Java – content resolver and “in” statement in “where” statement

I'm trying to get the cursor of the contact list based on therir ID I'm not sure how to use an "in" statement with an array of parameters I have something wrong right now

public Cursor GetContacts(String[] ids)
{
    ContentResolver cr = getContentResolver();

    try
    {
        Uri uri = ContactsContract.Contacts.CONTENT_URI;

        String[] projection = new String[] {
                ContactsContract.Contacts._ID,ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.Contacts.HAS_PHONE_NUMBER
        };

        String where = ContactsContract.Contacts._ID + " IN ?";

        String[] selectionArgs = ids;

        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME;

        return cr.query(uri,projection,where,selectionArgs,sortOrder);
    }
    catch (Exception ex)
    {
    String message = ex.getMessage();
    Log.e("mine","Error: " + message,ex);

    return null;
    }

Error: approaching '?': Syntax error (code 1):, compile time: Select_ id,display_ name,has_ phone_ number FROM view_ contacts WHERE((1))AND((_id IN？)) ORDER BY display_ name

Solution

I didn't test this, but I think you need to compress your ID into a comma separated string to insert it into your query

public Cursor GetContacts(String[] ids)
{
    ContentResolver cr = getContentResolver();

    try
    {
        Uri uri = ContactsContract.Contacts.CONTENT_URI;

        String[] projection = new String[] {
                ContactsContract.Contacts._ID,ContactsContract.Contacts.HAS_PHONE_NUMBER
        };

        String where = ContactsContract.Contacts._ID + " IN (?)";

        String[] selectionArgs = {StringUtils.join(ids,",")};

        String sortOrder = ContactsContract.Contacts.DISPLAY_NAME;

        return cr.query(uri,ex);

    return null;
    }
