Override getDropDownView method in ArrayAdapter and put setSingleLine(false) in post method of view. So when view completly created it wraps the text to appropriate lines.

@Override
    public View getDropDownView(final int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = new TextView(_context);
        }

        TextView item = (TextView) convertView;
        item.setText("asddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd");
        final TextView finalItem = item;
        item.post(new Runnable() {
            @Override
            public void run() {
                finalItem.setSingleLine(false);
            }
        });
        return item;
    }

Try this

<Spinner
    android:id="@+id/spinnerFrom"
    style="@style/Widget.AppCompat.Spinner.Underlined"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
