android - 获取的联系号码显示重复号码（Whatsapp 和双人号码）

问题描述

我正在创建一个应用程序，它将在警报对话框中将联系人的电话号码显示为列表。我的问题是它会显示重复的号码，其中联系人在电话联系人应用程序中没有重复的号码。（我的假设是它是从 whatsapp 获取的号码，双人号码等）

这是我在 onActivityResult 中获取代码的联系人。

  if (resultCode == RESULT_OK) {
                switch (reqCode) {
                    case REQUEST_CODE:
                        final TextView phoneInput = (TextView) findViewById(R.id.contact);
                        Cursor cursor = null;
                        String phoneNumber = "";
                        List<String> allNumbers = new ArrayList<String>();
                        int phoneIdx = 0;
                        try {
                            Uri result = data.getData();
                            String id = result.getLastPathSegment();
                            cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=?", new String[] { id }, null);
                            phoneIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
                            if (cursor.moveToFirst()) {
                                while (cursor.isAfterLast() == false) {
                                    phoneNumber = cursor.getString(phoneIdx);
                                    allNumbers.add(phoneNumber);
                                    cursor.moveToNext();
                                }
                            } else {
                                //no results actions
                            }
                        } catch (Exception e) {
                            //error actions
                        } finally {
                            if (cursor != null) {
                                cursor.close();
                            }

                            final CharSequence[] items = allNumbers.toArray(new String[allNumbers.size()]);
                            AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                            builder.setTitle("Choose a number");
                            builder.setItems(items, new DialogInterface.OnClickListener() {
                                public void onClick(DialogInterface dialog, int item) {
                                    String selectedNumber = items[item].toString();
                                    selectedNumber = selectedNumber.replace("-", "");
                                    phoneInput.setText(selectedNumber);
                                }
                            });
                            AlertDialog alert = builder.create();
                            if(allNumbers.size() > 1) {

                            }

                            if (phoneNumber.length() == 0) {
                                //no numbers found actions
                            }

Map<String, String> filteredList = new HashMap<>();
        if (resultCode == RESULT_OK) {
            switch (reqCode) {
