在Android中生成xml文件真的很簡單，下面提供2中方法，一種是通過String寫入到文件，另外一種是通過XML 的 XmlSerializer.

以後遇到Android寫xml內容就不會困惑了

1、通過string寫入文件

String name=mEtName.getText().toString();
String age=mEtAge.getText().toString();
String Id=mEtID.getText().toString();
File file=new File(Environment.getExternalStorageDirectory(),"info.xml");
try{
    FileOutputStream fos=new FilOutputStream(file);
    
    StringBuffer sb=new StringBuffer();
    //開始寫入xml裏的內容
    sb.append("<?xml version=‘1.0‘ encoding=‘utf-8‘ standalone=‘true‘ ?>");
    sb.append("<info>");
    sb.append("<student id=‘"+id+"‘>");
    sb.append("<name>"+name+"</name>");
    sb.append("<age>"+age+"</age>");
    sb.append("</student>");
    sb.append("</info>");
    
    fos.write(sb.toString().getBytes());
    fos.close;//關閉流
   }catch(Exception e){
       e.printStackTrace();
   }

2、通過Android的util裏的XML類來寫入

String name=.getText().toString()String age=.getText().toString()String Id=.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(); //關閉流

}catch(Exception e){

e.printStackTrace();

}
