如何使用意图传递自定义列表对象

-1

我正在研究Android应用程序，并且我想通过意向将一个Cutom列表对象传递给其他活动。我已经使该CustomList类实现Serializable接口。并使用下面的代码通过发送意图的数据：如何使用意图传递自定义列表对象

FeedList mSelectedFeedList = mFeedItemList.get(position); 
Intent intent = new Intent(mContext, SingleFeedPage.class);           intent.putExtra("feedItemPosition", listItemHolder.mSelectedPosition); 
intent.putExtra("action_id", mSelectedFeedList.getmActionId()); 
intent.putExtra("feedList", mSelectedFeedList);

当我通过intent我提示以下错误：发送此mSelectedFeedList：

java.lang.RuntimeException: Parcelable encountered IOException writing serializable object (name = com.socialengineaddons.mobileapp.classes.common.utils.FeedList)

下面是我的代码FeedList.java

非常感谢高级!!!

PL份额完整的堆栈跟踪 –

也有着FeedList类.. – Sachin

考虑实现Parcelable代替Serializable接口，见[此答案（http://stackoverflow.com/a/23647471/5015207） – 0X0nosugar

您必须使用parcelable类。

public class Student implements Parcelable{ 
     private String id; 
     private String name; 


     // Constructor 
     public Student(String id, String name){ 
      this.id = id; 
      this.name = name; 

     } 
     // Getter and setter methods 
     ......... 
     ......... 

     // Parcelling part 
     public Student(Parcel in){ 
      String[] data = new String[3]; 

      in.readStringArray(data); 
      this.id = data[0]; 
      this.name = data[1]; 

     } 

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

     @Override 
     public void writeToParcel(Parcel dest, int flags) { 
      dest.writeStringArray(new String[] {this.id, 
               this.name }); 
     } 
     public static final Parcelable.Creator CREATOR = new Parcelable.Creator() { 
      public Student createFromParcel(Parcel in) { 
       return new Student(in); 
      } 

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

使用：

intent.putExtra("student", new Student("1","Mike"));

获取数据：

Bundle data = getIntent().getExtras(); 
Student student = (Student) data.getParcelable("student");

或者你可以使用这个库：

https://github.com/johncarl81/parceler

或者使用序列化：

public class Student implements Serializable { 
     private String id; 
     private String name; 



     public Student(String id, String name){ 
      this.id = id; 
      this.name = name; 

     } 
     public string getId() { 
      id; 
     } 


     public string setName() { 
     name; 
     } 

    }

尝试通过可序列化;

Bundle bundle = new Bundle(); 
bundle.putSerializable("student", new Student("1","Mike")); 
intent.putExtras(bundle);

得到：

Intent intent = this.getIntent(); 
Bundle bundle = intent.getExtras(); 

Student st=(Student)bundle.getSerializable("value");

让您FeedListParcelable类。使用Parcelabler工具创建Parcelable类。

然后把意图这样的 -

intent.putExtra("feedList", mSelectedFeedList);

收到像这个 -

Bundle data = getIntent().getExtras(); 
Feedlist feedlist= (FeedList) data.getParcelable("feedList");
