源碼來自我的一個撥號應用：https://github.com/NashLegend/QuicKid
1.讀取帶電話號碼的所有聯繫人。
Android系統貌似沒有直接取得帶電話號碼的聯繫人列表的功能。直接讀取Contacts.CONTENT_URI只能讀取聯繫人信息卻得不到電話號碼。如果先讀取聯繫人列表，再通過聯繫人列表一個一個讀取電話號碼又非常慢，所以可以這樣讀：先從Phone.CONTENT_URI讀取出電話列表，但是有可能一個人對應多個號碼，這時只要合併一下就可以了，根據Contacts.SORT_KEY_PRIMARY排序，同一個人的不同號碼是靠在一起的，這樣合併就變得非常容易，壞處是對於沒有電話號碼的聯繫人這裏是取不到的。（Contact是一個自定義類，這裏沒有寫出來，這不是重點……）
public static void loadContacts(Context context) {
ArrayList<Contact> AllContacts = new ArrayList<Contact>();
ContentResolver resolver = context.getContentResolver();
// 要使用RawContacts.CONTACT_ID而不是Contacts.CONTACT_ID
String[] PROJECTION = {
RawContacts.CONTACT_ID, Contacts.DISPLAY_NAME,
Contacts.LOOKUP_KEY, Contacts.PHOTO_THUMBNAIL_URI,
Phone.NUMBER, Phone.TYPE, Contacts.STARRED
};
Cursor cursor = resolver.query(Phone.CONTENT_URI, PROJECTION, null,
null, Contacts.SORT_KEY_PRIMARY);
String preLookupKey = "";
Contact preContact = null;
if (cursor.moveToFirst()) {
do {
long contractID = cursor.getInt(0);
String displayName = cursor.getString(1);
String lookupKey = cursor.getString(2);
String photoUri = cursor.getString(3);
boolean starred = cursor.getInt(6) == 1;
if (lookupKey.equals(preLookupKey) && preContact != null) {
preContact.addPhone(cursor.getString(4), cursor.getInt(5));
} else {
Contact contact = new Contact();
contact.setContactId(contractID);
contact.setName(displayName);
contact.setLookupKey(lookupKey);
contact.setPhotoUri(photoUri);
contact.addPhone(cursor.getString(4), cursor.getInt(5));
contact.setStarred(starred);
AllContacts.add(contact);
preLookupKey = lookupKey;
preContact = contact;
}
} while (cursor.moveToNext());
} else {
// No Phone Number Found
}
cursor.close();
}2.讀取最近聯繫人
Android可以通過查詢Contacts.CONTENT_STREQUENT_URI得到最近聯繫人。注意這裏得到的不是歷史通話記錄，而是系統根據通話頻率自動獲得的。
public static void loadStrequent() {
ArrayList<Contact> StrequentContacts = new ArrayList<Contact>();
String[] projection = { Contacts._ID, Contacts.DISPLAY_NAME,
Contacts.LOOKUP_KEY, Contacts.PHOTO_THUMBNAIL_URI,
Contacts.TIMES_CONTACTED, Contacts.LAST_TIME_CONTACTED,
Contacts.STARRED, Contacts.PHOTO_ID };
ContentResolver resolver = AppApplication.globalApplication
.getContentResolver();
// 顯示最近聯繫人和收藏的聯繫人
Cursor cursor = resolver.query(Contacts.CONTENT_STREQUENT_URI,
projection, null, null, null);
// 加載最近聯繫人，不包括收藏的聯繫人
//Cursor cursor = resolver.query(
// Uri.withAppendedPath(Contacts.CONTENT_URI, "frequent"),
// projection, null, null, null);
while (cursor.moveToNext()) {
Contact contact = new Contact();
long contractID = cursor.getInt(0);
String displayName = cursor.getString(1);
String lookupKey = cursor.getString(2);
String photoUri = cursor.getString(3);
int TIMES_CONTACTED = cursor.getInt(4);
long LAST_TIME_CONTACTED = cursor.getLong(5);
boolean starred = cursor.getInt(6) == 1;
contact.setContactId(contractID);
contact.setName(displayName);
contact.setLookupKey(lookupKey);
contact.setPhotoUri(photoUri);
contact.setStarred(starred);
contact.Times_Contacted = TIMES_CONTACTED;
contact.Last_Time_Contacted = LAST_TIME_CONTACTED;
StrequentContacts.add(contact);
}
cursor.close();
// notify
}3.讀取合併後的通話記錄。
查詢Calls.CONTENT_URI，並不能讀取出具體的聯繫人信息，如果要知道最近通話記錄，要跟已經聯繫人列表對照使用。
public static void loadCallLogsCombined() {
if (AllContacts.size() == 0) {
loadContacts();
}
ArrayList<Contact> recentContacts = new ArrayList<Contact>();
String[] projection = {
Calls._ID, Calls.TYPE, Calls.CACHED_NAME,
Calls.CACHED_NUMBER_TYPE, Calls.DATE, Calls.DURATION,
Calls.NUMBER
};
ContentResolver resolver = AppApplication.globalApplication
.getContentResolver();
Cursor cursor = resolver.query(Calls.CONTENT_URI, projection, null,
null, Calls.DEFAULT_SORT_ORDER);
while (cursor.moveToNext()) {
long callID = cursor.getInt(0);
int callType = cursor.getInt(1);
String name = cursor.getString(2);
int numberType = cursor.getInt(3);
long date = cursor.getLong(4);
int duration = cursor.getInt(5);
String number = cursor.getString(6);
if (TextUtils.isEmpty(name)) {
boolean matched = false;
for (Iterator<Contact> iterator = recentContacts.iterator(); iterator
.hasNext();) {
Contact con = iterator.next();
if (con.Last_Contact_Number.equals(number)) {
matched = true;
con.Times_Contacted++;
break;
}
}
if (!matched) {
Contact tmpContact = new Contact();
tmpContact.Times_Contacted = 1;
tmpContact.Last_Contact_Call_ID = callID;
tmpContact.Last_Contact_Call_Type = callType;
tmpContact.Last_Contact_Number = number;
tmpContact.Last_Contact_Phone_Type = numberType;
tmpContact.Last_Time_Contacted = date;
tmpContact.Last_Contact_Duration = duration;
recentContacts.add(tmpContact);
}
} else {
boolean matched = false;
for (Iterator<Contact> iterator = recentContacts.iterator(); iterator
.hasNext();) {
Contact con = iterator.next();
if (con.Last_Contact_Number.equals(number)) {
matched = true;
con.Times_Contacted++;
break;
}
}
if (!matched) {
match2: for (Iterator<Contact> iterator = AllContacts
.iterator(); iterator.hasNext();) {
Contact con = iterator.next();
ArrayList<PhoneStruct> phones = con.getPhones();
for (Iterator<PhoneStruct> iterator2 = phones
.iterator(); iterator2.hasNext();) {
PhoneStruct phoneStruct = iterator2.next();
if (phoneStruct.phoneNumber.equals(number)) {
matched = true;
Contact tmpContact = con.clone();
tmpContact
.setPhones(new ArrayList<Contact.PhoneStruct>());
tmpContact.Times_Contacted = 1;
tmpContact.Last_Contact_Call_ID = callID;
tmpContact.Last_Contact_Call_Type = callType;
tmpContact.Last_Contact_Number = number;
tmpContact.Last_Contact_Phone_Type = numberType;
tmpContact.Last_Time_Contacted = date;
tmpContact.Last_Contact_Duration = duration;
recentContacts.add(tmpContact);
break match2;
}
}
}
}
}
}
cursor.close();
}
