从偏好中移除涟漪效应

Question

我想要一个可点击但隐藏的偏好，没有涟漪效应。

我尝试在 XML 中添加按钮、创建自定义首选项和禁用某些东西，但涟漪效应仍然存在。

如何创建可单击但隐藏且没有涟漪效应的首选项？

        v.setBackgroundColor(Color.TRANSPARENT);
        v.setAlpha(0);

        return v;
    }
}

我最终创建了一个带有透明Image的LinearLayout ，然后我使用LinearLayout作为我想要隐藏的首选项的布局。

        LayoutInflater li = (LayoutInflater)v.getContext().getSystemService( Context.LAYOUT_INFLATER_SERVICE );

        return li.inflate(R.layout.hidden_preference, parent, false);

    @Override
