前言：平时都是传递int或者string数据，这次需要传递List数据，记录一下方法

最开始是使用Bundle来传递，这种方法网上有很多教程，就不写了。一开始是成功的，确实是可以传递，但是过了几天我再打开的时候，对数据进行了修改后就失败了。于是换了个方法。

参考：Activity之间传递List数据

记录一下方法和示例代码，示例代码是上面链接的文章里的
1、创建实体类Bean,同时Bean要implements Serializable:

package com.example.intentlist;
 
import java.io.Serializable;
 
public class Bean implements Serializable {
	private int id;
	private String name;
	private int age;
 
	public Bean() {
 
	}
 
	public Bean(int id, String name, int age) {
		this.id = id;
		this.name = name;
		this.age = age;
	}
 
	public int getId() {
		return id;
	}
 
	public void setId(int id) {
		this.id = id;
	}
 
	public String getName() {
		return name;
	}
 
	public void setName(String name) {
		this.name = name;
	}
 
	public int getAge() {
		return age;
	}
 
	public void setAge(int age) {
		this.age = age;
	}
 
}

2、要传递的Activity:

package com.example.intentlist;
 
import java.io.Serializable;
import java.util.ArrayList;
import java.util.List;
 
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
 
public class MainActivity extends ActionBarActivity {
	List<Bean> lstBean;
 
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
 
		lstBean = new ArrayList<Bean>();
		Bean bean = new Bean(1, "张三", 12);
		lstBean.add(bean);
		Bean bean1 = new Bean(2, "李四", 13);
		lstBean.add(bean1);
		Bean bean2 = new Bean(3, "王五", 14);
		lstBean.add(bean2);
		Bean bean3 = new Bean(4, "赵六", 15);
		lstBean.add(bean3);
		((Button) findViewById(R.id.btn_next)).setOnClickListener(new OnClickListener() {
 
			@Override
			public void onClick(View arg0) {
				Intent intentPut = new Intent(MainActivity.this, IntentTestActivity.class);
				intentPut.putExtra("lstBean", (Serializable) lstBean);
				startActivity(intentPut);
			}
		});
 
	}
}

3、接收list的Activity:

package com.example.intentlist;
 
import java.util.List;
 
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.widget.TextView;
 
public class IntentTestActivity extends ActionBarActivity {
 
	@SuppressWarnings("unchecked")
	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_intent_test);
		Intent intentGet = getIntent();
		List<Bean> lstBean = (List<Bean>) intentGet.getSerializableExtra("lstBean");
		String result = "IntentTestActivity" + "\n";
		for (Bean bean : lstBean) {
			result += bean.getId() + "---" + bean.getName() + "---" + bean.getAge() + "\n";
		}
 
		((TextView) findViewById(R.id.tv_result)).setText(result);
	}
}
