如何使用 Bundle 传递数据？

package com.example.serilizaldemo;

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

public class MainActivity extends Activity {

	private TextView title;
	private TextView url;
	private Button button;
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		
		title = (TextView)this.findViewById(R.id.title);
		url = (TextView)this.findViewById(R.id.url);
		button = (Button)this.findViewById(R.id.button1);
		
		final Game game = new Game();
		game.setTitle(title.getText()+"");
		game.setUrl(url.getText()+"");
		
		button.setOnClickListener(new OnClickListener() {
			@Override
			public void onClick(View v) {
				// TODO Auto-generated method stub
				Intent intent = new Intent(MainActivity.this,SecondActiviity.class);
//				1 封装 序列化
				Bundle bundle = new Bundle();
				bundle.putSerializable("love", game);
				intent.putExtra("game", bundle);
				startActivity(intent);
			}
		});
		
		
		
	}

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

}

package com.example.serilizaldemo;

import java.io.Serializable;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.util.Log;

public class SecondActiviity extends Activity {

	private static final String Tag= "SecondActiviity";
	
	public SecondActiviity() {
		// TODO Auto-generated constructor stub
	}
	
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.second);
		
		Intent intent = getIntent();
		Bundle bundle = intent.getBundleExtra("game");
//		2  反序列化！ 取出数据。
		Serializable obj = bundle.getSerializable("love");
		if(obj != null && obj instanceof Game)
		{
			Game g = (Game)obj;
			Log.i(Tag, "--url="+g.getUrl());
			Log.i(Tag, "--title="+g.getTitle());
		}
		
		Log.i(Tag, "--title=");
		
		
	}

}

package com.example.serilizaldemo;

import java.io.Serializable;
import java.util.List;

//	实现 可序列化  实现 可续列话 接口
public class Game implements Serializable{

//	定义自己的序号
	private final static long serialVersionUID = 1234567890L;
	
	private String title;
	private String url;
	
	private long fileSize;
	
//	private List<Go> list;
	
	public Game() {
		// TODO Auto-generated constructor stub
	}

	public String getTitle() {
		return title;
	}

	public void setTitle(String title) {
		this.title = title;
	}

	public String getUrl() {
		return url;
	}

	public void setUrl(String url) {
		this.url = url;
	}

	public long getFileSize() {
		return fileSize;
	}

	public void setFileSize(long fileSize) {
		this.fileSize = fileSize;
	}
