Xamarin android Read Contacts and Numbers - android

I know to retrieve the names of contacts that's code below. But what should I change in this code to also have the numbers of phone associated with the contact list?
var uri = ContactsContract.Contacts.ContentUri;
string[] projection = { ContactsContract.Contacts.InterfaceConsts.Id,
ContactsContract.Contacts.InterfaceConsts.DisplayName };
var cursor = ManagedQuery(uri, projection, null, null, null);
var contactList = new List<string>();
if (cursor.MoveToFirst())
{
do
{
String phoneNumber = cursor.GetString(cursor.GetColumnIndex(ContactsContract.CommonDataKinds.Phone.Number));
contactList.Add(cursor.GetString(
cursor.GetColumnIndex(projection[1])));
} while (cursor.MoveToNext());
}

I came across your question while I recently wrote a similar code. The only thing you need in order to retrieve phone numbers, is to:
Make another query to Uri
ContactsContract.CommonDataKinds.Phone.ContentUri;
Set projection to include ContactsContract.CommonDataKinds.Phone.Number; and
Select based on id, i.e. selection parameter should include "_id = " +
contactId
Your query should look like this:
string[] projection = { ontactsContract.CommonDataKinds.Phone.Number };
string selection = "_id = " + contactId;
var cursor = ContentResolver.Query(ContactsContract.CommonDataKinds.Phone.ContentUri, projection, selection, null, null);
This query will bring you phone numbers for a contact id but in code below, due to performance issues, I just made one call for all phone numbers and then assign each contract their numbers. Hope it helps.
private List<Contact> GetContactList()
{
List<Contact> contacts = new List<Contact>();
string[] projection = {
ContactsContract.Contacts.InterfaceConsts.Id,
ContactsContract.Contacts.InterfaceConsts.DisplayName,
ContactsContract.Contacts.InterfaceConsts.PhotoUri
};
var uri = ContactsContract.Contacts.ContentUri;
ICursor cursor = ContentResolver.Query(uri, projection, null, null, null);
if (cursor.MoveToFirst())
{
do
{
string id = cursor.GetString(cursor.GetColumnIndex(projection[0]));
string name = cursor.GetString(cursor.GetColumnIndex(projection[1]));
string photoUri = cursor.GetString(cursor.GetColumnIndex(projection[2]));
contacts.Add(new Contact() { Id = long.Parse(id), DisplayName = name, PhotoUri = photoUri });
} while (cursor.MoveToNext());
GetContactPhoneNumber(contacts);
}
return contacts;
}
private async void GetContactPhoneNumber(List<Contact> list)
{
string[] projection =
{
ContactsContract.CommonDataKinds.Phone.Number,
ContactsContract.CommonDataKinds.Phone.InterfaceConsts.ContactId
};
var cursor = ContentResolver.Query(ContactsContract.CommonDataKinds.Phone.ContentUri, projection, null, null, null);
if (cursor.Count > 0)
{
await Task.Factory.StartNew(() =>
{
do
{
try
{
string id = cursor.GetString(cursor.GetColumnIndex(projection[1]));
string phoneNumber = cursor.GetString(cursor.GetColumnIndex(projection[0]));
Contact contact = list.Where(c => c.Id == long.Parse(id)).FirstOrDefault();
contact.PhoneNumber = phoneNumber;
}
catch
{
}
} while (cursor.MoveToNext());
cursor.Close();
});
}
}

How to search for contacts in android with partial phone number

I am trying to do fuzzy search of contacts in my android application with partial phone number, with below code. But my search function always ends in no result.
For example,
I have contact with phone number 1234567890 with name as "example".
fuzzySearch("4567"); should have return with contact named "example".
Can some please point me where am I wrong? I have checked here. But ended in run-time sql query error.
public ArrayList<Contact> fuzzySearch(String match) {
private static final String SELECTION = Phone.NUMBER + " LIKE ? COLLATE NOCASE";
Uri uri = Uri.withAppendedPath(ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI, Uri.encode(match));
String[] projectionFields = new String[]{ContactsContract.Contacts._ID, Phone.NUMBER};
CursorLoader cursorLoader = null;
ArrayList<Contact> listContacts = new ArrayList<>();
if(match.trim().length() == 0){
return listContacts;
}else {
cursorLoader = new CursorLoader(context, uri, projectionFields, SELECTION, new String[]{"%"+match+"%"}, Phone.NUMBER);
}
Cursor c = cursorLoader.loadInBackground();
final Map<String, Contact> contactsMap = new HashMap<>(c.getCount());
if (c.moveToFirst()) {
int idIndex = c.getColumnIndex(ContactsContract.Contacts._ID);
int nameIndex = c.getColumnIndex(Phone.NUMBER);
do {
String contactId = c.getString(idIndex);
String contactDisplayName = c.getString(nameIndex);
Contact contact = new Contact(contactId, contactDisplayName);
contactsMap.put(contactId, contact);
listContacts.add(contact);
} while (c.moveToNext());
}
c.close();
return listContacts;
}
use PhoneLookup instead of phone.
because you already encode the search key into the URL, you don't need SELECTION, remove it.
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode(match));
Cursor cur = resolver.query(uri, new String[]{PhoneLookup.DISPLAY_NAME,PhoneLookup.NUMBER, PhoneLookup.CONTACT_ID}, null, null, null);

