       listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override

           }
       });
    }
}

Answer 1

Modify your State class to have another member Class activityClass; which is a reference to the Activity class name for that State and add those States like following:

stateNames.add(new State("Assam", "Dispur", Assam.class));
stateNames.add(new State("Bihar", "Patna", Bihar.class));
...

Now, change your listener like following

listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        Intent intent = new Intent(MainActivity.this, stateNames.get(position).activityClass);
        startActivity(intent);
    }
});

This will launch your preferred Activity for that State.
