Question

Sorry, for this dumb question…

But I can’t understand how I should write correctly. Here is what I want:

long selectedCartId = cartsSpinner.getSelectedItemId();
if (selectedCartId !=  AdapterView.INVALID_ROW_ID)
     CartDataSource.insertProduct(selectedCartId, prodId, count);

but eclipse generates error for the if-condition:

Incompatible operand types long and Class< INVALID_ROW_ID>

---

INVALID_ROW_ID is declared as this:

public abstract class android.widget.AdapterView extends android.view.ViewGroup {

// <Skipped>

    public static final long INVALID_ROW_ID = -9223372036854775808L;

}

Answer 1

So, the problem was in not cleared project.
