One option could be letting your custom class implement the Serializable
interface and then you can pass object instances in the intent extra using the putExtra(Serializable..)
variant of the Intent#putExtra()
method.
Actual Code:
In Your Custom Model/Object Class:
public class YourClass implements Serializable {
At other class where using the Custom Model/Class:
//To pass:
intent.putExtra("KEY_NAME", myObject);
myObject is of type “YourClass”.
Then to retrieve from another activity, use getSerializableExtra
get the object using same Key name. And typecast to YourClass is needed:
// To retrieve object in second Activity
myObject = (YourClass) getIntent().getSerializableExtra("KEY_NAME");
Note: Make sure each nested class of your main custom class has implemented Serializable interface to avoid any serialization exceptions. For example:
class MainClass implements Serializable {
public MainClass() {}
public static class ChildClass implements Serializable {
public ChildClass() {}
}
}
