Android Phone Dialer App

I'm making a Dialer and I want to search the contacts by name.
But since the Dialer accepts only numbers, how should I search for JOHN by entering the number 5-6-4-6? Are there any existing methods to do so in android?

If this number 5-6-4-6 exists in your contacst than you can use Content uri and hpone uri to lookup for this number and you can compare it with the fetched results...
You can fetch all the contacts and you get the name by comparing this number an d with the fetched numbers from the andorid conatcts api.
public void fetchContacts() {
String phoneNumber = null;
String email = null;
Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
String _ID = ContactsContract.Contacts._ID;
String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
Uri PhoneCONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String Phone_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Uri EmailCONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
String EmailCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
String DATA = ContactsContract.CommonDataKinds.Email.DATA;
StringBuffer output = new StringBuffer();
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(CONTENT_URI, null,null, null, null);
// Loop for every contact in the phone
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String contact_id = cursor.getString(cursor.getColumnIndex( _ID ));
String name = cursor.getString(cursor.getColumnIndex( DISPLAY_NAME ));
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex( HAS_PHONE_NUMBER )));
if (hasPhoneNumber > 0) {
output.append("\n First Name:" + name);
// Query and loop for every phone number of the contact
Cursor phoneCursor = contentResolver.query(PhoneCONTENT_URI, null, Phone_CONTACT_ID + " = ?", new String[] { contact_id }, null);
while (phoneCursor.moveToNext()) {
phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
output.append("\n Phone number:" + phoneNumber);
}
phoneCursor.close();
// Query and loop for every email of the contact
Cursor emailCursor = contentResolver.query(EmailCONTENT_URI, null, EmailCONTACT_ID+ " = ?", new String[] { contact_id }, null);
while (emailCursor.moveToNext()) {
email = emailCursor.getString(emailCursor.getColumnIndex(DATA));
output.append("\nEmail:" + email);
}
emailCursor.close();
}
output.append("\n");
}
outputText.setText(output);
}
}
}
this link may help you..
there are various ways to do this.

Assign each letter a numeric code as per numeric keypad with letters.
e.g.
assign 2 to a b & c
assign 3 to d e & f and so on.
Then modify your search accordingly.

Cannot get contacts from phone book android

I'm create an application to get all contacts from phone book of Android device. I synch my contacts list from Gmail to android device and I see all contacts in phone book. But when running application, cannot get any contacts from phone book.
Here is my code
MainActivity.java
public class MainActivity extends Activity {
private TextView outputText;
TextView txtViewContactsInfor;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
outputText =(TextView)findViewById(R.id.textView2);
txtViewContactsInfor = (TextView) findViewById(R.id.txtViewContactsInfor);
Import_contacts_from_address_book();
}
private void Import_contacts_from_address_book() {
// TODO Auto-generated method stub
String phoneNumber = null;
String email = null;
Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
String _ID = ContactsContract.Contacts._ID;
String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;
Uri PHONECONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String PHONECONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Uri EMAILCONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
String EMAILCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
String EMAIL = ContactsContract.CommonDataKinds.Email.DATA;
StringBuffer output = new StringBuffer();
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null, null);
System.out.println("---------------------->"+cursor.getCount());
if(cursor.getCount() >0){
int aa = cursor.getCount();
while(cursor.moveToNext()){
String contact_id = cursor.getString(cursor.getColumnIndex(_ID));
String name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME));
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(HAS_PHONE_NUMBER)));
if(hasPhoneNumber > 0 ){
output.append("\nFirst Name: "+name);
// Query and loop for every phone number of the contact
Cursor phoneCursor = contentResolver.query(PHONECONTENT_URI, null, PHONECONTACT_ID + "=?", new String[]{contact_id}, null);
while(phoneCursor.moveToNext()){
phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
output.append("\n Phone number: "+phoneNumber);
}
phoneCursor.close();
// Query and loop for every email of the contact
Cursor emailCurosr = contentResolver.query(EMAILCONTENT_URI, null, EMAILCONTACT_ID+"=?",new String[]{contact_id},null);
while(emailCurosr.moveToNext()){
email = emailCurosr.getString(emailCurosr.getColumnIndex(EMAIL));
output.append("\nEmail: "+email);
}
emailCurosr.close();
}
output.append("\n");
}
cursor.close();
}
outputText.setText(output.toString());
}
I debug in cursor.getCount and see "544 contact" was found. But
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(HAS_PHONE_NUMBER))); always zero.
I dont know why.

