传递数据的列表从一个意图到另一个使用序列 [英] passing a list of data from one intent to another using serializable
问题描述
我想分析的数据的列表从一个意图另一个意图
不过，我的code， 我只是设法通过在ListView中的第一项。 我用一个log.d检查的项目，并认识到只有一个项目正在传递。 在我的列表视图有2项，比当我将它传递给我的下一个目标，只有一个项目在日志中显示出..
我在班上做了一个可序列化。 我做一个登录我的总结， 然而， 当我点击总之，那是不是所有的数据显示日志。
logcat的：

公共类fuelLogPojo实现Serializable {
fuelLogPojo 应实施任何 Parcelable 或序列化
束可以接受的自定义类，如果他们要么实现 Parcelable 或序列化， Parcelable 是速度更快，但更多的工作和序列化更容易实现，但速度较慢。
我会想象， fuelLogPojo扩展在这个例子中序列化，只是因为它容易设置，但你真的应该考虑 Parcelable
然后，你可以这样做：
dataBundle.putSerializable（pojoArrayList，pojoArrayList）;
sum.setArguments（包）;
编辑：
以下是如何访问 pojoArrayList 的总结。
名单，其中，fuelLogPojo＆GT; pojoArrayList =（名单＆LT; fuelLogPojo＆GT;）extras.getSerializable（pojoArrayList）;
I would like to parse a list of data from one intent to another intent
However, with my code, I'm only manage to pass the first item in the listview . I use a log.d to check for the items, and realised that only one items is being pass. In my listview there's 2 items,when I pass it over to my next intent, only one item was shown in the log..
I did a serializable in my class. I make a log in my summary, however, when I click on summary, the log that was shown in not all the data.
logcat:
01-28 18:20:49.218: D/Bundle(20278): bundle : Bundle[{clickedpreOdometer=, clickedID=2, clickedCost= 12.0, clickedDate=27/12/2014, pojoArrayList=[com.example.fuellogproject.fuelLogPojo@43bf3f18, com.example.fuellogproject.fuelLogPojo@43bf5b68], clickedPump=3, clickedPrice=4, clickedFCon= 0.0, clickedOdometer=3}]

fuelLogpojo.java
public class fuelLogPojo implements Serializable{
fuelLogPojo should implement either Parcelable or Serializable
Bundles can accept custom classes, if they implement either Parcelable or Serializable, Parcelable is faster but more work to implement and Serializable is easier to implement, but slower.
I'm going to imagine that fuelLogPojo extends Serializable in this example, just because its easier to setup but you should really consider Parcelable
Then you can do this:
dataBundle.putSerializable("pojoArrayList", pojoArrayList);
sum.setArguments(bundle);
Also, you should reconsider the naming convention for your classes.
EDIT:
Here's how to access that pojoArrayList in summary.
List<fuelLogPojo> pojoArrayList = (List<fuelLogPojo>)extras.getSerializable("pojoArrayList");
