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:

	<span style="white-space:pre">			</span>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:

<span style="white-space:pre">		</span>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<ShopData> CREATOR = new Parcelable.Creator<ShopData>() {

		public ShopData createFromParcel( Parcel in ){
			return new ShopData(in);
		}

		public ShopData[] newArray( int size){
			return new ShopData[size];
		}
	};

	@Override
	public int describeContents() {
		return 0;
	}

	@Override
	public 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:

	<span style="white-space:pre">			</span>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:

<span style="white-space:pre">		</span>Intent intent = getIntent();
		ShopData data = intent.getParcelableExtra("detail");
