Android Studio添加Parcelable序列化小工具（快速提高开发效率）
&&&&&&&&Android Studio是google专门为开发Android提供的开发工具，在它内部可以直接的添加一些非常好用的开发小工具，这里就讲解怎样添加这些小工具，并且向大家推荐一个非常有用的对象传递时，必须要把对象序列化的接口Parcelable小工具;
&&&&&&&&&这里先介绍下 Android中实现序列化的两个选择：一是实现Serializable接口（是JavaSE本身就支持的），一是实现Parcelable接口（是Android特有功能，效率比实现Serializable接口高效，可用于Intent数据传递，也可以用于进程间通信（IPC））。实现Serializable接口非常简单，声明一下就可以了，而实现Parcelable接口稍微复杂一些，但效率更高，推荐用这种方法提高性能。
&&&&&&& 并且值得注意的是 Android中Intent传递对象也对应有两种方法：一是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。
package com.iqtogether.qxueyou.
import android.os.P
import android.os.P
* Created by chengguo on .
public class User implements Parcelable {
private String userId;
private String userN
private String userS
private int userA
public String getUserId() {
return userId;
public void setUserId(String userId) {
this.userId = userId;
public String getUserName() {
return userN
public void setUserName(String userName) {
this.userName = userN
public String getUserSex() {
return userS
public void setUserSex(String userSex) {
this.userSex = userS
public int getUserAge() {
return userA
public void setUserAge(int userAge) {
this.userAge = userA
public String getUserHome() {
return userH
public void setUserHome(String userHome) {
this.userHome = userH
private String userH
public int describeContents() {
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.userId);
dest.writeString(this.userName);
dest.writeString(this.userSex);
dest.writeInt(this.userAge);
dest.writeString(this.userHome);
public User() {
protected User(Parcel in) {
this.userId = in.readString();
this.userName = in.readString();
this.userSex = in.readString();
this.userAge = in.readInt();
this.userHome = in.readString();
public static final Parcelable.Creator&User& CREATOR = new Parcelable.Creator&User&() {
public User createFromParcel(Parcel source) {
return new User(source);
public User[] newArray(int size) {
return new User[size];
然后错误提示如下:
package com.iqtogether.qxueyou.
import android.os.P
import android.os.P
* Created by chengguo on .
public class House implements Parcelable {
public String getPrice() {
public void setPrice(String price) {
this.price =
public int describeContents() {
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.price);
public House() {
protected House(Parcel in) {
this.price = in.readString();
public static final Parcelable.Creator&House& CREATOR = new Parcelable.Creator&House&() {
public House createFromParcel(Parcel source) {
return new House(source);
public House[] newArray(int size) {
return new House[size];
package com.iqtogether.qxueyou.
import android.os.P
import android.os.P
* Created by chengguo on .
public class User implements Parcelable {
private String userId;
private String userN
private String userS
private int userA
private House userH
public House getUserHouse() {
return userH
public void setUserHouse(House userHouse) {
this.userHouse = userH
public String getUserId() {
return userId;
public void setUserId(String userId) {
this.userId = userId;
public String getUserName() {
return userN
public void setUserName(String userName) {
this.userName = userN
public String getUserSex() {
return userS
public void setUserSex(String userSex) {
this.userSex = userS
public int getUserAge() {
return userA
public void setUserAge(int userAge) {
this.userAge = userA
public String getUserHome() {
return userH
public void setUserHome(String userHome) {
this.userHome = userH
private String userH
public User() {
public int describeContents() {
public void writeToParcel(Parcel dest, int flags) {
dest.writeString(this.userId);
dest.writeString(this.userName);
dest.writeString(this.userSex);
dest.writeInt(this.userAge);
dest.writeParcelable(this.userHouse, flags);
dest.writeString(this.userHome);
protected User(Parcel in) {
this.userId = in.readString();
this.userName = in.readString();
this.userSex = in.readString();
this.userAge = in.readInt();
this.userHouse = in.readParcelable(House.class.getClassLoader());
this.userHome = in.readString();
public static final Creator&User& CREATOR = new Creator&User&() {
public User createFromParcel(Parcel source) {
return new User(source);
public User[] newArray(int size) {
return new User[size];
&& 好了这样就完成了Pacelable序列化小工具的添加和使用，是不是非常方便快捷呢！最后不要忘了，intent在
传递对象是使用的是Bundle.putParcelable(Key，Object)，而不是Bundle.putSerializable(Key，Object)。在接收对象时使用的是getIntent( ).getParcelableExter( Key),而不是getIntent( ).getSerializableExtera( Key);
&&&&祝大家工作愉快。
