【Android】解决GreenDao模糊查询数据为0

问题复现

模糊查询，我们在GreenDao是使用like
我们查询学生名称包含“一”的，代码示例：

 public List queryListByMessage(String name){
    DaoSession daoSession = ((Application) getApplication()).getDaoSession();
        QueryBuilder qb = daoSession.queryBuilder(Student.class);
        QueryBuilder studentQueryBuilder = qb.where(StudentDao.Properties.Name.like("一")).orderAsc(StudentDao.Properties.Name);
        List studentList = studentQueryBuilder.list();
        return list;
    }

这样查询出来的数据是0

解决办法

在like方法中，将字符串前后加上%符号，代码示例：

 public List queryListByMessage(String name){
    DaoSession daoSession = ((Application) getApplication()).getDaoSession();
        QueryBuilder qb = daoSession.queryBuilder(Student.class);
        QueryBuilder studentQueryBuilder = qb.where(StudentDao.Properties.Name.like("%"+"一"+"%")).orderAsc(StudentDao.Properties.Name);
        List studentList = studentQueryBuilder.list();
        return list;
    }
