Android adapter.getItem(position).getItemId() not working (The method getId() is undefined for the type Object)

android, android-adapter, android-listview, listviewitem

Solution

You must cast the `getItem(position)` return value to a `Countries` object.

Change this:

    intent.putExtra("countryId", adapter.getItem(position).getId());

To this:

    Countries countries = (Countries)adapter.getItem(position);
    intent.putExtra("countryId", countries.getId());

Update:

Actually, after reading @Tushar's comment, I think you should make `names` a `VisaAdapter` instead of an `ArrayList<Countries>()`. Then, your original line of code, above, should work as-is.

Problem

I have a listview and i am populating the data to the list view form DB using custom adapter. Its working fine, but when i click on the list item, i want to get the ID of the item which is clicked to pass it on to the next activity to do some stuff. But when i click on list item, i am not able to get the ID. Any idea why is this happening? my list listener: ``` list.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> a, View view, int position, long id) { Intent intent = new Intent(MainActivity.this, CountryActivity.class); intent.putExtra("countryId", adapter.getItem(position).getId());//here i am getting error saying //The method getId() is undefined for the type Object. startActivity(intent); } }); ``` But i have defined my countries.java (POJO) for type specification ``` public class Countries { Integer id; String countryName = "", countryIcon = ""; public Countries(Integer id, String countryName, String countryIcon) { this.id = id; this.countryName = countryName; this.countryIcon = countryIcon; } public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getCountryName() { return countryName; } public void setCountryName(String countryName) { this.countryName = countryName; } public String getCountryIcon() { return countryIcon; } public void setCountryIcon(String countryIcon) { this.countryIcon = countryIcon; } } ``` i am fetching data out of cursor obj (visas) from the below code: ``` names = new ArrayList<Countries>(); do { country = new Countries(Integer.parseInt(visas.getString(0)), visas.getString(1), visas.getString(2)); // Log.d("VISA", visas.getString(0)); names.add(country); } while (visas.moveToNext()); ``` here is my adapter code: ``` public class VisaAdapter extends ArrayAdapter<Countries> { private final Context context; private final ArrayList<Countries> values; Resources resc = getContext().getResources(); public VisaAdapter(Context context, ArrayList<Countries> values) { super(context, R.layout.list_item, values); this.context = context; this.values = values; } @Override public Countries getItem(int position) { return values.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context .getSystemService(Context.LAYOUT_INFLATER_SERVICE); View rowView = inflater.inflate(R.layout.list_item, parent, false); TextView textView = (TextView) rowView.findViewById(R.id.label); ImageView imageView = (ImageView) rowView.findViewById(R.id.logo); textView.setText(values.get(position).getCountryName()); // Change icon based on name String icon = values.get(position).getCountryIcon(); int resIcon = resc.getIdentifier(icon, "drawable", "com.m7.visaapp"); rowView.setBackgroundResource(R.drawable.list_view_places_row); imageView.setImageResource(resIcon); return rowView; } } ```
