Answer 1

Short answer for fast need

1. Implement your Class to Serializable.

If you have any inner Classes don't forget to implement them to Serializable too!!

public class SportsData implements  Serializable
public class Sport implements  Serializable

List clickedObj;

2. Put your object into Intent

 Intent intent = new Intent(SportsAct.this, SportSubAct.class);
            intent.putExtra("sport", clickedObj);
            startActivity(intent);

3. And receive your object in the other Activity Class

Intent intent = getIntent();
    Sport cust = (Sport) intent.getSerializableExtra("sport");