Filter Contact with prefix number

I have function to load all contact number in android, and now i want to filter all contact number with prefix "0878","0877","0817" so contact number with that prefix will be loaded, and here my current code :
private void loadContact(){
ContentResolver cr = applicationContext.getContentResolver();
String [] PROJECTION = ContactsQuery.PROJECTION;
Cursor cursor = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
PROJECTION,
null,
null,
null
);
while (cursor.moveToNext()) {
//String name = cursor.getString(ContactsQuery.DISPLAY_NAME);
String lookUpKey = cursor.getString(ContactsQuery.LOOKUP_KEY);
loadContactDetail(lookUpKey);
}
cursor.close();
}
private void loadContactDetail(String lookUpKey){
ContentResolver cr = applicationContext.getContentResolver();
String [] COLS = {ContactsContract.CommonDataKinds.Phone.NUMBER};
Cursor cursor = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, COLS,
ContactsContract.Data.LOOKUP_KEY + " = ?",
new String[]{lookUpKey},
null
);
while (cursor.moveToNext()) {
String phone = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String formatted = Util.formatMSISDN(phone);
if(formatted != null)
contactsSet.add(formatted);
}
cursor.close();
}
Try this.
while (cursor.moveToNext()) {
String phone = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
String formatted = Util.formatMSISDN(phone);
if(formatted != null){
if(formatted.startsWith("0878") || formatted.startsWith("0877") || formatted.startsWith("0817"))
contactsSet.add(formatted);
}
}
cursor.close();
Check out the sourceString.contains(CharSequence) method.

Android - Search contacts with different formats of number

In my application I try to search a contact using the phonenumber. The phonenumber I am searching with is always in the same format ('123456789' for example).
But the following code retrieves not all contacts I expected.
The main issue might be the different format of phonenumbers in my phone: some contacts are saved with '+12 345 6789', the other with '0123 456789'.
Although I tried ContactsContract.PhoneLookup.NORMALIZED_NUMBER my code retrieves only the contacts saved with phonenumbers in the '123456789'-format.
private String getContactDetails(Context context, String number) {
String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID,
ContactsContract.PhoneLookup.LOOKUP_KEY};
int len = number.length();
Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number.substring(len-7)));
String selection = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN) {
selection = ContactsContract.PhoneLookup.NORMALIZED_NUMBER + " LIKE %" + number.substring(len-7) + "%";
}
Cursor cursor = context.getContentResolver().query(contactUri, projection, selection, null, null);
String name = null;
if(cursor != null) {
if (cursor.moveToFirst()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
cursor.close();
}
return name;
}
Don't use both PhoneLookup.CONTENT_FILTER_URI with selection, CONTENT_FILTER_URIs are used to search for data using the URI itself, and should not get any selection.
The PhoneLookup.NORMALIZED_NUMBER column is for getting the result back in an e164 format, not for querying.
Try this:
Uri uri = Uri.withAppendedPath(PhoneLookup.CONTENT_FILTER_URI, Uri.encode("123456789"));
String[] projection = new String[] { PhoneLookup.NUMBER, PhoneLookup.NORMALIZED_NUMBER };
Cursor c = getContentResolver().query(uri, projection, null, null, null);
if (c != null) {
if (c.moveToFirst()) {
String number = c.getString(0);
String e164_number = c.getString(1);
Log.d(TAG, "number=" + number + ", e164=" + e164_number);
} else {
Log.d(TAG, "couldn't find number");
}
}
c.close();

Android: How to get contact DisplayName by contact _ID?

