第一種

在本地生成AppuserManager.xml檔案，並且把物件轉成了xml格式

package com.example.hasee.myxml;

import android.app.Activity;
import android.os.Bundle;
import android.os.Environment;
import android.util.Xml;
import android.view.View;
import android.widget.TextView;

import org.xmlpull.v1.XmlSerializer;

import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;

public class MainActivity extends Activity {

    List<AppuserManager> list;
    private TextView tv_text;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        tv_text = (TextView)findViewById(R.id.tv_text);
        list = new ArrayList<AppuserManager>();
       
            AppuserManager ap = new AppuserManager("appuser", "*", "ID=1",
                    "updatetime desc", 0, 0);
            list.add(ap);
    }


    public void click(View v){
        //使用序列化器生成xml檔案
        //1、得到xml序列化器物件
        XmlSerializer xs = Xml.newSerializer();
        //2、設定序列化器的輸出流
        File file = new File(Environment.getExternalStorageDirectory(),"AppuserManager.xml");
        FileOutputStream fos;


        try {
            fos = new FileOutputStream(file);

            xs.setOutput(fos, "utf-8");
            //3、開始生成xml檔案
            xs.startDocument("utf-8", true);
            xs.startTag(null, "Root");
//            for (int i = 0; i < list.size(); i++) {
                xs.startTag(null, "SubModelNode");
                xs.attribute("","ModelName","AppUser_mod");


                xs.startTag(null, "TableName");

                xs.text(list.get(0).getTableName());
                xs.endTag(null, "TableName");

                xs.startTag(null, "Fields");
                xs.attribute("","DataType","String");
                xs.text(list.get(0).getFields());
                xs.endTag(null, "Fields");

                xs.startTag(null, "Where");
                xs.attribute("","DataType","String");
                xs.endTag(null, "Where");

                xs.startTag(null, "OrderBy");
                xs.attribute("","DataType","String");
                xs.text(list.get(0).getOrderBy());
                xs.endTag(null, "OrderBy");

                xs.startTag(null, "PageIndex");
                xs.attribute("","DataType","Int32");// xs.attribute 一定要在xs.text 的上面否則就報錯
                xs.text(list.get(0).getPageIndex()+"");
                xs.endTag(null, "PageIndex");

                xs.startTag(null, "PageSize");
            xs.attribute("","DataType","Int32");
            xs.text(list.get(0).getPageSize()+"");
                xs.endTag(null, "PageSize");

                xs.endTag(null, "SubModelNode");
//            }/////////////////////

            xs.endTag(null, "Root");
            xs.endDocument();
            tv_text.setText(fos.toString());
            fos.close();
        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalArgumentException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IllegalStateException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

    }

}

第二種：只是把物件轉成了 xml格式，並不寫在檔案裡

package com.example.hasee.myxml;

import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;

import com.thoughtworks.xstream.XStream;

/**

 */
public class MainActivity2 extends Activity{

    private TextView tv_text;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        tv_text = (TextView)findViewById(R.id.tv_text);

        AppuserManager ap = new AppuserManager("appuser", "*", "ID=1",
                "updatetime desc", 0, 0);

        /*//把物件轉化為 XML
        XStream xstream1 = new XStream();
        String string = xstream1.toXML( ap ) ;
        System.out.println( "sss"+ string );
        tv_text.setText(string);*/

        //把物件轉化為 XML,並且設定別名
        XStream xstream2 = new XStream();
        xstream2.alias( "Root" , AppuserManager.class) ;   //修改別名
        String string2 = xstream2.toXML( ap ) ;//把最外層 標籤com.example.hasee.myxml 改成Root
        System.out.println(  string2 );
        tv_text.setText(string2);

    }
}

 /**

     */
    public String produceXml(ArrayList<TableManager> list, String attr_modelName){

        StringWriter stringWriter = new StringWriter();

            XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
            XmlSerializer xmlSerializer = factory.newSerializer();
            // 設定輸出流物件
            xmlSerializer.setOutput(stringWriter);

            xmlSerializer.startDocument("utf-8", true);
            xmlSerializer.startTag(null, "Root");
            for(int i=0;i<list.size();i++){


                xmlSerializer.startTag(null, "SubModelNode");
                xmlSerializer.attribute("","ModelName",attr_modelName);


                xmlSerializer.startTag(null, "TableName");
                xmlSerializer.attribute("","DataType","String");
                xmlSerializer.text(list.get(i).getTableName());
                xmlSerializer.endTag(null, "TableName");

                xmlSerializer.attribute("","DataType","String");
                xmlSerializer.text(list.get(i).getFields());

                xmlSerializer.startTag(null, "Where");
                xmlSerializer.attribute("","DataType","String");
                xmlSerializer.text((list.get(i).getWhere()));
                xmlSerializer.endTag(null, "Where");

                xmlSerializer.startTag(null, "OrderBy");
                xmlSerializer.attribute("","DataType","String");
                xmlSerializer.text((list.get(i).getOrderBy()));
                xmlSerializer.endTag(null, "OrderBy");

                xmlSerializer.startTag(null, "PageIndex");
                xmlSerializer.attribute("","DataType","Int32");// xs.attribute 一定要在xs.text 的上面否則就報錯
                xmlSerializer.text((list.get(i).getPageIndex()+""));
                xmlSerializer.endTag(null, "PageIndex");

                xmlSerializer.startTag(null, "PageSize");
                xmlSerializer.attribute("","DataType","Int32");

            }
            xmlSerializer.endTag(null, "Root");
            xmlSerializer.endDocument();
        } catch (Exception e) {
            e.printStackTrace();
        }

        return stringWriter.toString();

此方法的應用

ArrayList<TableManager> list = new ArrayList<TableManager>();
TableManager ap = new TableManager("appuser", "*", "ID=1",
        "updatetime desc", 0, 0);
TableManager ap1 = new TableManager("apimanage", "*", "ID=1",
        "updatetime desc", 0, 0);
list.add(ap);
list.add(ap1);
XmlUtils xu = new XmlUtils();
String s = xu.produceXml(list,"AppUser_mod");
