Passing a List from one Activity to another

android, android-intent, arraylist, listview

Solution

You can pass an `ArrayList<E>` the same way, if the `E` type is `Serializable`.

You would call the `putExtra (String name, Serializable value)` of `Intent` to store, and `getSerializableExtra (String name)` for retrieval.

Example:

ArrayList<String> myList = new ArrayList<String>();
intent.putExtra("mylist", myList);

In the other Activity:

ArrayList<String> myList = (ArrayList<String>) getIntent().getSerializableExtra("mylist");

Please note that serialization can cause performance issues: it takes time, and a lot of objects will be allocated (and thus, have to be garbage collected).

Problem

How to pass Collections like `ArrayList`, etc from one `Activity` to another as we used to pass `Strings`, `int` with help of putExtra method of Intent? Can anyone please help me as i want to pass a `List<String>` from one `Activity` to another?
