在Android中生成xml文件真的很简单，下面提供2中方法，一种是通过String写入到文件，另外一种是通过XML 的 XmlSerializer.

以后遇到Android写xml内容就不会困惑了

1、通过string写入文件

Stringname=mEtName.getText().toString();Stringage=mEtAge.getText().toString();StringId=mEtID.getText().toString();Filefile=newFile(Environment.getExternalStorageDirectory(),"info.xml");try{FileOutputStreamfos=newFilOutputStream(file);StringBuffersb=newStringBuffer();//开始写入xml里的内容sb.append("<?xmlversion='1.0'encoding='utf-8'standalone='true'?>");sb.append("<info>");sb.append("<studentid='"+id+"'>");sb.append("<name>"+name+"</name>");sb.append("<age>"+age+"</age>");sb.append("</student>");sb.append("</info>");fos.write(sb.toString().getBytes());fos.close;//关闭流}catch(Exceptione){e.printStackTrace();}

2、通过Android的util里的XML类来写入

Stringname=.getText().toString()Stringage=.getText().toString()StringId=.getText().toString()

XmlSerializer xmlSerializer=XML.newSerializer();

try{

FileOutputStream fos=new FileOutputStream(new File(Environment.getExtrernalStorageDirectory,"info2.xml"));

xmlSerializer.setOutput(fos,"utf-8");

xmlSerializer.setStartDocument("utf-8",true);

xmlSerializer.setStartTag(null,"info");

xmlSerializer.setStartTag(null,"student");

xmlSerializer.attribute(null,"id",Id);

xmlSerializer.setStartTag(null,"name");

xmlSerializer.text(name);

xmlSerializer.setEndTag(null,"name");

xmlSerializer.setStartTag(null,"age");

xmlSerializer.text(age);

xmlSerializer.setEndTag(null,"age");

xmlSerializer.setEndTag(null,"student");

xmlSerializer.setEndTag(null,"info");

xmlSerializer.setEndDocument();


fos.close(); //关闭流

}catch(Exception e){

e.printStackTrace();

}
