Android Studio 中的颜色预览

Question

Is there a way to see the color preview of integer variables that defined as ARGB color in the left gutter of the Editor Window .有没有办法在编辑器窗口的左装订线中查看定义为 ARGB 颜色的integer variables的color preview 。
I mean something like the colors preview that registered as resource.我的意思是类似于注册为资源的颜色预览。

Here's a photoshopped screenshot which shows exactly what I mean.这是一个经过Photoshop处理的屏幕截图，它准确地显示了我的意思。

Answer 1

It's only possible for the colors registered as resource (by the developer as in colors.xml or exists as some Android's resource).仅可能将颜色注册为资源（由开发人员在colors.xml 中注册或作为某些Android 资源存在）。

Is there an easy way to see a color in Android Studio? 有没有一种简单的方法可以在 Android Studio 中查看颜色？

Answer 2

In the case you know all your colours beforehand, import all of them inside the colors.xml file and then each time you use a colour, it will always be displayed on the left.如果您事先知道所有颜色，请将所有颜色导入到colors.xml文件中，然后每次使用颜色时，它都会显示在左侧。 The code will look like this:代码如下所示：

public static void obsidian(ucTheme theme) {
    theme.background_color = R.color.obsidian;
    theme.id = 1000;
}

And the final result will be this:最终结果将是这样的：

Answer 3

It's not possible for int ARGB values, because the IDE can't understand that they're colors, they might be just numbers! int ARGB 值不可能，因为 IDE 无法理解它们是颜色，它们可能只是数字！ Instead, it can show the color preview in the gutter when you're referring to a resource because, parsing R.color.yourColor , the IDE understands that it's a color by the qualifier R.color rather than R.dimen or something.相反，当您引用资源时，它可以在装订线中显示颜色预览，因为在解析R.color.yourColor ，IDE 通过限定符R.color而不是R.dimen或其他东西理解它是一种颜色。
Alternatively, you can look at here to write a plugin for Android Studio which can help you get the desired result.或者，您可以查看此处为 Android Studio 编写一个插件，它可以帮助您获得所需的结果。

Answer 4

show AndroidStudio colors.xml with javascript使用 javascript 显示 AndroidStudio colors.xml

I made a single scriptfile.html , [with all javascript in file includet] to see the color preview of integer variables from colors.xml from AndroidStudio.我制作了一个 scriptfile.html ，[包含文件中的所有 javascript] 来查看来自 AndroidStudio 的 colors.xml 整数变量的颜色预览。

I paste the colors.xml in one << div >> in the scriptfile id="filexml" , parse xml and make sam << div >> with: color |我将 colors.xml 粘贴到脚本文件 id="filexml" 中的一个 << div >> 中，解析 xml 并使 sam << div >> 使用：color | hex |十六进制 | name姓名
