安卓如何生成xml文件數據

注意這里需要設置SD卡的權限

public void onClick(View arg0) {

//創建序列化XML數據的對象

XmlSerializer xml=Xml.newSerializer();

//創建目標文件對象

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

//創建文檔輸出流對象

FileOutputStream fos=null;

try {

fos = new FileOutputStream(file);

//設置輸出時候的編碼集

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

//設置輸出文檔為獨立的XML

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

//設置根開始標簽

xml.startTag(null, "students");

//循環生成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");

}

//設置根結束標簽

xml.endTag(null, "students");

//設置文檔結束

xml.endDocument();

//釋放資源

fos.close();
