在Android中的不同Activity之間傳遞對象，我們可以考慮采用Bundle.putSerializable(Key,Object);也可以考慮采用Bundle.putParcelable(Key, Object);其中前面一種方法中的Object要實現Serializable接口，后面一種方法中的Object要實現Parcelable接口。下面我們以一個完整的例子來說明。 1.新建一個Android的工程，其中該工程的目錄結構如下圖：  2.修改main.xml布局文件。布局文件的源碼如下： ~~~ <?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="@string/hello" /> <Button android:id="@+id/serButton" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Serializable"/> <Button android:id="@+id/parButton" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Parcelable"/></LinearLayout> ~~~ 3.在工程的src目錄下新建一個實體類包，命名為com.andy.entity.同時在該package中添加兩個實體類，一個是Person.java，該類實現Serializable接口；一個是Police.java，該類實現Parcelable接口。代碼分別如下： Person.java: ~~~ package com.andy.entity;import java.io.Serializable;public class Person implements Serializable { private static final long serialVersionUID = -6919461967497580385L; 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; }} ~~~ Police.java: ~~~ package com.andy.entity;import android.os.Parcel;import android.os.Parcelable;public class Police implements Parcelable { private String name; private int workTime; public String getName() { return name; } public void setName(String name) { this.name = name; } public int getWorkTime() { return workTime; } public void setWorkTime(int workTime) { this.workTime = workTime; } public static final Parcelable.Creator<Police> CREATOR = new Creator<Police>() { @Override public Police createFromParcel(Parcel source) { Police police = new Police(); police.name = source.readString(); police.workTime = source.readInt(); return police; } @Override public Police[] newArray(int size) { return new Police[size]; } }; @Override public int describeContents() { return 0; } @Override public void writeToParcel(Parcel parcel, int flags) { parcel.writeString(name); parcel.writeInt(workTime); }} ~~~ 4.在包com.andy.testdemo中修改TestActivity.java類，同時在該包中添加類SerializableDemo和ParcelableDemo，分別繼承了Activity類和分別顯示Person對象和Police對象的數據。代碼如下： ~~~ package com.andy.testdemo;import com.andy.entity.Person;import com.andy.entity.Police;import android.app.Activity;import android.content.Intent;import android.os.Bundle;import android.view.View;import android.widget.Button;public class TestActivity extends Activity { private Button sButton,pButton; public final static String SER_KEY = "com.andy.ser"; public final static String PAR_KEY = "com.andy.par"; /**Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); sButton = (Button)findViewById(R.id.serButton); sButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { SerializeMethod(); } }); pButton = (Button)findViewById(R.id.parButton); pButton.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { PacelableMethod(); } }); } /*** Serializeable傳遞對象的方法 */ private void SerializeMethod(){ Person mPerson = new Person(); mPerson.setName("andy"); mPerson.setAge(26); Intent mIntent = new Intent(this,SerializableDemo.class); Bundle mBundle = new Bundle(); mBundle.putSerializable(SER_KEY,mPerson); mIntent.putExtras(mBundle); startActivity(mIntent); } /*** Pacelable傳遞對象方法 */ private void PacelableMethod(){ Police mPolice = new Police(); mPolice.setName("I am Police"); mPolice.setWorkTime(2008); Intent mIntent = new Intent(this,ParcelableDemo.class); Bundle mBundle = new Bundle(); mBundle.putParcelable(PAR_KEY, mPolice); mIntent.putExtras(mBundle); startActivity(mIntent); }} ~~~ SerializableDemo.java類 ~~~ package com.andy.testdemo;import com.andy.entity.Person;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class SerializableDemo extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView mTextView = new TextView(this); Person mPerson = (Person)getIntent().getSerializableExtra(TestActivity.SER_KEY); mTextView.setText("You name is: " + mPerson.getName() + "/n"+ "You age is: " + mPerson.getAge()); setContentView(mTextView); }} ~~~ ParcelableDemo.java類： ~~~ package com.andy.testdemo;import com.andy.entity.Police;import android.app.Activity;import android.os.Bundle;import android.widget.TextView;public class ParcelableDemo extends Activity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); TextView mTextView = new TextView(this); Police mPolice = (Police)getIntent().getParcelableExtra(TestActivity.PAR_KEY); mTextView.setText("Police name is: " + mPolice.getName()+"/n"+ "WorkTime is: " + mPolice.getWorkTime() + "/n"); setContentView(mTextView); }} ~~~ 5.在AndroidManifest.xml文件中為新添加的兩個Activity進行注冊。 ~~~ <?xml version="1.0" encoding="utf-8"?><manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andy.testdemo" android:versionCode="1" android:versionName="1.0"> <application android:icon="@drawable/icon" android:label="@string/app_name"> <activity android:name=".TestActivity" 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=".SerializableDemo"/> <activity android:name=".ParcelableDemo"/> </application> <uses-sdk android:minSdkVersion="8" /></manifest> ~~~ 6.運行程序查看效果圖： 【1】主界面截圖：  【2】點擊Serializable按鈕的效果  【3】點擊Parcelable按鈕的效果  ========================================================================= 以上是如何采用Intent在不同的Activity之間傳遞對象的例子。
