Serializable不会在意图中发送putExtra

Question

Why is my putExtra in my intent is not working no values are being passed in the intent. All of the values are being present on the listview but when I click an item on the listview when I'm going to the DetailActivity there are no values now. Thanks in advance for the answer.

Try

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    Car selectedCars = carList.get(position);
    Intent in = new Intent(getActivity(), DetailActivity.class);
    in.putExtra("cars2", selectedCars);
    startActivity(in);
}

In other Activity :

final Car Cars = getIntent().getSerializableExtra("cars2");
