Activity间利用Bundle传递ArrayList

目的:
Activity间传递ArrayList<HashMap<String,String>>
方法:
1 利用bundle.putSerializable("arrayList",arrayList)添加欲传送的ArrayList
2 利用intent.putExtras(bundle)添加Bundle
3 利用startActivity(intent)启动下一个Activity

//跳转前Activity
package cn.com.brave;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.Map;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class TestArrayListHashMapActivity extends Activity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button button=(Button) findViewById(R.id.button);
        button.setOnClickListener(new View.OnClickListener() {			
			@Override
			public void onClick(View v) {
				    Map<String, String> map1 = new HashMap<String, String>();
			        map1.put("name", "亮哥");
			        Map<String, String> map2 = new HashMap<String, String>();
			        map2.put("age", "25");
			        Map<String, String> map3 = new HashMap<String, String>();
			        map3.put("trait", "帅气");
			      
			        ArrayList<Map<String, String>> arrayList = new ArrayList<Map<String, String>>();
			        arrayList.add(map1);
			        arrayList.add(map2);
			        arrayList.add(map3);
			     
			        Bundle bundle = new Bundle();
			        bundle.putSerializable("arrayList", arrayList);
			        
			        Intent intent = new Intent(TestArrayListHashMapActivity.this, SecondActivity.class);
			        intent.putExtras(bundle);
			        startActivity(intent);			
			      
			}
		});
    }
}

//跳转后Activity
package cn.com.brave;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.Iterator;
import java.util.Set;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.widget.Toast;
public class SecondActivity extends Activity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		Intent intent = getIntent();
		Bundle buldle = intent.getExtras();		
		ArrayList<HashMap<String, String>> list =((ArrayList<HashMap<String, String>>) buldle.getSerializable("arrayList"));
		for(Iterator<HashMap<String, String>> it=list.iterator();it.hasNext();){
			HashMap<String, String> tempMap=it.next();
			Set<String> set=tempMap.keySet();
			for(Iterator<String> ito=set.iterator();ito.hasNext();){
				String s=ito.next();
				System.out.println(s+"="+tempMap.get(s));
			}
		}		
		Toast.makeText(this, "跳转成功", 0).show();		
	}
}


//备注:
//布局文件很简单,只有一个Button.在此略去main.xml文件
