            </TableRow>

    </LinearLayout>

</ScrollView>

and here is my add_phone_row.xml 

<?xml version="1.0" encoding="utf-8"?>
<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" android:layout_height="match_parent" >

    <EditText android:id="@+id/etContactPhone"
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_weight="1" android:inputType="phone" />

    <Spinner android:id="@+id/sContactPhoneType"
        android:layout_width="wrap_content" android:layout_height="wrap_content" />

</TableRow>

I am creating Spinner and EditText dynamically in bellow fucntion

    if (fieldType.equals("phone")) {
            // for phone number code is 80
            phoneNumbersIdStarter++;
            View view = layoutInflater.inflate(R.layout.add_phone_row, null);
            EditText phoneNumberField = (EditText) view.findViewById(R.id.etContactPhone);
            Spinner phoneTypeSpinner = (Spinner) view.findViewById(R.id.sContactPhoneType);
            Log.d(TAG, "spinner id = " + phoneTypeSpinner.getId());
            phoneNumberField.setId(8084+phoneNumbersIdStarter);
            phoneTypeSpinner.setId(8083+phoneNumbersIdStarter);
            Log.d("Spinner Created", "Spinner Id = " + phoneTypeSpinner.getId());
            setSpinnerValues(phoneTypeSpinner, "phone");
            phoneFiledsCont.addView(view);
        }

and getting their values like below lines 

    EditText phoneNumberField = (EditText) findViewById(8084+phoneNumbersIdStarter);
    Spinner phoneNumberSpinner = (Spinner) findViewById(8083+phoneNumbersIdStarter);

and each time i add these fields also add 1 in phoneNumbersIdStarter

if I comment the following line in my code it runs great

    Spinner phoneNumberSpinner = (Spinner) findViewById(8083+phoneNumbersIdStarter);

    Basically, you're trying to cast an EditText to a Spinner. Perhaps you are looking up the wrong view with findViewById Commented Nov 20, 2014 at 19:54
  • No I am not casting an EditText to a Spinner. if you check my code I have a function addTextField and i am creating a EditText and a Spinner each time i call that function. But I get this error when i try to access that Spinner in other function. Commented Nov 21, 2014 at 6:48
  • @PiyushGupta I have added xml file as well Commented Nov 21, 2014 at 7:52
  • Why do you implement OnClickListener? Commented Nov 22, 2014 at 16:53
  • @jyoon because i am creating EditText and Spinner on button click Commented Nov 22, 2014 at 16:55

Do you have some specific reason to not access the widgets using R.id.?

I don't think a good idea to use "8083+phoneNumbersIdStarter", because the int id which is generated in class R will change in each compilation, so probably the int 8083+phoneNumbersIdStarter is referring to a widget which is not an EditText.

So, change to something like this:

Spinner phoneNumberSpinner = (Spinner) findViewById(R.id.your_spinner_id);

Yes I do have. I am creating Spinner and EditText in my java class if you check function named as addTextField you will find it out.

I found error by myself. Error was because of id confliction. Because I was adding 1 in phoneNumbersIdStarter on click of Add Phone Button. So my EditText ID starer was 8084+phoneNumbersIdStarter and Spinner ID starter 8083+phoneNumbersIdStarter thats why Spinnner was conflicting with EditText when creating fields second time.

Solved error by changing Spinner ID starter from 8083+phoneNumbersIdStarter to 9083+phoneNumbersIdStarter as shown below now it is working great.

EditText phoneNumberField = (EditText) findViewById(8084+phoneNumbersIdStarter);
Spinner phoneNumberSpinner = (Spinner) findViewById(9083+phoneNumbersIdStarter);
