android2.0contacts的一些方法

依次浏览你的电话本联系人

Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,  
    null, null, null, null);  
  while (cursor.moveToNext()) {  
   String contactId = cursor.getString(cursor.getColumnIndex(  
     ContactsContract.Contacts._ID));  
   String hasPhone = cursor.getString(cursor.getColumnIndex(  
     ContactsContract.Contacts.HAS_PHONE_NUMBER));  
   if (Boolean.parseBoolean(hasPhone)) {  
                // You know have the number so now query it like this 
    Cursor phones = getContentResolver().query(  
      ContactsContract.CommonDataKinds.Phone.CONTENT_URI,  
      null,  
      ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId,  
      null, null);  
    while (phones.moveToNext()) {  
     String phoneNumber = phones.getString(  
       phones.getColumnIndex(  
         ContactsContract.CommonDataKinds.Phone.NUMBER));                  
    }  
    phones.close();  
   }  
   Cursor emails = getContentResolver().query(  
     ContactsContract.CommonDataKinds.Email.CONTENT_URI,  
     null,  
     ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId,  
     null, null);  
   while (emails.moveToNext()) {  
                // This would allow you get several email addresses  
    String emailAddress = emails.getString(  
      emails.getColumnIndex(  
        ContactsContract.CommonDataKinds.CommonDataColumns.DATA));  
   }  
   emails.close();  
  }  
  cursor.close(); 

 

得到电话本中的姓名和号码

Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); 
 
while(people.moveToNext()) { 
 int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME); 
     String contact = people.getString(nameFieldColumnIndex); 
 int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER); 
     String number = people.getString(nameFieldColumnIndex); 
} 
 
people.close(); 

如果你想得到一些 notes 

private String getNote(long contactId) {  
  String note = null;  
  String[] columns = new String[]  
                                   { ContactsContract.CommonDataKinds.Note.NOTE };  
  String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";  
  String[] whereParameters = new String[]{Long.toString(contactId),  
    ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE};  
  Cursor contacts = getContentResolver().query  
  (ContactsContract.Data.CONTENT_URI, projection, where,  
    whereParameters, null);  
  if (contacts.moveToFirst()) {  
   rv = contacts.getString(0);  
  }  
  contacts.close();  
  return note;  
 }
