android 中生成xml文件

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

    

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();
    //开始写入xml里的内容
    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;//关闭流
   }catch(Exception e){
       e.printStackTrace();
   }

 

2、通过Android的util里的XML类来写入

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(); //关闭流

}catch(Exception e){

    e.printStackTrace();

}