You might have a lot contacts without number, because contacts are stored in multiple columns.
I simplified and modified your code to count rows with and with out numbers and let it run on my phone:
private void readContacts() {
Cursor c = getContentResolver()
.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
int foundWithNumber = 0;
int foundWithOutNumber = 0;
if (c.moveToFirst()) {
int idHasNumber = c.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER);
do {
boolean hasNumber = c.getInt(idHasNumber) > 0;
if (hasNumber) {
++foundWithNumber;
} else {
++foundWithOutNumber;
}
} while (c.moveToNext());
}
Log.d(TAG, "foundWithNumber: " + foundWithNumber);
Log.d(TAG, "foundWithOutNumber: " + foundWithOutNumber);
c.close();
}
The ouput on my phone is:
MainActivity D foundWithNumber: 184
D foundWithOutNumber: 303
So, I guess, you just looked at the wrong rows. ;)

You nead add Read contact permission in Android manifest
android.permission.READ_CONTACTS

How can get data from address-book faster in Android?

I create an application to get all contact in addressbook (phone book) of Android device like Viper application.
Here is my code:
private void Import_contacts_from_address_book() {
// TODO Auto-generated method stub
String phoneNumber = null;
String email = null;

String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
Uri EMAILCONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
String EMAILCONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
String EMAIL = ContactsContract.CommonDataKinds.Email.DATA;
StringBuffer output = new StringBuffer();
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null, null);

String contact_id = cursor.getString(cursor.getColumnIndex(_ID));
String name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME));
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(HAS_PHONE_NUMBER)));
//------------------- Catch phone number, neu phone >0 thi get phone, ko thi lam chuyen khac
//if(hasPhoneNumber > 0 ){
output.append("\nFirst Name: "+name);
// Query and loop for every phone number of the contact
Cursor phoneCursor = contentResolver.query(PHONECONTENT_URI, null, PHONECONTACT_ID + "=?", new String[]{contact_id}, null);

while(emailCurosr.moveToNext()){
email = emailCurosr.getString(emailCurosr.getColumnIndex(EMAIL));
output.append("\nEmail: "+email);
}
emailCurosr.close();
//}
output.append("\n");
}
cursor.close();
}
txtViewContactsInfor.setText("Contacts: "+String.valueOf(countContact));
outputText.setText(output.toString());
}
I try to import 1000 contact and it take at least 45 second.
Is there any way to improve speed?
And when I change some information in contact of addressbook (phone book) in Android device. I using onResume() to update new information for my application but It's reload all page so It take a long time. But I see on Viper, the data updating immediately. So, is there any I can update or sync data from my device to my application like Viper application or improve speed updating, reload page ?
Any help would be much appreciated! Thanks!

Query operation is very long operation on android, because each time, when you call query, system opens database file. Opening file is expensive in android. You should call query as rarely as possible. This is my solution:
public class Contact {
public String name;
public List<String> phones;
public List<String> emails;
}
private static final Uri CONTENT_URI = ContactsContract.Contacts.CONTENT_URI;
private static final String _ID = ContactsContract.Contacts._ID;
private static final String DISPLAY_NAME = ContactsContract.Contacts.DISPLAY_NAME;
private static final Uri PHONE_CONTENT_URI = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
private static final String PHONE_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;
private static final String NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
private static final Uri EMAIL_CONTENT_URI = ContactsContract.CommonDataKinds.Email.CONTENT_URI;
private static final String EMAIL_CONTACT_ID = ContactsContract.CommonDataKinds.Email.CONTACT_ID;
private static final String EMAIL = ContactsContract.CommonDataKinds.Email.DATA;
private Collection<Contact> importContactsFromAddressBook() {
Map<String, Contact> contactMap = new HashMap<String, Contact>();
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(CONTENT_URI, null, null, null, null);
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(_ID));
String name = cursor.getString(cursor.getColumnIndex(DISPLAY_NAME));
Contact contact = new Contact();
contact.name = name;
contact.phones = new ArrayList<String>();
contact.emails = new ArrayList<String>();
contactMap.put(contactId, contact);
}
}
cursor.close();
// Query and loop for every phone number of the contact
Cursor phoneCursor = contentResolver.query(PHONE_CONTENT_URI, null, null, null, null);
while (phoneCursor.moveToNext()) {
String contactId = phoneCursor.getString(phoneCursor.getColumnIndex(PHONE_CONTACT_ID));
String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(NUMBER));
Contact contact = contactMap.get(contactId);
contact.phones.add(phoneNumber);
}
phoneCursor.close();
// Query and loop for every email of the contact
Cursor emailCursor = contentResolver.query(EMAIL_CONTENT_URI, null, EMAIL_CONTACT_ID + "=?", new String[]{contactId}, null);
while (emailCursor.moveToNext()) {
String contactId = emailCursor.getString(emailCursor.getColumnIndex(EMAIL_CONTACT_ID));
String email = emailCursor.getString(emailCursor.getColumnIndex(EMAIL));
Contact contact = contactMap.get(contactId);
contact.emails.add(email);
}
emailCursor.close();
return contactMap.values();
}

