Answer 1

Try this way..

Uri uri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
            String[] projection    = new String[] {ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME,
                    ContactsContract.CommonDataKinds.Phone.NUMBER};

            Cursor cursor = getContentResolver().query(uri, projection, null, null, null);

            int idxName = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
            int idxNumber = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

            if(cursor.moveToFirst()) {
                do {
                    contactname   = cursor.getString(idxName);
                    contactNumber = cursor.getString(idxNumber);

                    if (contactname.equals("YOUR CONTACT NAME")){
                        Log.d(LOG_TAG,"Contact Name -> "+ contactname +" Contact Number -> "+ contactNumber);
                    }
                } while (cursor.moveToNext());
            }
            cursor.close();
