1.读取带电话号码的所有联系人。
Android系统貌似没有直接取得带电话号码的联系人列表的功能。直接读取Contacts.CONTENT_URI只能读取联系人信息却得不到电话号码。如果先读取联系人列表，再通过联系人列表一个一个读取电话号码又非常慢，所以可以这样读：先从Phone.CONTENT_URI读取出电话列表，但是有可能一个人对应多个号码，这时只要合并一下就可以了，根据Contacts.SORT_KEY_PRIMARY排序，同一个人的不同号码是靠在一起的，这样合并就变得非常容易，坏处是对于没有电话号码的联系人这里是取不到的。（Contact是一个自定义类，这里没有写出来，这不是重点……）
public static void loadContacts(Context context) {
ArrayList AllContacts = new ArrayList();
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.读取最近联系人
Android可以通过查询Contacts.CONTENT_STREQUENT_URI得到最近联系人。注意这里得到的不是历史通话记录，而是系统根据通话频率自动获得的。
public static void loadStrequent() {
ArrayList StrequentContacts = new ArrayList();
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();
// 显示最近联系人和收藏的联系人
Cursor cursor = resolver.query(Contacts.CONTENT_STREQUENT_URI,
projection, null, null, null);
// 加载最近联系人，不包括收藏的联系人
//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.读取合并后的通话记录。
查询Calls.CONTENT_URI，并不能读取出具体的联系人信息，如果要知道最近通话记录，要跟已经联系人列表对照使用。
public static void loadCallLogsCombined() {
if (AllContacts.size() == 0) {
loadContacts();
}
ArrayList recentContacts = new ArrayList();
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 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 iterator = recentContacts.iterator(); iterator
.hasNext();) {
Contact con = iterator.next();
if (con.Last_Contact_Number.equals(number)) {
matched = true;
con.Times_Contacted++;
break;
}
}
if (!matched) {
match3: for (Iterator iterator = AllContacts
.iterator(); iterator.hasNext();) {
Contact con = iterator.next();
ArrayList phones = con.getPhones();
for (Iterator iterator2 = phones
.iterator(); iterator2.hasNext();) {
PhoneStruct phoneStruct = iterator2.next();
if (phoneStruct.phoneNumber.equals(number)) {
matched = true;
Contact tmpContact = con.clone();
tmpContact
.setPhones(new ArrayList());
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 match3;
}
}
}
}
}
}
cursor.close();
}
