日/夜主题为Android应用 [英] Day/Night theme for android app

问题描述

我有一个应用程序中，我需要实现昼/夜的主题。不幸的是，只需使用样式做主题化没有简单的方法，我需要能够更新：布局背景，按钮选择器，文本颜色，文本大小，图片，图标，动画

I have an app in which I need to implement day / night theme. Unfortunately there is no simple way of making theming by just using styles, I need to be able to update: layout backgrounds, button selectors, text color, text size, images, icons, animations.

这是我所看到的我有两个选择：

From what I see I have 2 options:

1. 有不同的XML布局文件夜/天，所以像 home_day.xml / home_night.xml 。大约有30屏幕的应用程序，所以最终将有60 XML布局。在活动/片段的onCreate，基于当前的小时我可以的setContentView 。这增加了一些XML文件，但避免了增加更多的code。在活动

1. Have different xml layout files for night/day, so something like home_day.xml / home_night.xml. There are around 30 screens in the app, so in the end there will be 60 xml layouts. On activity/fragment onCreate, based on current hour I could setContentView. This adds some more xml files but avoids adding more code in activities

有只有一个昼/夜和布置作业的的onCreate findviewById因为我想主题，根据当前的昼/夜更新自己的属性，每一个项目。这会产生很多额外的code，findviews和应用属性很多意见。

Have only one layout for day/night and on activity's onCreate findviewById for each item I want to theme and update his attributes based on current day/night. This could generate a lot of extra code, findviews and apply attributes for many views.

我的目标为2，但我愿意接受你的任何建议。所以，你会选择，为什么？

I am aiming for for 2. but I am open to any suggestions from you. So, what would you choose and why ?

推荐答案

其实这似乎可以用主题来形容自绘区域为好。看看：<一href="http://stackoverflow.com/questions/13302317/how-to-switch-between-night-mode-and-day-mode-themes">How到夜晚模式和白天模式主题之间进行切换。您可以通过使用样式块创建你的主题，然后在你的XML布局中，可以通过使用指定的东西在你的主题？ATTR。那么你应该能够调用setTheme（R.styles.DAY_THEME）的下一个活动，一切都应该被更新。

Actually it seems you can use themes to describe custom drawables as well. Take a look at: How to switch between night-mode and day-mode themes. You create your themes by using a style block and then in your xml layout you specify something in your theme by using ?attr. Then you should be able to call setTheme(R.styles.DAY_THEME) on the next activity and everything should be updated.
