将简单多项选择微调器转换为自定义多项选择微调器

Question

我创建了一个多选微调器示例。它工作正常。但现在我想自定义Spinner行。我不知道如何改变

new ArrayAdapter<String>(context, android.R.layout.simple_spinner_item)

我需要定制：

• 背景颜色
• 复选框背景
• 文字颜色

我该怎么办？非常感谢

                         android.R.layout.simple_list_item_multiple_choice){
                    @Override
