package com.example.giacomob.myapplication;

import android.content.Context;
import android.content.Intent;
import android.content.res.AssetManager;

import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

import java.io.InputStream;

public class ReadXMLFile {

     public static void readXMLFile(Context context) {

        try {
          //  Log.i("MyActivity", "casa");

            AssetManager assetManager = context.getAssets();
            InputStream is = assetManager.open("infofermata.xml");
            DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            Document doc = dBuilder.parse(is);

           // String filePath = "assets/infofermata.xml";
            //File fXmlFile = new File(filePath);
            //DocumentBuilderFactory dbFactory = DocumentBuilderFactory.newInstance();
            //DocumentBuilder dBuilder = dbFactory.newDocumentBuilder();
            //Document doc = dBuilder.parse(fXmlFile);

            //optional, but recommended
            //read this - http://stackoverflow.com/questions/13786607/normalization-in-dom-parsing-with-java-how-does-it-work
            doc.getDocumentElement().normalize();

            System.out.println("Root element :" + doc.getDocumentElement().getNodeName());

            NodeList nList = doc.getElementsByTagName("fermata");

            System.out.println("----------------------------");

            for (int temp = 0; temp < nList.getLength(); temp++) {

                Node nNode = nList.item(temp);

                System.out.println("\nCurrent Element :" + nNode.getNodeName());
               // Log.i("MyActivity", "casa");

                if (nNode.getNodeType() == Node.ELEMENT_NODE) {

                    Element eElement = (Element) nNode;

                   // System.out.println("Staff id : " + eElement.getAttribute("id"));

                   // String stringidfermata = "Id Fermata : " + eElement.getElementsByTagName("idfermata").item(0).getTextContent()"";

                   // Log.i("MyActivity", "\"Id Fermata : \" + eElement.getElementsByTagName(\"idfermata\").item(0).getTextContent()");
                    System.out.println("Id Fermata : " + eElement.getElementsByTagName("idfermata").item(0).getTextContent());
                    String testo1 = eElement.getElementsByTagName("idfermata").item(0).getTextContent();
          //I would to switch this string in another activiy

                    System.out.println(testo1); //provo per vedere se stampa quello che ho messo nella variabile "testo1"
                    System.out.println("Naziome : " + eElement.getElementsByTagName("nazione").item(0).getTextContent());
                    System.out.println("Paese : " + eElement.getElementsByTagName("paese").item(0).getTextContent());
                    System.out.println("Via : " + eElement.getElementsByTagName("via").item(0).getTextContent());


                }

                is.close();
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }


}

I would to switch the string "testo1" in another acrivity called "acivity_page1.xml"

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:weightSum="1">

    <TextView
        android:layout_width="182dp"
        android:layout_height="wrap_content"
        android:textAppearance="?android:attr/textAppearanceLarge"
        android:text="Ciaoooo"
        android:id="@+id/textView2"
        android:layout_gravity="center_horizontal"
        android:layout_weight="0.29" />
</LinearLayout>

called by "Page1.java"

package com.example.giacomob.myapplication;

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

/**
 * Created by Giacomo B on 05/08/2015.
 */
public class Page1 extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_page1);
    }
    }

The MainActivity is:

package com.example.giacomob.myapplication;

import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;


public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ReadXMLFile.readXMLFile(this);
        Button b_load=(Button)findViewById(R.id.button_send);
        b_load.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View arg0) {
                Intent openPage1 = new Intent(MainActivity.this, Page1.class);
                startActivity(openPage1);
            }
        });
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.menu_main, menu);
        return true;
    }

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle action bar item clicks here. The action bar will
        // automatically handle clicks on the Home/Up button, so long
        // as you specify a parent activity in AndroidManifest.xml.
        int id = item.getItemId();

        //noinspection SimplifiableIfStatement
        if (id == R.id.action_settings) {
            return true;
        }

        return super.onOptionsItemSelected(item);
    }
}

How can I show this string on video in activity_page1?? please, help me.. thanks
