From you post I understand you have a spinner and an imageview next to it and you want to expand the spinner when the user clicks on the imageview. You can call the performClick() method of the spinner view inside your imageview's listener:

Spinner yourSpinnerView = (Spinner) view.findViewById(R.id.yourSpinnerView);
dropDownArrow2 = (ImageView) view.findViewById(R.id.dropDownImage2);
dropDownArrow2.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        yourSpinnerView.performClick();
    }
});

If you want to populate the spinner with data you can copy the code from the developer's website here . Not sure what you mean about adding data to the imageview.
