Realm.io - How to use wildcard% LIKE% for request

Question

I am trying to do:

mRealm .where(Contact.class) .equalTo(Contact.NAME, text, Case.INSENSITIVE) .findAllSortedAsync(Contact.NAME, Sort.ASCENDING); 

Result: The expected result is not fulfilled.

 mRealm .where(Contact.class) .contains(Contact.NAME, text, Case.INSENSITIVE) .findAllSortedAsync(Contact.NAME, Sort.ASCENDING); 

Result: The expected result is not fulfilled.

Expected Result:

 mRealm .where(Contact.class) .like(Contact.NAME, text, Case.INSENSITIVE) .findAllSortedAsync(Contact.NAME, Sort.ASCENDING); 

Answer 1

NEW RESPONSE:

Realm 2.3.0 +:

 public RealmQuery<E> like(String fieldName, String value, Case casing) 

The condition that the field value matches the specified substring, with wildcards:

• '*' matches [0, n] unicode characters

• '?' matches one unicode char.

Options:

• fieldName - field to compare.

• value is a wildcard.

• casing - how to handle the case. Setting this parameter to Case.INSENSITIVE only works for Latin-1 characters.

Returns: request object.

Throws: IllegalArgumentException - if one or more arguments do not match the type of the class or field.

OLD RESPONSE:

 mRealm .where(Contact.class) .contains(Contact.NAME, text, Case.INSENSITIVE) .findAllSortedAsync(Contact.NAME, Sort.ASCENDING); 

This should work, but you will get a callback from the added RealmChangeListener when the actual asynchronous request completes.

A RealmRecyclerViewAdapter does this automatically from https://github.com/realm/realm-android-adapters .

Answer 2

 mRealm .where(Contact.class) .like(Contact.NAME, text, Case.INSENSITIVE) .findAllSortedAsync(Contact.NAME, Sort.ASCENDING);
