Hi,
I'm trying to send an ArrayList<T> to another activity. The API
reference says this:
public Intent putExtra (String name, Serializable value)
to put an extra value that is Serializable, and:
public Serializable getSerializableExtra (String name)
To get the Serializable object. Also, we have the class ArrayList that
implements Serializable:
public class ArrayList extends AbstractList<E> implements Serializable
Cloneable List<E> RandomAccess
I added to the ArrayList<HashMap<String,Object>> image buttons and
Strings, e.g.:
ArrayList<HashMap<String,Object>> arraylist = enw
ArrayList<HashMap<String,Object>>();
HashMap<String,Object> item = new HashMap<String,Object>();
ImageButton imb = new ImageButton();
item.put("an image button", imb);
item.put("a string", "string1");
arraylist.add(item);
intent.putExtra(ToActivity.OPTIONS, arraylist);
startActivity(intent);
It does not say anything about if ImageButton is Serializable or not.
I get this error trying to receive the intent with this line for sure:
ArrayList<HashMap<String,Object>> data;
data = (ArrayList<HashMap<String,Object>>) intent.getSerializableExtra(OPTIONS);
ERROR LOG:

Is ImageButton Serializable? Can we send ImageButton with Intents or
do we have to extend and ImageButton to implement Parcelable?
Thanks in advance,
