Как отправить больше, чем 1 значение EditText, используя пакет ⇐ Android

[Anonymous]

Я разработал простую программу Android с двумя видами деятельности, в этом 1 -м деятельности содержится некоторые EditTexts и кнопку, а второе действие содержит одинаковое количество TextViews. /> mainactivity.java

package com.example.myweb;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;

public class MainActivity extends Activity {
public String EXTRA_MESSAGE = "com.example.myweb";
Button b;
EditText ed1,ed2,ed3,ed4;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

b =(Button)findViewById(R.id.send);
ed1 = (EditText)findViewById(R.id.edit_msg);
ed2=(EditText)findViewById(R.id.edit_msg1);
ed3=(EditText)findViewById(R.id.edit_msg3);
ed4=(EditText)findViewById(R.id.edit_msg4);

b.setOnClickListener(new OnClickListener() {

@Override
public void onClick(View v) {
// TODO Auto-generated method stub

Intent i = new Intent(MainActivity.this,Act2.class);
Bundle b=new Bundle();
String fname=ed1.getText().toString();
String lname=ed2.getText().toString();
String fon=ed3.getText().toString();
String city= ed4.getText().toString();

b.putString("Extra__fname", fname);
b.putString("Extra__lname", lname);
b.putString("Extra__fon", fon);
b.putString("Extra__city", city);

i.putExtras(b);
startActivity(i);

/*i.putExtra("EXTRA_MESSAGE", s);
startActivity(i);*/

}
});

}

}
< /code>

акт2.java

пакет com.example.myweb; < /p>

import org.w3c.dom.Text;

import android.os.Bundle;
import android.app.Activity;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
import android.widget.TextView;

public class Act2 extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.act2);

Intent i = getIntent();

Bundle b =i.getExtras();
String fname=i.getStringExtra("fname");
String lname=i.getStringExtra("lname");
String fon=i.getStringExtra("fon");
String city=i.getStringExtra("city");

// String text = i.getStringExtra("EXTRA_MESSAGE");

TextView t = (TextView)findViewById(R.id.tv1);
TextView t1 = (TextView)findViewById(R.id.tv2);
TextView t2 = (TextView)findViewById(R.id.tv3);
TextView t3 = (TextView)findViewById(R.id.tv4);

t.setText(fname);
t1.setText(lname);
t2.setText(fon);
t3.setText(city);

}
}
