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();
}
