If you are using custom adapter, then try setting padding in `getView()` :
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
view.setPadding(0, view.getPaddingTop(), view.getPaddingRight(), view.getPaddingBottom());
return view;
}
In your SpinnerAdapter:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View view = super.getView(position, convertView, parent);
view.setPadding(0, view.getPaddingTop(), view.getPaddingRight(), view.getPaddingBottom());
return view;
}
