Android Intent中如何传递对象，就我目前所知道的有两种方法：
一种是Bundle.putSerializable(Key,Object);
另一种是Bundle.putParcelable(Key, Object);
当然这些Object是有一定的条件的，前者是实现了Serializable接口，而后者是实现了Parcelable接口，为了让大家更容易理解我还是照常写了一个简单的Demo,大家就一步一步跟我来吧！
第一步：新建一个Android工程命名为ObjectTranDemo(类比较多哦)目录结构如下图：
?
第二步：修改main.xml布局文件(这里我增加了两个按钮)代码如下：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" ><TextView android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Welcome to Mr wei's blog." /><Button android:id="@+id/button1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Serializable"/><Button android:id="@+id/button2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Parcelable"/></LinearLayout>
?第三步：新建两个类一个是Person.java实现Serializable接口，另一个Book.java实现Parcelable接口，代码分别如下：
Person.java:
package com.tutor.objecttran; import java.io.Serializable; public class Person implements Serializable { private static final long serialVersionUID = -7060210544600464481L; private String name; private int age; 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; } }?Book.java:
package com.tutor.objecttran; import android.os.Parcel;import android.os.Parcelable; public class Book implements Parcelable { private String bookName; private String author; private int publishTime; public String getBookName() { return bookName; } public void setBookName(String bookName) { this.bookName = bookName; } public String getAuthor() { return author; } public void setAuthor(String author) { this.author = author; } public int getPublishTime() { return publishTime; } public void setPublishTime(int publishTime) { this.publishTime = publishTime; } public static final Parcelable.Creator<book> CREATOR = new Creator<book>() { public Book createFromParcel(Parcel source) { Book mBook = new Book(); mBook.bookName = source.readString(); mBook.author = source.readString(); mBook.publishTime = source.readInt(); return mBook; } public Book[] newArray(int size) { return new Book[size]; } }; public int describeContents() { return 0; } public void writeToParcel(Parcel parcel, int flags) { parcel.writeString(bookName); parcel.writeString(author); parcel.writeInt(publishTime); }}?第四步：修改ObjectTranDemo.java,并且新建两个Activity,一个是ObjectTranDemo1.java,别一个是ObjectTranDemo2.java.分别用来显示Person对像数据和Book对象数据，代码分别如下：
ObjectTranDemo.java:
package com.tutor.objecttran; import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button; public class ObjectTranDemo extends Activity implements OnClickListener { private Button sButton, pButton; public final static String SER_KEY = "com.tutor.objecttran.ser"; public final static String PAR_KEY = "com.tutor.objecttran.par"; public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); setupViews(); } // 我的一贯作风呵呵 public void setupViews() { sButton = (Button) findViewById(R.id.button1); pButton = (Button) findViewById(R.id.button2); sButton.setOnClickListener(this); pButton.setOnClickListener(this); } // Serializeable<a title="传递对象" href="http://www.android-study.com/jichuzhishi/191.html">传递对象</a>的方法 public void SerializeMethod() { Person mPerson = new Person(); mPerson.setName("frankie"); mPerson.setAge(25); Intent mIntent = new Intent(this, ObjectTranDemo1.class); Bundle mBundle = new Bundle(); mBundle.putSerializable(SER_KEY, mPerson); mIntent.putExtras(mBundle); startActivity(mIntent); } // Pacelable<a title="传递对象" href="http://www.android-study.com/jichuzhishi/191.html">传递对象</a>方法 public void PacelableMethod() { Book mBook = new Book(); mBook.setBookName("Android Tutor"); mBook.setAuthor("Frankie"); mBook.setPublishTime(2010); Intent mIntent = new Intent(this, ObjectTranDemo2.class); Bundle mBundle = new Bundle(); mBundle.putParcelable(PAR_KEY, mBook); mIntent.putExtras(mBundle); startActivity(mIntent); } // 铵钮点击事件响应 public void onClick(View v) { if (v == sButton) { SerializeMethod(); } else { PacelableMethod(); } }}?ObjectTranDemo1.java:
package com.tutor.objecttran; import android.app.Activity;import android.os.Bundle;import android.widget.TextView; public class ObjectTranDemo1 extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView mTextView = new TextView(this); Person mPerson = (Person) getIntent().getSerializableExtra( ObjectTranDemo.SER_KEY); mTextView.setText("You name is: " + mPerson.getName() + "/n" + "You age is: " + mPerson.getAge()); setContentView(mTextView); }}?ObjectTranDemo2.java:
package com.tutor.objecttran; import android.app.Activity;import android.os.Bundle;import android.widget.TextView; public class ObjectTranDemo2 extends Activity { public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView mTextView = new TextView(this); Book mBook = (Book) getIntent().getParcelableExtra( ObjectTranDemo.PAR_KEY); mTextView.setText("Book name is: " + mBook.getBookName() + "/n" + "Author is: " + mBook.getAuthor() + "/n" + "PublishTime is: " + mBook.getPublishTime()); setContentView(mTextView); }}?第五步：比较重要的一步啦，修改AndroidManifest.xml文件（将两个新增的Activity，ObjectTranDemo1,ObjectTranDemo2)申明一下代码如下(第14，15行):
?
<?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.tutor.objecttran" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".ObjectTranDemo" android:label="@string/app_name"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity> <activity android:name=".ObjectTranDemo1"></activity> <activity android:name=".ObjectTranDemo2"></activity> </application> <uses-sdk android:minSdkVersion="7" /></manifest>

OK!!!!1
