Parcelable传个Map的简单应用

最简单的，主要是实现Parcelable的接口，重写那个CREATOR

 

测试用的接收信息Activity

package com.nico;

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.os.Parcelable;

public class Test extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent i = getIntent();
        Person p = i.getParcelableExtra("yes");
        System.out.println("---->"+p.name);
        System.out.println("---->"+p.map.size());
    }
}

 发送的Activity

package com.nico;

import java.util.HashMap;

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

public class TestNew extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Intent intent = new Intent();
        Person p = new Person();
        p.map = new HashMap<String,String>();
        p.map.put("yes", "ido");
        p.name="ok";
        intent.putExtra("yes", p);
        intent.setClass(this, Test.class);
        startActivity(intent);
    }
}

 Parcelable的实现类

package com.nico;

import java.util.HashMap;

import android.os.Parcel;
import android.os.Parcelable;

public class Person implements Parcelable {

    public HashMap<String,String> map = new HashMap<String,String> ();

    public String name ;
    @Override
    public int describeContents() {
        return 0;
    }

    @Override
    public void writeToParcel(Parcel dest, int flags) {

        dest.writeMap(map);
        dest.writeString(name);
    }
    public static final Parcelable.Creator<Person> CREATOR = new Parcelable.Creator<Person>() {

        @Override
        public Person createFromParcel(Parcel source) {
            Person p = new Person();
            p.map=source.readHashMap(HashMap.class.getClassLoader());
            p.name=source.readString();
            return p;
        }

        @Override
        public Person[] newArray(int size) {
            // TODO Auto-generated method stub
            return null;
        }
    };

}

Google了一下，说是图片的大小不能超过40k
