Android實現Parcelable對象序列化的實例

bundle.putParcelable可以實現傳遞對象，但是這個對象的類必須實現Parcelable接口才能夠使用。

下面是一個簡單的在Activity之間傳遞對象的例子。

parcel實現參數的序列化，把類對象序列化為齊位的二進制流，提高傳輸的效率。

Parcelable類。最主要的類，也就是我們要傳送的對象的類，需要實現Parcelable接口。

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

public class BenParcelable implements Parcelable {

public String name;

public int age;

public String profession;

public BenParcelable(String name, int age, String profession) {
this.name = name;
this.age = age;
this.profession = profession;
}

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;
}

public String getprofession() {
return profession;
}

public void setprofession(String profession) {
this.profession = profession;
}

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

@Override
public void writeToParcel(Parcel parcel, int flag) {
parcel.writeString(name);
parcel.writeInt(age);
parcel.writeString(profession);
}

public static final Creator<BenParcelable> CREATOR = new Creator<BenParcelable>() {
public BenParcelable createFromParcel(Parcel in) {
return new BenParcelable(in);
}

public BenParcelable[] newArray(int size) {
return new BenParcelable[size];
}
};

private BenParcelable(Parcel in) {
name = in.readString();
age = in.readInt();
profession = in.readString();
}
}
