How can I get all the names of the contacts in my Android and put them into array of strings?
This question is related to
android
Get contacts info , photo contacts , photo uri and convert to Class model
1). Sample for Class model :
public class ContactModel {
public String id;
public String name;
public String mobileNumber;
public Bitmap photo;
public Uri photoURI;
}
2). get Contacts and convert to Model
public List<ContactModel> getContacts(Context ctx) {
List<ContactModel> list = new ArrayList<>();
ContentResolver contentResolver = ctx.getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
if (cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
Cursor cursorInfo = contentResolver.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id}, null);
InputStream inputStream = ContactsContract.Contacts.openContactPhotoInputStream(ctx.getContentResolver(),
ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id)));
Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, new Long(id));
Uri pURI = Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
Bitmap photo = null;
if (inputStream != null) {
photo = BitmapFactory.decodeStream(inputStream);
}
while (cursorInfo.moveToNext()) {
ContactModel info = new ContactModel();
info.id = id;
info.name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
info.mobileNumber = cursorInfo.getString(cursorInfo.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
info.photo = photo;
info.photoURI= pURI;
list.add(info);
}
cursorInfo.close();
}
}
cursor.close();
}
return list;
}
Get all contacts in less than a second and without any load in your activity. Follow my steps works like a charm.
ArrayList<Contact> contactList = new ArrayList<>();
private static final String[] PROJECTION = new String[]{
ContactsContract.CommonDataKinds.Phone.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone.NUMBER
};
private void getContactList() {
ContentResolver cr = getContentResolver();
Cursor cursor = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, PROJECTION, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
if (cursor != null) {
HashSet<String> mobileNoSet = new HashSet<String>();
try {
final int nameIndex = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int numberIndex = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
String name, number;
while (cursor.moveToNext()) {
name = cursor.getString(nameIndex);
number = cursor.getString(numberIndex);
number = number.replace(" ", "");
if (!mobileNoSet.contains(number)) {
contactList.add(new Contact(name, number));
mobileNoSet.add(number);
Log.d("hvy", "onCreaterrView Phone Number: name = " + name
+ " No = " + number);
}
}
} finally {
cursor.close();
}
}
}
Contacts
public class Contact {
public String name;
public String phoneNumber;
public Contact() {
}
public Contact(String name, String phoneNumber ) {
this.name = name;
this.phoneNumber = phoneNumber;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPhoneNumber() {
return phoneNumber;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
}

This is the Method to get contact list Name and Number
private void getAllContacts() {
ContentResolver contentResolver = getContentResolver();
Cursor cursor = contentResolver.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");
if (cursor.getCount() > 0) {
while (cursor.moveToNext()) {
int hasPhoneNumber = Integer.parseInt(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)));
if (hasPhoneNumber > 0) {
String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
Cursor phoneCursor = contentResolver.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?", new String[]{id},
null);
if (phoneCursor != null) {
if (phoneCursor.moveToNext()) {
String phoneNumber = phoneCursor.getString(phoneCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
//At here You can add phoneNUmber and Name to you listView ,ModelClass,Recyclerview
phoneCursor.close();
}
}
}
}
}
}
Improving on the answer of @Adiii - It Will Cleanup The Phone Number and Remove All Duplicates
Declare a Global Variable
// Hash Maps
Map<String, String> namePhoneMap = new HashMap<String, String>();
Then Use The Function Below
private void getPhoneNumbers() {
Cursor phones = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
// Loop Through All The Numbers
while (phones.moveToNext()) {
String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Cleanup the phone number
phoneNumber = phoneNumber.replaceAll("[()\\s-]+", "");
// Enter Into Hash Map
namePhoneMap.put(phoneNumber, name);
}
// Get The Contents of Hash Map in Log
for (Map.Entry<String, String> entry : namePhoneMap.entrySet()) {
String key = entry.getKey();
Log.d(TAG, "Phone :" + key);
String value = entry.getValue();
Log.d(TAG, "Name :" + value);
}
phones.close();
}
Remember in the above example the key is phone number and value is a name so read your contents like 998xxxxx282->Mahatma Gandhi instead of Mahatma Gandhi->998xxxxx282
public class MyActivity extends Activity
implements LoaderManager.LoaderCallbacks<Cursor> {
private static final int CONTACTS_LOADER_ID = 1;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
// Prepare the loader. Either re-connect with an existing one,
// or start a new one.
getLoaderManager().initLoader(CONTACTS_LOADER_ID,
null,
this);
}
@Override
public Loader<Cursor> onCreateLoader(int id, Bundle args) {
// This is called when a new Loader needs to be created.
if (id == CONTACTS_LOADER_ID) {
return contactsLoader();
}
return null;
}
@Override
public void onLoadFinished(Loader<Cursor> loader, Cursor cursor) {
//The framework will take care of closing the
// old cursor once we return.
List<String> contacts = contactsFromCursor(cursor);
}
@Override
public void onLoaderReset(Loader<Cursor> loader) {
// This is called when the last Cursor provided to onLoadFinished()
// above is about to be closed. We need to make sure we are no
// longer using it.
}
private Loader<Cursor> contactsLoader() {
Uri contactsUri = ContactsContract.Contacts.CONTENT_URI; // The content URI of the phone contacts
String[] projection = { // The columns to return for each row
ContactsContract.Contacts.DISPLAY_NAME
} ;
String selection = null; //Selection criteria
String[] selectionArgs = {}; //Selection criteria
String sortOrder = null; //The sort order for the returned rows
return new CursorLoader(
getApplicationContext(),
contactsUri,
projection,
selection,
selectionArgs,
sortOrder);
}
private List<String> contactsFromCursor(Cursor cursor) {
List<String> contacts = new ArrayList<String>();
if (cursor.getCount() > 0) {
cursor.moveToFirst();
do {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
contacts.add(name);
} while (cursor.moveToNext());
}
return contacts;
}
}
and do not forget
<uses-permission android:name="android.permission.READ_CONTACTS" />
Cursor contacts = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
String aNameFromContacts[] = new String[contacts.getCount()];
String aNumberFromContacts[] = new String[contacts.getCount()];
int i = 0;
int nameFieldColumnIndex = contacts.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
int numberFieldColumnIndex = contacts.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
while(contacts.moveToNext()) {
String contactName = contacts.getString(nameFieldColumnIndex);
aNameFromContacts[i] = contactName ;
String number = contacts.getString(numberFieldColumnIndex);
aNumberFromContacts[i] = number ;
i++;
}
contacts.close();
The result will be aNameFromContacts array full of contacts. Also ensure that you have added
<uses-permission android:name="android.permission.READ_CONTACTS" />
in main.xml
