未能一对一读取和删除记录存储 [英] Failed to Read and delete recordstore one by one

问题描述

大家好....

请帮帮我.

我正在编写一些代码来从rms读取数据存储，并将其存储到j2me中的List(lstInbox.append(.....)).当我从列表中读取1行索引时，我的窗体(frmInbox)始终以rms显示所有数据(如果可以读取所有数据，则可以).而且，我无法将其一一删除(删除所有记录都可以).

有人可以帮我吗?

这是我的一些代码:

Can anyone help me, please?

Here my some code:

public void bacaPesanMasuk() {
        status = 1;
        byte[] bPesan = null;
        frmBaca.deleteAll();

            re = rs.enumerateRecords(null, this, true);
            while (re.hasNextElement()) {
                int i = re.nextRecordId();
                bPesan = rs.getRecord(i);
                ByteArrayInputStream bais = new ByteArrayInputStream(bPesan);
                DataInputStream dis = new DataInputStream(bais);
                try {
                    String noTelp = dis.readUTF();
                    String pesan = dis.readUTF();

推荐答案

使用枚举器时不应删除项目.使用枚举器标识列表中要删除的项目，并将其添加到临时列表中.然后从原始列表中删除临时列表中的项目.

You should not delete items when using an enumerator. Use the enumerator to identify the items in the list to be deleted and add them to a temporary list. Then delete the items from the original list that are in the temporary list.
