Question

我使用AppCompat主题。迁移到Android Studio 1.1后，背景颜色已从透明变为灰色，更糟糕的是，旋转器显示为白色背景;由于文本颜色也是白色，因此无法读取列表中的项目。

有没有办法获得原始外观，即透明背景，或者至少在哪里必须将微调器背景颜色设置为透明？

编辑：我在屏幕上创建了一个带有2个微调器的基本测试应用程序。第一个微调器在活动布局中声明，第二个微调器来自单独的布局，并在活动布局内膨胀。两个微调器具有相同的配置，但它们的显示方式不同。

我想让第一个微调器（活动布局中的微调器）显示为来自膨胀布局的微调器。

                final TextView textViewLanguage = (TextView) view.findViewById(R.id.textView);
                textViewLanguage.setText(languages.get(position));

                return view;
            }
            @Override
            public View getDropDownView(int position, View convertView, ViewGroup parent)
            {   // This view starts when we click the spinner.
                View row = convertView;
                if(row == null)
                {
                    LayoutInflater inflater = (LayoutInflater) getApplicationContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
