【Android】Spinner组件如何去除Padding左边距

Spinner左边有边距是因为item布局里自带了边距，所以只需要在getView里获取到item布局然后移除掉边距即可，字体大小也是如此。

@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;
}
