如何让用户选择Android中的列表视图主题？ [英] How to allow users to choose themes in android list view?

问题描述

我有两个标签，标题和副标题列表视图。我想有深色和浅色背景的用户选项。标题有textAppearanceMedium和字幕都有textAppearanceSmall。我想要的风格，MyTheme.Dark有白色文字和MyTheme.Light有黑色文本。有没有办法来定义多个textAppearance属性为同一部件TextView的？

 ＆LT;样式名称=MyTheme.Dark＆GT;
    ＆LT;项目名称=机器人：windowBackground＆GT; @彩色/黑白LT; /项目＆GT;
    ＆LT;项目名称=机器人：colorBackground＆GT; @彩色/黑白LT; /项目＆GT;
    ＆LT;项目名称=机器人：背景＆GT; @彩色/黑白LT; /项目＆GT;
    ＆LT;项目名称=机器人：分＆GT; @色/白＆LT; /项目＆GT;
        --cannot把textAppearance在这里，因为它是标题和副标题不同
    ＆LT; /风格＆GT;
 

解决方案

我认为最好的办法是有不同的颜色和主题不同的布局XML。加载基于用户选择的布局XML。我不喜欢这个，但我还没有发现任何的替代品。

I have a listview with two labels, title and subtitle. I want to have dark and light background as user options. Title has textAppearanceMedium and subtitle has textAppearanceSmall. I want the style, MyTheme.Dark to have white color text and MyTheme.Light to have black color text. Is there a way to define multiple textAppearance attribute for the same TextView widget?

<style name="MyTheme.Dark">
    <item name="android:windowBackground">@color/black</item>
    <item name="android:colorBackground">@color/black</item>
    <item name="android:background">@color/black</item>
    <item name="android:divider">@color/white</item>
        --cannot put textAppearance here since it is different for title and subtitle
    </style>

解决方案

I think best way is to have different layout xml for different colors and themes. Load the layout xml based on user choice. I do not like this but I have not found any alternatives.
