android intent pass object code example

Example 1: pass list to intent in android java

First, make the class of the list implement Serializable.

public class Object implements Serializable{}
Then you can just cast the list to (Serializable). Like so:

List<Object> list = new ArrayList<Object>();
myIntent.putExtra("LIST", (Serializable) list);
And to retrieve the list you do:

Intent i = getIntent();
list = (List<Object>) i.getSerializableExtra("LIST");

Example 2: android pass object to activity

Intent intent = new Intent(fromClass.this,toClass.class).putExtra("myCustomerObj",customerObj);

Example 3: android pass object to activity

Customer customerObjInToClass = getIntent().getExtras().getParcelable("myCustomerObj");
