In my application I have a spinner inside listview, The code below is which i manage the spinner.

Inside the getview() of listview adapter

    addSpinnerValue(mList.get(position).getSchedule());// method to set the ArrayAdapter to spinner
    spinnerSchedule.setOnItemSelectedListener(new OnItemSelectedListener() {

            @Override
            public void onItemSelected(AdapterView<?> arg0, View arg1,
                    int arg2, long arg3) {
                Log.w("onCLick","position"+arg2);

            }

            @Override
            public void onNothingSelected(AdapterView<?> arg0) {
                // TODO Auto-generated method stub

            }
        }); 

  //Method which is setting the spinner Adapter(Outside the getview)
  public void addSpinnerValue(String schedule) {
    ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(Activity_ManageListing.this,R.layout.row_spinner, R.id.textView1, spinnerforlist);
    spinnerSchedule.setAdapter(adapter1); 
  }

When spinner clicks , i got the error as:
