我已经使用这种方法将 xml 文件序列化到 SD 卡

http://www.anddev.org/write_a_simple_xml_file_in_the_sd_card_using_xmlserializer-t8350.html

它工作正常,但在某些时候它停止工作

问题与大小有关,我的意思是 XML 文件大小

因为如果我使用较小的文件,它可以正常工作

也许如果我将此方法与 BufferedOutputStream 而不是 FileOutputStream 一起使用会起作用...但我不知道如何调整代码以使用缓冲区

Ant 那是我的问题,如何在这段代码中添加缓冲区。

这是我得到的输出日志:

根据xmlpull 文档setOutput 函数采用 Writer 类的实例和用于编码的字符串作为参数。因此,您也可以使用 BufferedWriter,而不是使用 BufferedOutputStream。尝试将第 47 行和第 49 行替换为以下内容:

47  BufferedWriter fileos = null;
49  fileos = new BufferedWriter(new FileWriter(newxmlfile));

只需替换行

FileOutputStream fileos = null;
// ...
fileos = new FileOutputStream(newxmlfile);

OutputStream fileos = null;
// ...
fileos = new BufferedOutputStream(new FileOutputStream(newxmlfile));
