bundle.putParcelable可以实现传递对象,但是这个对象的类必须实现Parcelable接口才能够使用。
下面是一个简单的在Activity之间传递对象的例子。
parcel实现参数的序列化,把类对象序列化为齐位的二进制流,提高传输的效率。
Parcelable类。最主要的类,也就是我们要传送的对象的类,需要实现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();
}
}
