Question

I have several spinners that I have created a custom ArrayAdapter for so I can change the drop down menu look. I want to manipulate the view depending on what spinner the dropdown belongs to. I thought I would be able to do something like parent.getTag() but it is returning null.

The custom array adapter looks like:

class BackgroundColorAdapter extends ArrayAdapter<String> {
    BackgroundColorAdapter() {
        super(SettingsActivity.this, R.layout.settings_spinner_item, R.id.item_text, textColors);
    }

    public View getDropDownView (int position, View convertView, ViewGroup parent){
        View row=super.getView(position, convertView, parent);
        if(parent.getTag().equals("background"){
            //Do custom stuff here
        }
        return(row);
    }
}

and I’m setting the tag:

settingsSpinner.setTag("bg_color_spinner");
settingsSpinner.setAdapter(new BackgroundColorAdapter());

I think I’m confused how the view hierarchy works but it seems logical that the parent of the spinner drop down would be the spinner. Anyone know how I can find out what spinner the drop down belongs to in getDropDownView?

edit: made the settingsSpinner a single spinner instead of an array of spinners to make it less confusing

Eventually got this to work, here is the code for example that changes the text font for each item in the drop down.

class TextSizeAdapter extends ArrayAdapter<String> {

        TextSizeAdapter() {
            super(SettingsActivity.this, R.layout.settings_spinner_item, R.id.item_text, textSizes);
        }

        public View getDropDownView (int position, View convertView, ViewGroup parent){

            View row=super.getView(position, convertView, parent);
            TextView text = (TextView)row.findViewById(R.id.item_text);
            text.setTextSize(TypedValue.COMPLEX_UNIT_PX,appState.FONTSIZES[position]);
            RadioButton radio = (RadioButton)row.findViewById(R.id.item_radio);
            if(settingsSpinners[2].getSelectedItemPosition() == position){
                radio.setChecked(true);
            }else{
                radio.setChecked(false);
            }

            return(row);
        }
    }
