Android get all contacts telephone number in ArrayList

Question

I am trying to save all contacts telephone numbers in an ArrayList but I cant find a way how. Is there a way to get them instead of picking them one by one with ContactsCont

Answer 1

This code will work much faster than code in the answer, because you don't make additional query for each contact.

private static final String CONTACT_ID = ContactsContract.Contacts._ID;
private static final String HAS_PHONE_NUMBER = ContactsContract.Contacts.HAS_PHONE_NUMBER;

private static final String PHONE_NUMBER = ContactsContract.CommonDataKinds.Phone.NUMBER;
private static final String PHONE_CONTACT_ID = ContactsContract.CommonDataKinds.Phone.CONTACT_ID;

public static ArrayList<String> getAll(Context context) {
    ContentResolver cr = context.getContentResolver();

    Cursor pCur = cr.query(
            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
            new String[]{PHONE_NUMBER, PHONE_CONTACT_ID},
            null,
            null,
            null
    );
    if(pCur != null){
        if(pCur.getCount() > 0) {
            HashMap<Integer, ArrayList<String>> phones = new HashMap<>();
            while (pCur.moveToNext()) {
                Integer contactId = pCur.getInt(pCur.getColumnIndex(PHONE_CONTACT_ID));
                ArrayList<String> curPhones = new ArrayList<>();
                if (phones.containsKey(contactId)) {
                    curPhones = phones.get(contactId);
                }
                curPhones.add(pCur.getString(pCur.getColumnIndex(PHONE_NUMBER)));
                phones.put(contactId, curPhones);
            }
            Cursor cur = cr.query(
                    ContactsContract.Contacts.CONTENT_URI,
                    new String[]{CONTACT_ID, HAS_PHONE_NUMBER},
                    HAS_PHONE_NUMBER + " > 0",
                    null,null);
            if (cur != null) {
                if (cur.getCount() > 0) {
                    ArrayList<String> contacts = new ArrayList<>();
                    while (cur.moveToNext()) {
                        int id = cur.getInt(cur.getColumnIndex(CONTACT_ID));
                        if(phones.containsKey(id)) {
                            contacts.addAll(phones.get(id));
                        }
                    }
                    return contacts;
                }
                cur.close();
            }
        }
        pCur.close();
    }
    return null;
}

Answer 2

This method is optimized as well as fetch only distinct contacts

@RequiresApi(api = Build.VERSION_CODES.N)
private List<ModelContacts> getContacts() {

    ArrayList<ModelContacts> list = new ArrayList<>();
    Cursor cursor = this.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);

    cursor.moveToFirst();

    while (cursor.moveToNext()) {

        list.add(new ModelContacts(cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME))
                , cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER))));

    }
    cursor.close();

    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {

        List<ModelContacts> distinctList = list.stream().filter(distinctByKey(c -> c.getName()))
                .collect(Collectors.toList());
        
        return distinctList;
    }
    else {
       
        return list;
    }
}

@RequiresApi(api = Build.VERSION_CODES.N)
public static <T> Predicate<T> distinctByKey (final Function<? super T, Object> keyExtractor)
{
    Map<Object, Boolean> map = new ConcurrentHashMap<>();
    return t -> map.putIfAbsent(keyExtractor.apply(t), Boolean.TRUE) == null;
}

Answer 3

in kotlin try this to get all contacts

fun getContacts(ctx: Context): List<ContactModel>? {
    val list: MutableList<ContactModel> = ArrayList()
    val contentResolver = ctx.contentResolver
    val cursor: Cursor? =
        contentResolver.query(
            ContactsContract.Contacts.CONTENT_URI, null,
            null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC"
        )
    if (cursor!!.count > 0) {
        while (cursor.moveToNext()) {
            val id =
                cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID))
            if (cursor.getInt(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)) > 0) {
                val cursorInfo: Cursor? = contentResolver.query(
                    ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                    null,
                    ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                    arrayOf(id),
                    null
                )
                val inputStream: InputStream? =
                    ContactsContract.Contacts.openContactPhotoInputStream(
                        ctx.contentResolver,
                        ContentUris.withAppendedId(
                            ContactsContract.Contacts.CONTENT_URI,
                            id.toLong()
                        )
                    )
                val person: Uri =
                    ContentUris.withAppendedId(
                        ContactsContract.Contacts.CONTENT_URI,
                        id.toLong()
                    )
                val pURI: Uri = Uri.withAppendedPath(
                    person,
                    ContactsContract.Contacts.Photo.CONTENT_DIRECTORY
                )
                var photo: Bitmap? = null
                if (inputStream != null) {
                    photo = BitmapFactory.decodeStream(inputStream)
                }
                while (cursorInfo!!.moveToNext()) {
                    val info = ContactModel()
                    info.setId(id)
                    info.setName(cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)))

                    info.setMobileNumber(
                        cursorInfo.getString(
                            cursorInfo.getColumnIndex(
                                ContactsContract.CommonDataKinds.Phone.NUMBER
                            )
                        )
                    )

                    photo?.let { info.setPhoto(it) }
                    info.setPhotoURI(pURI)
                    list.add(info)
                }
                cursorInfo.close()
            }
        }
        cursor.close()
    }
    return list
}

Need to create one data class for this

class ContactModel {
@SerializedName("id")
private var id: String = ""

@SerializedName("name")
private var name: String? = ""

@SerializedName("mobileNumber")
private var mobileNumber: String? = ""

@SerializedName("photo")
private var photo: Bitmap? = null

@SerializedName("photoURI")
private var photoURI: Uri? = null


fun getId(): String {
    return id
}

fun setId(id: String) {
    this.id = id
}

fun getName(): String? {
    return name
}

fun setName(name: String) {
    this.name = name
}

fun getMobileNumber(): String? {
    return mobileNumber
}

fun setMobileNumber(mobileNumber: String) {
    this.mobileNumber = mobileNumber
}

fun getPhoto(): Bitmap? {
    return photo
}

fun setPhoto(photo: Bitmap) {
    this.photo = photo
}

fun getPhotoURI(): Uri? {
    return photoURI
}

fun setPhotoURI(photoURI: Uri) {
    this.photoURI = photoURI
}


override fun toString(): String {
    return "ContactModel(id='$id', name=$name, mobileNumber=$mobileNumber, photo=$photo, photoURI=$photoURI)"
}

}

Answer 4

Try this also get all contacts.

Cursor cursor = context.getContentResolver().query(Phone.CONTENT_URI, null , null , null,
                        "upper("+Phone.DISPLAY_NAME + ") ASC");

Answer 5

Try this:

Cursor managedCursor = getContentResolver()
    .query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
     new String[] {Phone._ID, Phone.DISPLAY_NAME, Phone.NUMBER}, null, null,  Phone.DISPLAY_NAME + " ASC");

And by traversing through the cursor, you can store all this data in any data structure of your choice.

Answer 6

ContentResolver cr = mContext.getContentResolver(); //Activity/Application android.content.Context
    Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
    if(cursor.moveToFirst())
    {
        ArrayList<String> alContacts = new ArrayList<String>();
        do
        {
            String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));

            if(Integer.parseInt(cursor.getString(cursor.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()) 
                {
                    String contactNumber = pCur.getString(pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    alContacts.add(contactNumber);
                    break;
                }
                pCur.close();
            }

        } while (cursor.moveToNext()) ;
    }
