when I use just TextView in the Second xml it worked well But I need to add card View as a container to this TextView?

Answer 1

If you are using an ArrayAdapter and you have an edited layout (as you have), you should to use the constructor with the TextView id.

You are calling the construtor with wrong arguments, so change all your implementation to this:

YourAdapter:

public GooglePlacesAutocompleteAdapter(Context context, int layoutId, int textViewResourceId) {
        super(context, layout, textViewResourceId);
        this.context = context;
    }

YourActivity:

dataAdapter = new GooglePlacesAutocompleteAdapter(this, R.layout.adapter_google_places_autocomplete, R.id.textView);