folks!
Look I broke my mind with problem -
how get display_name from ContactContract via _ID I got earlier???
Here is the code:
public static long getId(Context context, String number) {
long id = 0;
String displayName;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.PhoneLookup.DISPLAY_NAME,
ContactsContract.PhoneLookup._ID};
// encode the phone number and build the filter URI
final Uri contactUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
// query time
final Cursor cursor = context.getContentResolver().query(contactUri, projection, null, null, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
// HERE IS GOOD _ID!
id = cursor.getLong(cursor.getColumnIndex(ContactsContract.PhoneLookup._ID));
Log.d("_TAG_", displayName);
{
//
// v. N-1
//
Cursor cursor2 = context.getContentResolver().query(
contactUri,
projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
new String[]{String.valueOf(id)}, null);
if(cursor2 != null) {
// Cursor valid but string below got error "android.database.CursorIndexOutOfBoundsException: Index -1 requested, with a size of 1 : )"
displayName = cursor2.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
Log.d("_TAG_", displayName);
}
}
{
//
// v. N
//
Uri myPhoneUri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI,
Uri.encode(String.valueOf(id)));
Cursor phoneCursor = context.getContentResolver().query(
myPhoneUri, null, null, null, null);
for (phoneCursor.moveToFirst(); !phoneCursor.isAfterLast(); phoneCursor.moveToNext()) {
// No steps inside!
String str = phoneCursor.getString(phoneCursor
.getColumnIndexOrThrow(ContactsContract.CommonDataKinds.Nickname.NAME));
Log.d(App.LOG_TAG, "ContactUtils.getId: " + str);
}
if(phoneCursor != null) {
phoneCursor.close();
}
}
} else {
Log.d("_TAG_", "Contact Not Found # " + number);
}
cursor.close();
}
return id;
}
"v.N-1" and "v.N" are just 2 ones from a million attempts before.
See - I got _ID, so why it doesn't work back as valid query???
Here is decision i found.
public static String getDisplayName(Context context, long id) {
String displayName = null;
// define the columns I want the query to return
final String[] projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
};
final Cursor cursor = context.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id + "" }, null);
if(cursor != null) {
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
}
return displayName;
}
It works...

How do I change the phone number to name android?

I have this method to display the contact numbers in my inbox:
public ArrayList<String> fetchInboxNumbers() {
ArrayList<String> sms = new ArrayList<String>();
Uri uriSms = Uri.parse("content://sms/inbox");
Cursor cursor = getContentResolver().query(uriSms,
new String[] { "_id", "address", "date", "body" }, null, null, null);
cursor.moveToFirst();
while (cursor.moveToNext()) {
address = cursor.getString(1); // Displays phone number
Log.d("CONTACT", address);
sms.add(address); // + " " + body
}
Log.d("NAMES IN CALLLOG", sms.get(7));
return sms;
} // END FETCHINBOX
What I'm trying to do is change String address to its contact name.
From fetchContactNumbers() and 'fetchContactNames(), how can I changeaddress` to a contact name?
Its important to understand that fetchContactNumbers and fetchContactNames() are aligned, meaning fetchContactNumbers().get(5)'s contact name is fetchContactNames().get(5)`.
In the end, fetchInboxNumbers() populates a custom adapter.
This method returns a list of all contact names:
public ArrayList<String> fetchContactNames() {
ArrayList<String> names = new ArrayList<String>();
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, null);
while (phones.moveToNext()) {
String name = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
names.add(name);
}
phones.close();
return names;
}
And this method lists all phone numbers:
public ArrayList<String> fetchContactNumbers() {
ArrayList<String> numbers = new ArrayList<String>();
Cursor phones = getContentResolver().query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, null);
while (phones.moveToNext()) {
String phoneNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
numbers.add(phoneNumber);
}
phones.close();
return numbers;
}
You can use CONTENT_FILTER_URI to get the display name, instead of getting all names and numbers separately, something like below:
public ArrayList<String> fetchInboxNumbers() {
String displayName = "";
ArrayList<String> sms = new ArrayList<String>();
Uri uriSms = Uri.parse("content://sms/inbox");
Cursor cursor = getContentResolver().query(uriSms,
new String[] { "_id", "address", "date", "body" }, null, null, null);
cursor.moveToFirst();
while (cursor.moveToNext()) {
address = cursor.getString(1); // Displays phone number
displayName = getDisplayName(address);
sms.add(displayName); // + " " + body
}
return sms;
} // END FETCHINBOX
private String getDisplayName(String phoneNumber) {
String displayName = "";
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(phoneNumber));
Cursor cursor = context.getContentResolver().query(uri, new String[] { Phone._ID, Phone.DISPLAY_NAME}, null, null, null);
if (cursor.moveToFirst()) {
displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.PhoneLookup.DISPLAY_NAME));
}
return displayName;
}
Is it a spelling mistake? a variable mistake?
private String getDisplayName(String phoneNyumber) {
Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.
CONTENT_FILTER_URI, Uri.encode(phoneNumber));
.....
}
Your argument is having phoneNyumber and you are using phoneNumber.
