我从webservice获得了很大的价值。我的回复就像XML实体字符引用一样。我正在使用strigescapeutils calss替换字符。我将我的回复存储在一个字符串中。我收到内存不足错误。我正在使用SAX解析器解析响应。我解析了该值并将其存储在bean的arraylist中。在arraylist值中将其添加到textview中。
执行此操作时出现此错误：内存不足错误。我不知道怎么做流。谁能告诉我怎么做？谁能举个例子？是否可以在bean和字符串的arraylist中添加大值？
这是我使用字符串解析器读取解析值：
xr.parse(new InputSource(new StringReader(webservicevalue)));
我收到此错误：

答案 0 :(得分：1)
好的，您正在从Web服务接收一些XML，并且您正在使用SAX解析此XML。 SAX是一种流式解析器，它只读取XML文档的块，因此允许最小化所需的内存。所以这部分程序按预期工作。
然后将数据存储在ArrayList中，这意味着在内存中。你没有说你要解析多少条目，但我认为这就是问题所在。您应该将条目存储在数据库中。因此，您应该使用ContentProvider。您可以找到一个保存和显示数据的好教程here - 官方记事本练习1。
