java-發送一個 arraylist 到 parent activity

發送一個 arraylist 到 parent activity

我想發送一個 arraylist 到 parent activity

private ArrayList<Receipt> receipts = new ArrayList<Receipt>();
 Intent data = new Intent();
 data. // what to do here?
setResult(RESULT_OK, data); 
//************************************

下面是簡單的代碼

public class Receipt {
    public String referenceNo;
    public byte[]   image;
    public String comments;
    public Date   createdOn;
    public Date   updatedOn;

如何在 intent 中添加，還有如何從 parent activity 裡檢索？

onActivityResult(final int requestCode, int resultCode, final Intent data)

最佳回答：

public class Receipt implements Serializable{
    public String referenceNo;
    public byte[]   image;
    public String comments;
    public long   createdOn;
    public long   updatedOn;
    //...
}

//Put the list in the intent
List<Receipt> list = ...
Intent data = new Intent();
data.putExtra("tag", list);

//Read the list from the intent:
list = (List<Receipt>) data.getSerializableExtra("tag");