If I click on any name (list item) it stores all the contact details into an array. But I want to store only selected contacts. What should I change in my code.. please do needful help

I have modified your code. Now its working as per expectation. Vote my answer if it is helpful for you so that It will increase your ratings also
use the following code to retrieve contact from mobile.
I have tested. its working fine
public static void getContactNumbers(Context context) {
String contactNumber = null;
int contactNumberType = Phone.TYPE_MOBILE;
String nameOfContact = null;
if (ApplicationConstants.phoneContacts.size() <= 0) {
ContentResolver cr = context.getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null,
null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur
.getColumnIndex(BaseColumns._ID));
nameOfContact = cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer
.parseInt(cur.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor phones = cr
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id },
null);
while (phones.moveToNext()) {
contactNumber = phones.getString(phones
.getColumnIndex(Phone.NUMBER));
contactNumberType = phones.getInt(phones
.getColumnIndex(Phone.TYPE));
Log.i(TAG, "...Contact Name ...." + nameOfContact
+ "...contact Number..." + contactNumber);
}
phones.close();
}
}
}// end of contact name cursor
cur.close();
}
}

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)
String Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}

public void readContacts()
{
int i=0;
Cursor cursor=getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,null,null,null);
count=cursor.getCount();
names=new String[count];
phno=new String[count];
while(cursor.moveToNext())
{
names[i]=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)) ;
phno[i]=cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
i++;
}

Read all contacts' phone numbers in android

I'm using this code to retrieve all contact names and phone numbers:
String[] projection = new String[]
{
People.NAME,
People.NUMBER
};
Cursor c = ctx.getContentResolver().query(People.CONTENT_URI, projection, null, null, People.NAME + " ASC");
c.moveToFirst();
int nameCol = c.getColumnIndex(People.NAME);
int numCol = c.getColumnIndex(People.NUMBER);
int nContacts = c.getCount();
do
{
// Do something
} while(c.moveToNext());
However, this will only return the primary number for each contact, but I want to get the secondary numbers as well. How can i do this?

Following code shows an easy way to read all phone numbers and names:
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));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
NOTE: getContentResolver is a method from the Activity context.

You can read all of the telephone numbers associated with a contact in the following manner:
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, personId);
Uri phonesUri = Uri.withAppendedPath(personUri, People.Phones.CONTENT_DIRECTORY);
String[] proj = new String[] {Phones._ID, Phones.TYPE, Phones.NUMBER, Phones.LABEL}
Cursor cursor = contentResolver.query(phonesUri, proj, null, null, null);
Please note that this example (like yours) uses the deprecated contacts API. From eclair onwards this has been replaced with the ContactsContract API.

This code shows how to get all phone numbers for each contact.
ContentResolver cr = getActivity().getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
int phoneType = pCur.getInt(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.TYPE));
String phoneNumber = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
switch (phoneType) {
case Phone.TYPE_MOBILE:
Log.e(name + "(mobile number)", phoneNumber);
break;
case Phone.TYPE_HOME:
Log.e(name + "(home number)", phoneNumber);
break;
case Phone.TYPE_WORK:
Log.e(name + "(work number)", phoneNumber);
break;
case Phone.TYPE_OTHER:
Log.e(name + "(other number)", phoneNumber);
break;
default:
break;
}
}
pCur.close();
}
}
}

In case it helps, I've got an example that uses the ContactsContract API to first find a contact by name, then it iterates through the details looking for specific number types:
How to use ContactsContract to retrieve phone numbers and email addresses

You can get all phone contacts using this:
Cursor c = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
new String[] { ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.RawContacts.ACCOUNT_TYPE },
ContactsContract.RawContacts.ACCOUNT_TYPE + " <> 'google' ",
null, null);
check complete example HERE...........

String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0)
{
System.out.println("name : " + name + ", ID : " + id);
// get the <span id="IL_AD4" class="IL_AD">phone
// number</span>
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[] { id }, null);
while (pCur.moveToNext())
{
String phone = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
}
pCur.close();

Accepted answer working but not given unique numbers.
See this code, it return unique numbers.
public static void readContacts(Context context) {
if (context == null)
return;
ContentResolver contentResolver = context.getContentResolver();
if (contentResolver == null)
return;
String[] fieldListProjection = {
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER,
ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER,
ContactsContract.Contacts.HAS_PHONE_NUMBER
};
Cursor phones = contentResolver
.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI
, fieldListProjection, null, null, null);
HashSet<String> normalizedNumbersAlreadyFound = new HashSet<>();
if (phones != null && phones.getCount() > 0) {
while (phones.moveToNext()) {
String normalizedNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NORMALIZED_NUMBER));
if (Integer.parseInt(phones.getString(phones.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
if (normalizedNumbersAlreadyFound.add(normalizedNumber)) {
String id = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID));
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
Log.d("test", " Print all values");
}
}
}
phones.close();
}
}

