Answer 1

The layout for TextView that is displayed in your Spinner comes from your SpinnerAdapter, which provides 2 methods:

• getView(position, convertView, parent): returns View for collapsed state, you can override this to return different layouts for different selected item
• getDropdownView(position, convertView, parent): return View for each dropdown item in expanded state (after you click Spinner to open popup/dialog for selection)

In your case you should override your SpinnerAdapter.getView(position, convertView, parent) and inflate the layout with padding/spacing of your choice.

For example:

spinner.setAdapter(new MyAdapter());

MyAdapter.java

class MyAdapter implements SpinnerAdapter {
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(parent.getContext()).inflate(R.layout.spinner_item, parent, false);
        }
        // bind your data here
        return convertView;
    }
    // other implementation
}

res/layout/spinner_item.xml

You can also conveniently use one of the framework provided SpinnerAdapter indirect subclasses (ArrayAdapter, BaseAdapter, CursorAdapter, ResourceCursorAdapter, SimpleAdapter, SimpleCursorAdapter, ThemedSpinnerAdapter), just make sure to supply the correct layout that would be used by getView() method.
