android中Activity之间传递对象

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 plaincopy

1. Intent intent = new Intent();  
2.                 ShopData shopData = (ShopData)mAdapter.getItem(position);  
3. //              intent.putExtra("detail", shopData);  
4.                 Bundle bundle = new Bundle();  
5.                 bundle.putSerializable("shop", shopData);  
6.                 intent.putExtra("detail", shopData);  
7.                 intent.setClass(MainActivity.this, DetailShopActivity.class);  
8.                 MainActivity.this.startActivity(intent);  

取值的时候:

[java] view plaincopy

1. Intent intent = getIntent();  
2. //      ShopData data = intent.getParcelableExtra("detail");  
3.         ShopData data = (ShopData)intent.getSerializableExtra("detail");  

对于第二种方式:

[java] view plaincopy

1. import android.os.Parcel;  
2. import android.os.Parcelable;  
3.   
4. public class ShopData implements Parcelable{  
5.   
6.     public String shopId;  
7.     public String name;  
8.     public String url;  
9.     public String info;  
10.   
11.     public ShopData(Parcel in) {  
12.         readFromParcel(in);  
13.     }  
14.       
15.     public ShopData() {  
16.     }  
17.       
18.   
19.     public static final Parcelable.Creator<ShopData> CREATOR = new Parcelable.Creator<ShopData>() {  
20.           
21.         public ShopData createFromParcel( Parcel in ){  
22.             return new ShopData(in);  
23.         }  
24.           
25.         public ShopData[] newArray( int size){  
26.             return new ShopData[size];  
27.         }  
28.     };  
29.       
30.     @Override  
31.     public int describeContents() {  
32.         return 0;  
33.     }  
34.   
35.     @Override  
36.     public void writeToParcel(Parcel dest, int flags) {  
37.         dest.writeString(shopId);  
38.         dest.writeString(name);  
39.         dest.writeString(url);  
40.         dest.writeString(info);  
41.           
42.     }  
43.     public void readFromParcel( Parcel in ){  
44.         shopId = in.readString();  
45.         name = in.readString();  
46.         url = in.readString();  
47.         info = in.readString();  
48.     }  
49.       
50. }  

传递的时候这样写:

[java] view plaincopy

1.     Intent intent = new Intent();  
2.             ShopData shopData = (ShopData)mAdapter.getItem(position);  
3.             intent.putExtra("detail", shopData);  
4.             intent.putExtra("detail", shopData);  
5.             intent.setClass(MainActivity.this, DetailShopActivity.class);  
6.             MainActivity.this.startActivity(intent);  

取值的时候:

[java] view plaincopy

1. Intent intent = getIntent();  
2.         ShopData data = intent.getParcelableExtra("detail");
