Eu estou tentando filtrar os resultados de um cursor retornado da minha classe manipulador de banco de dados através do uso de 'setFilterQueryProvider' na classe de adaptador de cursor simples. No momento estou recebendo vários erros no seguinte método:

Erros atuais:

Erro 1:

The method FilterQueryProvider() is undefined for the type ViewAppointments.

Erro 2:

Syntax error, insert ";" to complete Statement.

Erro 3:

Illegal modifier for the variable runQuery; only final is permitted

Erro 4:

Syntax error on token ")", ; expected

Erro 5:

Void methods cannot return a value.

Erro 6:

Syntax error on token ")", delete this token.

Os erros acima são anotados no seguinte código:

DBHandlerApp changedAppoint = new DBHandlerApp (this, null, null);

             //ERROR 1 on 'FilterQueryProvider' and ERROR 2 on end ')'.
     cursorAdapter.setFilterQueryProvider(FilterQueryProvider()

            {

            //ERROR 3 on 'runQuery'. Error 4 on end ')'.
        public Cursor runQuery(CharSequence constraint)
        {
                //ERROR 5.
            return changedAppoint.getChanges(constraint.toString());

        }
        ERROR 6 on end ')'
    });

Aqui está a aula completa. Atualmente tenho este método problemático no meu método 'onCreate' da classe. O fato de 'ERRO 5' está reclamando sobre o tipo de retorno me leva a acreditar que estar em 'OnCreate' é o lugar errado, obviamente, é nulo. Colocando-o mais onde no código produz outros erros de colchetes.

Espero que alguém possa ver onde meu erro de layout está errado.
