Android - Issue with AutoCompleteTextView element, setOnItemClickListener not working

Question

I have the following Activity code which ref. the R.layout.pool_details_new_layout (code below)

The Adapter ref. the number_of_players_dropdown_layout (code below)

Everything works fine, the view loads the AutoCompleteTextView dropdown box populates and when i click on it is shows all the entires in it

BUT

when i select an item, I am expecting for the numPlayersSelected.setOnItemClickListener to execute and log to the logcat and show a toast on the screen but nothing happens!?

Does anyone know what i am missing!?

Activity code:

public class PoolDetailsActivity extends AppCompatActivity {

    ArrayAdapter<SkuItem> numPlayersAdapter;
    private AutoCompleteTextView numPlayersSelected;
    public static Activity activity = null;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
    
        setContentView(R.layout.pool_details_new_layout);
       
        activity = this;

        numPlayersSelected = (AutoCompleteTextView) findViewById(R.id.numOfPlayersAddSelected);
                    
        numPlayersAdapter = new IAPSkuAdapter(activity, R.layout.number_of_players_dropdown_layout, numPlayersArray);

        numPlayersSelected.setAdapter(numPlayersAdapter);

        // NOT WORKING!?   <-------------------------------------
        numPlayersSelected.setOnItemClickListener(new AdapterView.OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {

                String selectedItemText = (String) parent.getItemAtPosition(position);

                Toast.makeText(getBaseContext(),selectedItemText + " selected!", Toast.LENGTH_LONG).show();
                Log.e(TAG, "<< SELECTED >> : " + selectedItemText);

            }

        }
                    
    }

}

-------------- UPDATE ----------------

Adapter Class Code:

public class IAPSkuAdapter extends ArrayAdapter<SkuItem> {

    public IAPSkuAdapter(@NonNull Context context, int resource, @NonNull List<SkuItem> skuItemList) {
  
        super(context, resource, skuItemList);

    }

    @NonNull
    @Override
    public View getView(int position, @Nullable View convertView, @NonNull ViewGroup parent) {
        
        if (convertView == null) {

            convertView = LayoutInflater.from(getContext()).inflate(R.layout.number_of_players_dropdown_layout, parent, false);

        }

        TextView skuTitle = convertView.findViewById(R.id.skuTitle);

        TextView skuPrice = convertView.findViewById(R.id.skuPrice);

        SkuItem skuItem = getItem(position);

        skuTitle.setText(skuItem.getSkuTitle());
    
        skuPrice.setText(skuItem.getSkuPrice());
    

        return convertView;

    }

}

Answer 1

Here are 2 things you could try:

1. You could try to setup the clickListener() Method in the Adapter for each item:

convertView.setOnClickListener(v -> { //Your code here }); In this example we assume that the click method should be triggerd when the convertView is pressed.

2. Also try to make sure that the array numPlayersArray isn't empty, when the ClickListener gets assigned.

Please let me know if it helped.
