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:

Intent intent = new Intent();ShopData shopData = (ShopData)mAdapter.getItem(position);//intent.putExtra("detail", shopData);Bundle bundle = new Bundle();bundle.putSerializable("shop", shopData);intent.putExtra("detail", shopData);intent.setClass(MainActivity.this, DetailShopActivity.class);MainActivity.this.startActivity(intent);

取值的时候:

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

对于另外一种方式:

import android.os.Parcel;import android.os.Parcelable;public class ShopData implements Parcelable{public String shopId;public String name;public String url;public String info;public ShopData(Parcel in) {readFromParcel(in);}public ShopData() {}public static final Parcelable.Creator CREATOR = new Parcelable.Creator() {public ShopData createFromParcel( Parcel in ){return new ShopData(in);}public ShopData[] newArray( int size){return new ShopData[size];}};@Overridepublic int describeContents() {return 0;}@Overridepublic void writeToParcel(Parcel dest, int flags) {dest.writeString(shopId);dest.writeString(name);dest.writeString(url);dest.writeString(info);}public void readFromParcel( Parcel in ){shopId = in.readString();name = in.readString();url = in.readString();info = in.readString();}}

传递的时候这样写:

Intent intent = new Intent();ShopData shopData = (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:

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