新建一个FirstAvtivity.java

package com.zhuguangwei;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

public class FirstActivity extends Activity {

private Button myButton;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

myButton = (Button) findViewById(R.id.myButton);

myButton.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

Intent intent = new Intent();

//Intent传递参数

intent.putExtra("testIntent", "123");

intent.setClass(FirstActivity.this, SecondActivity.class);

FirstActivity.this.startActivity(intent);

}

});

}

}

新建第二个SecondActivity.java

package com.zhuguangwei;

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.widget.TextView;

public class SecondActivity extends Activity{

private TextView myTextView;

@Override

protected void onCreate(Bundle savedInstanceState) {

// TODO Auto-generated method stub

super.onCreate(savedInstanceState);

setContentView(R.layout.other);

//使用Intent对象得到FirstActivity传递来的参数

Intent intent = getIntent();

String value = intent.getStringExtra("testIntent");

myTextView = (TextView) findViewById(R.id.myTextView);

myTextView.setText(value);

}

}

两个Activity都要在AndroidMenifest.xml中注册
