android页面间传递对象

android传递对象有两种方式:

一种是Serializable和Parcelable

对于第一种方式:

import java.io.Serializable;

public class ShopData implements Serializable {
public String shopId;
public String name;
public String url;
public String info;

public String getShopId() {
return shopId;
}

public void setShopId(String shopId) {
this.shopId = shopId;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

public String getUrl() {
return url;
}

public void setUrl(String url) {
this.url = url;
}

public String getInfo() {
return info;
}

public void setInfo(String info) {
this.info = info;
}

}

传递值的时候这样来传递:

[java] view plain copy

<spanstyle="white-space:pre"></span>Intentintent=newIntent();
ShopDatashopData=(ShopData)mAdapter.getItem(position);
//intent.putExtra("detail",shopData);
Bundlebundle=newBundle();
bundle.putSerializable("shop",shopData);
intent.putExtra("detail",shopData);
intent.setClass(MainActivity.this,DetailShopActivity.class);
MainActivity.this.startActivity(intent);

取值的时候: [java] view plain copy

<spanstyle="white-space:pre"></span>Intentintent=getIntent();
//ShopDatadata=intent.getParcelableExtra("detail");
ShopDatadata=(ShopData)intent.getSerializableExtra("detail");

对于第二种方式: [java] view plain copy

importandroid.os.Parcel;
importandroid.os.Parcelable;
publicclassShopDataimplementsParcelable{
publicStringshopId;
publicStringname;
publicStringurl;
publicStringinfo;
publicShopData(Parcelin){
readFromParcel(in);
}
publicShopData(){
}
publicstaticfinalParcelable.Creator<ShopData>CREATOR=newParcelable.Creator<ShopData>(){
publicShopDatacreateFromParcel(Parcelin){
returnnewShopData(in);
}
publicShopData[]newArray(intsize){
returnnewShopData[size];
}
};
@Override
publicintdescribeContents(){
return0;
}
@Override
publicvoidwriteToParcel(Parceldest,intflags){
dest.writeString(shopId);
dest.writeString(name);
dest.writeString(url);
dest.writeString(info);
}
publicvoidreadFromParcel(Parcelin){
shopId=in.readString();
name=in.readString();
url=in.readString();
info=in.readString();
}
}

传递的时候这样写: [java] view plain copy

<spanstyle="white-space:pre"></span>Intentintent=newIntent();
ShopDatashopData=(ShopData)mAdapter.getItem(position);
intent.putExtra("detail",shopData);
intent.putExtra("detail",shopData);
intent.setClass(MainActivity.this,DetailShopActivity.class);
MainActivity.this.startActivity(intent);

取值的时候: [java] view plain copy

<spanstyle="white-space:pre"></span>Intentintent=getIntent();
ShopDatadata=intent.getParcelableExtra("detail");
