获取颜色值HEX代码android

【问题标题】：Getting color value HEX code android获取颜色值HEX代码android

【问题描述】：

嘿，我正在关注 thenewboston 的 Android 学习系列。我在这部分：http://www.youtube.com/watch?feature=player_embedded&v=QjQg8NkHGbw

现在，我想做的是将一些基本颜色，如红色、绿色等保存在某处（在代码或文件中）并分配它们的十六进制代码。

如果用户在“edittext”中输入“red”，那么我想将“red”的值存储为“#FF0000”（就像 C++ 中的#define），等等蓝色、绿色等。

我已经熟悉 C++ 中的文件处理，但这似乎完全不同。

我不知道如何存储本身就是字符串的字符串的值。

    【解决方案1】：

    在你的项目的 values 文件夹中添加一个名为 color.xml 的文件，在其中添加以下内容

    <?xml version="1.0" encoding="utf-8"?>
<resources>
 <color name="white">#FFFFFF</color>
 <color name="yellow">#FFFF00</color>
 <color name="fuchsia">#FF00FF</color>
 <color name="red">#FF0000</color>
 <color name="silver">#C0C0C0</color>
 <color name="gray">#808080</color>
 <color name="olive">#808000</color>
 <color name="purple">#800080</color>
 <color name="maroon">#800000</color>
 <color name="aqua">#00FFFF</color>
 <color name="lime">#00FF00</color>

    【讨论】：

    • 谢谢，但我想知道如何将字符串更改为 int。例如，如果用户输入 "Red" ，我可以做 tvColor.setTextColor(getResources().getColor(R.color.Red)); （但我需要使用开关和大小写，它会很长）有没有像 String id = "R.color.";字符串 id = "R.id." + etUser.getText(); tvColor.setTextColor(getResources().getColor(id));
    • @KartikSharma 我建议为用户提供通过微调器选择颜色的选项，然后您不需要编写开关盒您可以使用“R.id.”++ etUser.getText();
