编辑：我认为重要的联系方式列表：
1.NAME
2.PHONE NUMBER
3.EMAIL ADDRESS
4.WEBSITE
5.PHYSICAL ADDRESS
我更喜欢使用预先获取的contactId ...只使用一个游标来获取指定的所有数据。我最好想找到正确的查询来执行此操作：
我想立即获取联系人的所有重要细节，我使用以下代码执行此操作：
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，其中包含一个与实际值相互关联的空字符串。如何编写一个可以消除噪音的查询？
我试过这个，这让我得到了所有的价值观：
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};
可能不是最好的解决方案。但这就是我实现它的方式。

回答太晚了，但也许它可以帮助将来的某个人。这个问题的解决方案只有一个循环和查询：
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();
}
正如您所看到的，我使用了prevId字段，因为cursor.moveToNext为一个联系人执行了几次（一次为姓名，一次为电话等）。在每次迭代之后，我使用当前标识符检查先前的联系人标识符，如果为false，则更新personContact模型中的字段。
