传递对象的列表从一个活动到Android的其他活动 [英] Pass list of objects from one activity to other activity in android

问题描述

我想从另一个活动传递对象的列表从一个活动。我有一个类SharedBooking下面： -

i want to pass a list of objects from one activity from another activity . I have one class SharedBooking Below :-

public class SharedBooking {

public int account_id;
public Double betrag;
public Double betrag_effected;
public int taxType;
public int tax;
public String postingText;
}

从调用活动

code： -

Code from Calling activity :-

public List<SharedBooking> SharedBookingList = new ArrayList<SharedBooking>();

public void goDivision(Context context, Double betrag, List<SharedBooking> bookingList)
{
    final Intent intent = new Intent(context, Division.class);  
    intent.putExtra(Constants.BETRAG, betrag);      
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);    
    context.startActivity(intent);      
}

在所谓的活动

code： -

COde on called activity :-

Bundle extras = getIntent().getExtras();
    if (extras != null)         
    {
        amount=extras.getDouble(Constants.BETRAG,0);
    }

我如何从一个活动发送SharedBooking的列表，并接受她上的其它活动。

How i send list of SharedBooking from one activity , and recieve that on other activity .

请给我建议任何可用的链接或样品code。

Please suggest me any usable link or sample code .

推荐答案

使用 parcelable 。这里是你将如何做到这一点：

Use parcelable. Here is how you will do it:

public class SharedBooking implements Parcelable{

    public int account_id;
    public Double betrag;
    public Double betrag_effected;
    public int taxType;
    public int tax;
    public String postingText;

    public SharedBooking() {
        account_id = 0;
        betrag = 0.0;
        betrag_effected = 0.0;
        taxType = 0;
        tax = 0;
        postingText = "";
    }

    public SharedBooking(Parcel in) {
        account_id = in.readInt();
        betrag = in.readDouble();
        betrag_effected = in.readDouble();
        taxType = in.readInt();
        tax = in.readInt();
        postingText = in.readString();
    }

    public int getAccount_id() {
        return account_id;
    }
    public void setAccount_id(int account_id) {
        this.account_id = account_id;
    }
    public Double getBetrag() {
        return betrag;
    }
    public void setBetrag(Double betrag) {
        this.betrag = betrag;
    }
    public Double getBetrag_effected() {
        return betrag_effected;
    }
    public void setBetrag_effected(Double betrag_effected) {
        this.betrag_effected = betrag_effected;
    }
    public int getTaxType() {
        return taxType;
    }
    public void setTaxType(int taxType) {
        this.taxType = taxType;
    }
    public int getTax() {
        return tax;
    }
    public void setTax(int tax) {
        this.tax = tax;
    }
    public String getPostingText() {
        return postingText;
    }
    public void setPostingText(String postingText) {
        this.postingText = postingText;
    }
    public int describeContents() {
        // TODO Auto-generated method stub
        return 0;
    }
    public void writeToParcel(Parcel dest, int flags) {
        dest.writeInt(account_id);
        dest.writeDouble(betrag);
        dest.writeDouble(betrag_effected);
        dest.writeInt(taxType);
        dest.writeInt(tax);
        dest.writeString(postingText);

    }

    public static final Parcelable.Creator<SharedBooking> CREATOR = new Parcelable.Creator<SharedBooking>()
    {
        public SharedBooking createFromParcel(Parcel in)
        {
            return new SharedBooking(in);
        }
        public SharedBooking[] newArray(int size)
        {
            return new SharedBooking[size];
        }
    };

}

传递数据：

Intent intent = new Intent(getApplicationContext(),YourActivity.class);
Bundle bundle = new Bundle();
bundle.putParcelable("data", sharedBookingObject);
intent.putExtras(bundle);
startActivity(intent);

检索数据：

Bundle bundle = getIntent().getExtras();
sharedBookingObject = bundle.getParcelable("data");
