Realm是否支持Android上的模糊查询

Question

我的团队决定使用领域作为数据库，但我有一个问题要问， Realm是否支持模糊查询，如SQLite使用关键字＆＃39; like＆＃39;或者＆＃39;％＆＃39;有时候我们需要使用模糊查询

Answer 1

LIKE query is supported since 2.3.0.

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

Condition that the value of field matches with the specified substring, with wildcards:
    '*' matches [0, n] unicode chars
    '?' matches a single unicode char.

Parameters:
    fieldName - the field to compare.
    value - the wildcard string.
    casing - how to handle casing. Setting this to Case.INSENSITIVE only works for Latin-1 characters.

示例：

realm.where(Person.class).like("name", "*").findAll();
realm.where(Person.class).like("name", "?ohn*", Case.SENSITIVE).findAll();
