Android 獲取系統聯繫人並排序

主要通過ContactsContract.CommonDataKinds.Phone.CONTENT_URI快速讀取全部數據，直接讀取數據庫中的數據並按拼音排序（不過按拼音排序只支持api11以上的）

讀取名字使用了contact表中的顯示

沒怎麼寫過文章就直接上代碼了

    public List<SysContact> queryContactsQuicly() {
       Map<Integer, String> IdNameMap = new HashMap<Integer, String>();
       // 讀取所有姓名和id
       long begintime = System.currentTimeMillis();
       Cursor cursor = MyApp.myApp.getContentResolver().query(
               ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
       if ((cursor != null) && (cursor.getCount() > 0)) {
           cursor.moveToFirst();
           int total = cursor.getCount();
           Log.i("vvt", "讀取所有姓名和id total:" + total);
           int displayNameIndex = cursor
                   .getColumnIndex(PhoneLookup.DISPLAY_NAME);
           int contactIdIndex = cursor
                   .getColumnIndex(ContactsContract.Contacts._ID);
           cursor.moveToFirst();
           for (int i = 0; i < total; i++) {
               String displayName = cursor.getString(displayNameIndex);
               int cid = cursor.getInt(contactIdIndex);
               // o.i("vvt","getContact_compare displayname:"+displayName+" id:"+cid);
               IdNameMap.put(cid, displayName);
               cursor.moveToNext();
           }
       }
       cursor.close();
       long endtime0 = System.currentTimeMillis();
       Log.i("vvt", "讀取所有name use：" + (endtime0 - begintime) + "毫秒");

這是用到的bean

public class SysContact {
   private int contactid ;


   public int getContactid() {
       return contactid;
   }

   public void setContactid(int contactid) {
       this.contactid = contactid;
   }

   private String Name = "";
   private String Phone = "";
   private String HomePhone = "";
   private String Company = "";
   private String pinyin = "";
   private String sortkey = "";
   private HashSet<String> phoneList =new HashSet<String>() ;
   public String getSortkey() {
       return sortkey;
   }

   public void setSortkey(String sortkey) {
       this.sortkey = sortkey;
   }

   public String getName() {
       return Name;
   }

   public void setName(String name) {
       Name = name;
   }

   public String getPhone() {
       return Phone;
   }

   public void setPhone(String phone) {
       Phone = phone;
   }

   public String getHomePhone() {
       return HomePhone;
   }

   public void setHomePhone(String homePhone) {
       HomePhone = homePhone;
   }

   public String getCompany() {
       return Company;
   }

   public void setCompany(String company) {
       Company = company;
   }

   public String getPinyin() {
       return pinyin;
   }

   public void setPinyin(String pinyin) {
       this.pinyin = pinyin;
   }
   public void addNum(String num){
       if(TextUtils.isEmpty(num)) return;
       phoneList.add(num);
   }
}
