android pull creates xml file

pullCreating an xml file is very simple.

/设置生成xml编码格式
serializer.startDocument("UTF-8", false);
//设置xml 命名空间和根元素，任何元素都用这种方式创建
serializer.startTag(null, "classes");
//设置group的属性，设置元素的属性
serializer.attribute(null, "name", "一年级");
//创建xml元素的值
serializer.text("语文80");
//创建xml元素结束
serializer.endTag(null, "person");

The first parameter of the above method is the xml namespace.

The following is the code to generate simple xml:

private void pullCreateXml(){  
        try {  
            OutputStream outStream = openFileOutput("sax.xml",  Context.MODE_PRIVATE);  
            XmlSerializer serializer = Xml.newSerializer();  
            //输出流的编码格式  
            serializer.setOutput(outStream, "UTF-8");  
            //设置xml文件的编码格式，  
            /*第二个参数trues生成 tandalone='yes'   
             * false 则生成tandalone='no'  
             * 值 no 表示这个 XML 文档不是独立的而是依赖于外部所定义的一个 DTD.    
             * 值 yes 表示这个 XML 文档是自包含的(self-contained).  
             */  
            serializer.startDocument("UTF-8", false);  
            //设置xml 命名空间和根元素  
            serializer.startTag(null, "classes");  
            serializer.startTag(null, "group");  
            //设置group的属性  
            serializer.attribute(null, "name", "一年级");  
            serializer.attribute(null, "num", "10");  
            serializer.startTag(null, "person");  
            serializer.attribute(null, "name", "小明");  
            serializer.attribute(null, "age", "7");  
            serializer.startTag(null, "chinese");  
            serializer.text("语文80");  
            serializer.endTag(null, "chinese");  
              
            serializer.startTag(null, "english");  
            serializer.text("英语80");  
            serializer.endTag(null, "english");  
              
            serializer.endTag(null, "person");  
            serializer.endTag(null, "group");  
            serializer.endTag(null, "classes");  
            //数据写入到xml文件中  
            serializer.flush();  
            //关闭流  
            outStream.close();  
              
        } catch (FileNotFoundException e) {  
            e.printStackTrace();  
        } catch (IllegalArgumentException e) {  
            e.printStackTrace();  
        } catch (IllegalStateException e) {  
            e.printStackTrace();  
        } catch (IOException e) {  
            e.printStackTrace();  
        }  
    }

The generated xml is not formatted, that is, there are no line breaks, tabs and other formatted auxiliary symbols

<?xml version=&#39;1.0&#39; encoding=&#39;UTF-8&#39; standalone=&#39;no&#39; ?><classes><group name="一年级" num="10">
<person name="小明" age="7"><chinese>语文80</chinese><english>英语80</english></person></group></classes>
