Passing data through intent using Serializable

Question

I've implemented my class with serializable, but it still didn't work.

This is my class:

package com.ursabyte.thumbnail;  import java.io.Serializable;  import android.graphics.Bitmap;  public class Thumbnail implements Serializable {      private static final long serialVersionUID = 1L;     private String label = "";     private Bitmap bitmap;      public Thumbnail(String label, Bitmap bitmap) {         this.label = label;         this.bitmap = bitmap;     }      public void set_label(String label) {         this.label = label;     }      public String get_label() {         return this.label;     }      public void set_bitmap(Bitmap bitmap) {         this.bitmap = bitmap;     }      public Bitmap get_bitmap(){         return this.bitmap;     }      //  @Override     //  public int compareTo(Thumbnail other) {     //      if(this.label != null)     //          return this.label.compareTo(other.get_label());     //      else     //          throw new IllegalArgumentException();     //  }  } 

This is what I want to be passing.

List<Thumbnail> all_thumbs = new ArrayList<Thumbnail>(); all_thumbs.add(new Thumbnail(string, bitmap)); Intent intent = new Intent(getApplicationContext(), SomeClass.class); intent.putExtra("value", all_thumbs); 

But still it didn't work. I don't know how to use Parcelable, so I use this instead.

Answer 1

Try to pass the serializable list using Bundle.Serializable:

Bundle bundle = new Bundle(); bundle.putSerializable("value", all_thumbs); intent.putExtras(bundle); 

And in SomeClass Activity get it as:

Intent intent = this.getIntent(); Bundle bundle = intent.getExtras();  List<Thumbnail> thumbs=                (List<Thumbnail>)bundle.getSerializable("value");
