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 ContactsContract?

Answer 1

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()) ;
    }

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.

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;
}

Try this also get all contacts.

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