Question

I want to add the value like ArrayList<HashMap<String, Object>> to intent, and pass on Activity through broadc. The code like this:

ArrayList<HashMap<String, Object>> listItem = new ArrayList<HashMap<String, Object>>();
intent1.putParcelableArrayListExtra("listItem", listItem);

But it has the error:

The method putParcelableArrayListExtra(String, ArrayList<? extends Parcelable>) in the type Intent is not applicable for the arguments (String, ArrayList<HashMap<String,Object>>)

How to use putParcelableArrayListExtra specific? Through realizing Parcelable interface, can it return the ArrayList < HashMap < String, Object > > Object?

Answer 1

Since ArrayList implements Serializable, you don’t have to do anything special to feed it to

Just Use Intent.putExtra() to put the values and use getSerializableExtra() to get the arraylist back to next activity.
