 spinner.setRotation(-90);

But this only rotates the spinner view, not the dropdown. As shown in the picture below. How do I rotate the popup also?

You will need to create a custom adapter for your meter.

Next on your getView, make sure you rotate the parent that is receiving it.

Adapter example:



public class AdapterTest extends ArrayAdapter<String> {


    public AdapterTest(Context context, int resource, List<String> objects) {
        super(context, resource, objects);
    }

    @Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        return getView(position, convertView, parent);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        View v = LayoutInflater.from(getContext()).inflate(R.layout.row_spinner, parent, false);
        if (parent.getRotation() == 0 && parent instanceof ListView) {
             parent.setRotation(-90);
        }
        return v;
    }
}

Result:
