Intent 也可以传递对象的，例子如下：
MyParcelable.java 文件:
Java代码
package com.ldq.parcelable;
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 MyParcelable extends Activity {
private Button button;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Student student = new Student();
student._id = 1001;
student.name = "zhang";
student.sex = 1;
student.age = 10;
Intent intent = new Intent(MyParcelable.this,
AnotherActivity.class);
intent.putExtra("student", student);
startActivity(intent);
}
});
}
}
Student.java 文件:
Java代码
package com.ldq.parcelable;
import android.os.Parcel;
import android.os.Parcelable;
public class Student implements Parcelable {
public int _id;
public String name;
public int sex;
public int age;
Student(Parcel p) {
_id = p.readInt();
name = p.readString();
sex = p.readInt();
age = p.readInt();
}
Student() {
};
public static final Parcelable.Creator<Student> CREATOR = new Parcelable.Creator<Student>() {
public Student createFromParcel(Parcel p) {
return new Student(p);
}
public Student[] newArray(int size) {
return new Student[size];
}
};
public int describeContents() {
return 0;
}
public void writeToParcel(Parcel p, int flags) {
p.writeInt(_id);
p.writeString(name);
p.writeInt(sex);
p.writeInt(age);
}
}
AnotherActivity.java 文件:
Java代码
package com.ldq.parcelable;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class AnotherActivity extends Activity {
private TextView textView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main1);
Student s = getIntent().getParcelableExtra("student");
textView = (TextView) findViewById(R.id.textView1);
textView.setText("name:" + s.name + ",age:" + s.age);
}
}
AndroidManifest.xml 文件:
Xml代码
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.ldq.parcelable" android:versionCode="1"

<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity android:name=".AnotherActivity">
</activity>
</application>
</manifest>
main.xml 文件:
Xml代码
<?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"

</LinearLayout>
main1.xml 文件:
