第一个Activity:

package com.example.wjb.myapplication;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.Menu;import android.view.MenuItem;import android.view.View;import android.widget.Button;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Button btn = (Button) findViewById(R.id.button);        btn.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Intent i = new Intent(MainActivity.this, Act.class);                Bundle b=new Bundle();                b.putString("name","wujiabao");                b.putInt("age",21);                i.putExtras(b);//              或者是 i.putExtra("data",b);                                startActivity(i);            }        });    }}

第二个Activity:

package com.example.wjb.myapplication;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.widget.TextView;/** * Created by wjb on 2015/9/2. */public class Act extends Activity{    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.act);        TextView tv= (TextView) findViewById(R.id.textView);        Intent i = getIntent();        Bundle data=i.getExtras();//      参照上图的获取方法,Bundle data=i.getBundleExtra("data");        tv.setText(String.format("name=%s,age=%d", data.getString("name"), data.getInt("age")));    }}
