package com.android.myintent;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.Button;public class Main extends Activity { /** Called when the activity is first created. */ private Button button; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); button = (Button) this.findViewById(R.id.button); button.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub // 声明一个意图 Intent intent = new Intent(); intent.setClass(Main.this, OtherActivity.class); OtherActivity.age = 23; OtherActivity.name = "jack"; startActivity(intent); } }); }}?
