安卓如何生成xml文件數(shù)據(jù)

注意這里需要設(shè)置SD卡的權(quán)限

public void onClick(View arg0) {

//創(chuàng)建序列化XML數(shù)據(jù)的對(duì)象

XmlSerializer xml=Xml.newSerializer();

//創(chuàng)建目標(biāo)文件對(duì)象

File file= new File(Environment.getExternalStorageDirectory(),"stuinfo");

//創(chuàng)建文檔輸出流對(duì)象

FileOutputStream fos=null;

try {

fos = new FileOutputStream(file);

//設(shè)置輸出時(shí)候的編碼集

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

//設(shè)置輸出文檔為獨(dú)立的XML

xml.startDocument("utf-8", true);

//設(shè)置根開始標(biāo)簽

xml.startTag(null, "students");

//循環(huán)生成student元素

for(int i=0;i<list_name.size();i++)

{

xml.startTag(null, "student");

xml.startTag(null, "name");

xml.text(list_name.get(i));

xml.endTag(null, "name");

xml.startTag(null, "sex");

xml.text(list_sex.get(i));

xml.endTag(null, "sex");

xml.startTag(null, "age");

xml.text(list_age.get(i));

xml.endTag(null, "age");

xml.startTag(null, "tel");

xml.text(list_tel.get(i));

xml.endTag(null, "tel");

xml.endTag(null, "student");

}

//設(shè)置根結(jié)束標(biāo)簽

xml.endTag(null, "students");

//設(shè)置文檔結(jié)束

xml.endDocument();

//釋放資源

fos.close();
