoneName(phoneList.get(i).get("item_phonebook_number").trim());                String pinyin = characterParser.getSelling(record_test.get(i).getFamilyName()).trim();                if(pinyin==null||pinyin.length()==0)pinyin="unknow";                String sortString = pinyin.substring(0, 1).toUpperCase();                if(sortString.matches("[A-Z]")){                    sortModel.setSortLetters(sortString.toUpperCase());                }else{                    sortModel.setSortLetters("#");                }                mSortList.add(sortModel);            }            return mSortList;        }                    List<PBRecord> record_test = new ArrayList<PBRecord>();        public String switch_name_x(List<PBRecord> record,int i)        {            record_test = record;            return record.get(i).getGivenName()+" "+ record.get(i).getFamilyName();        }}
