【中文标题】如何一次查询联系人的所有详细信息【英文标题】：How to query all the details of the Contact at once 【发布时间】：2013-11-11 09:24:11 【问题描述】：编辑：我认为重要的联系方式的列表：
1.NAME
2.PHONE NUMBER
3.EMAIL ADDRESS
4.WEBSITE
5.PHYSICAL ADDRESS
我更愿意使用预取的联系人 ID 来执行此操作...仅使用一个游标来获取所有指定的数据。我希望找到正确的查询来执行此操作：
我想一次获取联系人的所有重要详细信息，我正在使用以下代码来执行此操作：
public void getAllDataByContactId(int contactId)
Log.d(TAG, "Seriously scared it might not work");
String phoneNo="Phone disconnected";
String email="Email could not be delivered";
String website="Website 404";
String address="Number 13,Dark Street,Area 51,Bermuda Trianlge";
String name="Clint Eastwood";
int hasPhoneNumber;
String selection=ContactsContract.Data.CONTACT_ID+"=?";
String[] selectionArgs=String.valueOf(contactId);
Cursor c=context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null,selection, selectionArgs,ContactsContract.Data.TIMES_CONTACTED);
if(c!=null && c.getCount()>0)
while(c.moveToNext())
phoneNo=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d(TAG, "Phone number: "+phoneNo);
email=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS));
Log.d(TAG, "Email: "+email);
website=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Website.URL));
Log.d(TAG, "Website :"+website);
address=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS));
name=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME));
Log.d(TAG, "Name :"+name);
但是，尽管这不会引发错误，但它会显示许多行，其中包含一个空字符串，其中夹杂着实际值。如何编写一个消除噪音的查询？
我已经尝试过了，这让我得到了所有的价值：
String selection=ContactsContract.Data.CONTACT_ID+"=? AND "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=?";
String[] selectionArgs=String.valueOf(contactId),ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Website.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE;
【问题讨论】：
亲爱的你做了吗... 您是在说我需要使用多个游标来检索我需要获取的数据（电话号码、电子邮件、网站...）并将数据存储在包装器中。有没有办法通过调整文章末尾提到的选择条款来获取数据？ 从这里你得到亲爱的我关注相同的 4 联系人 但这不意味着 1 个用于手机的光标、一个用于电子邮件的光标、一个用于网站的光标等...我相信使用 SQL 可以同时显示来自各种表的数据...可以这样吗使用单个光标完成...我有方便的方法可以使用每个项目的光标获取所有详细信息。 亲爱的我只用了一个请仔细看我的代码 【参考方案1】：回答为时已晚，但也许它可以帮助将来的人。 我对这个问题的解决方案只有一个 while 循环和查询：
private void fetchContacts(ContentResolver contentResolver)
if (contentResolver == null) return;
Cursor cursor = contentResolver.query(ContactsContract.Data.CONTENT_URI,
null, null, null, null);
if (cursor == null || cursor.getCount() <= 0)
return;
String prevId = "";
String contactId = "";
PersonContact personContact = null;
while (cursor.moveToNext())
String company = "";
String columnName = cursor.getString(cursor.getColumnIndex("mimetype"));
if (columnName.equals(ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE))
company = cursor.getString(cursor.getColumnIndex("data1"));
String email = "";
if (columnName.equals(ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE))
email = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
String phone = "";
if (columnName.equals(ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE))
phone = cursor.getString(cursor.getColumnIndex("data1"));
String first = "";
String last = "";
if (columnName.equals(ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE))
first = cursor.getString(cursor.getColumnIndex("data2"));
last = cursor.getString(cursor.getColumnIndex("data3"));
if (!prevId.equals(contactId))
if (!TextUtils.isEmpty(prevId))
addFilteredList(personContact);
allContacts.put(prevId, personContact);
prevId = contactId;
personContact = new PersonContact();
else
if (personContact != null)
personContact.id = prevId;
if (TextUtils.isEmpty(personContact.company)) personContact.company = company;
if (TextUtils.isEmpty(personContact.firstName)) personContact.firstName = first;
if (TextUtils.isEmpty(personContact.lastName)) personContact.lastName = last;
if (!TextUtils.isEmpty(email) && personContact.emails.size() == 0)
personContact.emails.add(email);
if (!TextUtils.isEmpty(phone) && personContact.phoneNumbers.size() == 0)
personContact.phoneNumbers.add(phone);
contactId = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
cursor.close();
如您所见，我使用了 prevId 字段，因为 cursor.moveToNext 对一个联系人执行多次（一次用于名字和姓氏，一次用于电话等）。每次迭代后，我都会检查之前的联系人标识符和当前标识符，如果为假，我会更新 personContact 模型中的字段。
