android 对象序列化

Android 对象序列化Parcelable 使用实例：

1.发送数据类：

import android.app.Activity;

import android.content.Context;

import android.content.Intent;

import .Uri;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.LinearLayout;

public class A extends Activity {

public A(){}

@Override

public void onDestroy()

{

}

@Override

protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);

Button button = new Button(this);

button.setText("go actB");

button.setOnClickListener(new OnClickListener() {

@Override

public void onClick(View v) {

Person mPerson = new Person();

mPerson.setName("tom");

mPerson.setAge(25);

Intent mIntent = new Intent(A.this, B.class);

Bundle mBundle = new Bundle();

mBundle.putParcelable("key", mPerson);

mIntent.putExtras(mBundle);

startActivity(mIntent);

}

});

LinearLayout layout = new LinearLayout(this);

layout.addView(exitBtn);

this.setContentView(layout);

}

}

2.接收数据类：

import android.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.LinearLayout;

import android.widget.TextView;

public class B extends Activity

{

@Override

protected void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

TextView textView = new TextView(this);

Person mPerson = (Person)getIntent().getParcelableExtra("key");

Log.d("param ","***name = " + mPerson.getName() + " age = " +

mPerson.getAge());

textView.setText("name = " + mPerson.getName() + " age = " +

mPerson.getAge());

layout.addView(textView);

this.setContentView(layout);

}

}

3.实例化对象类：

import android.os.Parcel;

import android.os.Parcelable;

import android.util.Log;

public class Person implements Parcelable

{

private String name;

private int age;

private static final String TAG = "Parcelable";

public String getName()

{

return name;

}

public void setName(String name)

{

= name;

}

public int getAge()

{
