安装WhatsApp时获取联系人会产生重复的条目

Question

我正在从android获取联系人并将其存储在数据库中。在模拟器上对其进行了测试，并且可以正常工作。但是，当我在手机上测试该应用程序时，我得到了使用Whatsapp的联系人的重复条目。下面是代码片段。

class LoadContactAsync extends AsyncTask<Void, Void, String> {

    @Override
    protected String doInBackground(Void... params) {
        Cursor people = getContentResolver()
                .query(ContactsContract.Contacts.CONTENT_URI, null, null, null,
                        "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME
                                + ") ASC");
        while (people.moveToNext()) {
            final String contactId = people.getString(people
                    .getColumnIndex(ContactsContract.Contacts._ID));
            final String contactName = people
                    .getString(people
                            .getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            final String image_uri = people
                    .getString(people
                            .getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
            final String hasPhone = people
                    .getString(people
                            .getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
            if ((Integer.parseInt(hasPhone) > 0)) {
                Cursor phones = getContentResolver().query(
                        ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,
                        ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = " + contactId, null,
                        "UPPER(" + ContactsContract.Contacts.DISPLAY_NAME + ") ASC");
                while (phones.moveToNext()) {
                    final String phoneNumber = phones
                            .getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                    db.addContact(new Contact(contactName, phoneNumber, image_uri));
                }
                phones.close();
            }
        }
        people.close();
        return null;
    }

    @Override
    protected void onPostExecute(String s) {
        pd.dismiss();
        showToast("Contacts Added Successfully");
        db.close();
    }

    @Override
    protected void onPreExecute() {
        pd = ProgressDialog.show(MainActivity.this, "Please Wait...",
                "Fetching One Time Contacts", true, false);
    }
}

如果您不想使用数据库来避免重复输入，请使用以下代码

    private HashMap<String, ContactModel> getContactsList() {
    String[] projection = new String[]{ContactsContract.Contacts._ID, ContactsContract.Data.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.PHOTO_URI};
    Cursor phones = getActivity().getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, projection, null, null,
            ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC");


    String lastPhoneName = " ";
    if (phones.getCount() > 0) {
        while (phones.moveToNext()) {
            String name = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
            String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
            String contactId = phones.getString(phones.getColumnIndex(ContactsContract.Contacts._ID));
            String photoUri = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI));
            if (!name.equalsIgnoreCase(lastPhoneName)) {
                lastPhoneName = name;
                contactDetail.put(contactId, new ContactModel(contactId, name, phoneNumber, photoUri));
                Log.d("getContactsList", name + "---" + phoneNumber + " -- " + contactId + " -- " + photoUri);
            }
        }
    }
    phones.close();

    return contactDetail;
}