In the same way just get their other numbers using the other "People" references
People.TYPE_HOME
People.TYPE_MOBILE
People.TYPE_OTHER
People.TYPE_WORK

This one finally gave me the answer I was looking for. It lets you retrieve all the names and phone numbers of the contacts on the phone.
package com.test;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
public class TestContacts extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, null);
if (cur != null && cur.getCount() > 0) {
while (cur.moveToNext()) {
if (Integer.parseInt.equals(cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.HAS_PHONE_NUMBER)))) {
String id = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(
ContactsContract.Contacts.DISPLAY_NAME));
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
int i = 0;
int pCount = pCur.getCount();
String[] phoneNum = new String[pCount];
String[] phoneType = new String[pCount];
while (pCur != null && pCur.moveToNext()) {
phoneNum[i] = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneType[i] = pCur.getString(pCur.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.TYPE));
i++;
}
}
}
}
}
}

I fixed my need belove
manifest permissions
<uses-permission android:name="android.permission.READ_CONTACTS" />
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<!-- Read Contacts from phone -->
<uses-permission android:name="android.permission.read_contacts" />
<uses-permission android:name="android.permission.read_phone_state" />
<uses-permission android:name="android.permission.READ_CALL_LOG" />
Note: After giving permissions at manifest some mobile phones can deny if so you need to go Settings--> Applications--> find your application click on it and
turn On the permissions needed
btn_readallcontacks.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
List<User> userList = new ArrayList<User>();
while (phones.moveToNext()) {
User user = new User();
user.setNamee(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)));
user.setPhone(phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)));
userList.add(user);
Log.d(TAG, "Name : " + user.getNamee().toString());
Log.d(TAG, "Phone : " + user.getPhone().toString());
}
phones.close();
}
});

You can get all the contact all those which have no number and all those which have no name from this piece of code
public void readContacts() {
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI,
null, null, null, ContactsContract.RawContacts.DISPLAY_NAME_PRIMARY + " ASC");
ContactCount = cur.getCount();
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
String phone = null;
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {

One thing can be done you have to give the permission in the manifest for contact READ and WRITE
After that you can create the model class for the list which can be use to add all the contact here is the model class
public class PhoneModelClass {
private String number;
private String name;
private String id;
private String rawId;
public PhoneModelClass(String number, String name, String id, String rawId) {
this.number = number;
this.name = name;
this.id = id;
this.rawId = rawId;
}
public PhoneModelClass(String number, String name, String id) {
this.number = number;
this.name = name;
this.id = id;
}
public String getRawId() {
return rawId;
}
public void setRawId(String rawId) {
this.rawId = rawId;
}
public String getNumber() {
return number;
}
public void setNumber(String number) {
this.number = number;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
}
Enjoy :)

Load contacts in background using CursorLoader:
CursorLoader cursor = new CursorLoader(this, ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
Cursor managedCursor = cursor.loadInBackground();
int number = managedCursor.getColumnIndex(ContactsContract.Contacts.Data.DATA1);
int name = managedCursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int index = 0;
while (managedCursor.moveToNext()) {
String phNumber = managedCursor.getString(number);
String phName = managedCursor.getString(name);
}

Here's how to use ContentsContract API to fetch your contacts in your Phone Book.
You'll need to add these permissions in your AndroidManifest.xml
<uses-permission android:name="android.permission.WRITE_CONTACTS" />
<uses-permission android:name="android.permission.READ_CONTACTS" />
Then, you can run this method to loop through all your contacts.
Here's an example to query fields like Name and Phone Number, you can configure yourself to use CommonDataKinds, it query other fields in your Contact.
https://developer.android.com/reference/android/provider/ContactsContract.CommonDataKinds
private fun readContactsOnDevice() {
val context = requireContext()
if (ContextCompat.checkSelfPermission(
context, Manifest.permission.WRITE_CONTACTS
) != PackageManager.PERMISSION_GRANTED &&
ContextCompat.checkSelfPermission(
context, Manifest.permission.READ_CONTACTS
) != PackageManager.PERMISSION_GRANTED
) {
requestPermissions(
arrayOf(Manifest.permission.READ_CONTACTS, Manifest.permission.WRITE_CONTACTS), 1
)
return
}
val contentResolver = context.contentResolver
val contacts = contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null, null, null, null
)
while (contacts?.moveToNext() == true) {
val name = contacts.getString(
contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME)
)
val phoneNumber = contacts.getString(
contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)
)
Timber.i("Name: $name, Phone Number: $phoneNumber")
}
}

Code to get contact name (Ascending order) and number
For more reference: show contact in listview
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME+" ASC");
while (phones.moveToNext())
