Error in looking up a contact Android

问题

I am getting an error when I want to access the a specific contact.

java.lang.IllegalArgumentException: Invalid column contact_id

Here is the sample code:

String number = "0877777777";
                Uri uri = Uri.withAppendedPath(ContactsContract.PhoneLookup.CONTENT_FILTER_URI, Uri.encode(number));
                String[] projection = new String[]{ ContactsContract.PhoneLookup.CONTACT_ID };

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

                // if other contacts have that phone as well, we simply take the first contact found.
                if (cur != null && cur.moveToNext()) {
                    Long id = cur.getLong(0);

                    Intent intent = new Intent(Intent.ACTION_VIEW);
                    Uri contactUri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, String.valueOf(id));
                    intent.setData(contactUri);
                    startActivity(intent);

                    cur.close();
                }

The error is in the projection but I am not sure how to fix it. The number is saved on the phone under test. Any advice on solving the problem would be much appreciated.

回答1:

Just change ContactsContract.PhoneLookup.CONTACT_ID to ContactsContract.PhoneLookup._ID.

The _ID in PhoneLookup simply mean the CONTACT_ID

See here: https://developer.android.com/reference/android/provider/ContactsContract.PhoneLookup.html

回答2:

Use ContactsContract.CommonDataKinds.Phone.CONTENT_URI instead of ContactsContract.PhoneLookup.CONTACT_ID
