在strings.xml中存储十六进制颜色值

Question

在strings.xml中存储十六进制颜色值

17

我正在尝试将文本的十六进制颜色值存储在strings.xml中，以便所有布局文件都可以引用它（以便能够轻松更改整个项目的所有布局文本），但是我无法引用它。

在我的xml布局中使用android:textColor="#FFFFFF"可以正常工作。然而，在使用android:textColor="@strings/textColor"时，无论包括还是不包括#，都会出现错误。

当我不包含#时，它会要求加上#。当我添加#时，DDMS报告：

07-13 04:35:22.870: ERROR/AndroidRuntime(331): Caused by: android.content.res.Resources$NotFoundException: File #FF0000 from drawable resource ID #0x7f040003: .xml extension required

有人知道如何在布局文件中组合语句吗？例如textColor="#"+"@strings/textColor，然后将字符串设置为"FFFFFF"。

您可以声明显式的颜色资源。按照惯例，这些资源应该放置在res/values/colors.xml文件中：

<resources>
    <color name="my_color">#FFFFFFFF</color>
</resources>

然后在布局文件或其他地方，您可以编写android:textColor="@color/my_color"。

您可以这样做：在values文件夹中定义colors.xml，然后按照以下方式添加颜色值：

<color name="your_color_name">#your_color_value</color>

<?xml version="1.0" encoding="utf-8"?>
<resources>
   <color name="myColor">#000000</color>
</resources>

那么在应用程序中如何引用这个颜色值：

静态的：

android:textColor="@color/myColor"

编码：

TextView1.setTextColor(R.color.myColor);

### 你的代码在 string.xml 文件中 ###

  < color name="textColor">#FFFFFF< /color>

在你的代码中，你声明了颜色名称为"textColor"，我想确认一下，给定的文本颜色名称是内置方法，但你不能覆盖内置方法。

解决你的问题的方法是，你的代码应该像这样：

< color name="text_color">#FFFFFF< /color>

在这种情况下，颜色的名称不是内置方法，您也没有遇到任何运行时错误。

谢谢。

您需要在xml中创建一组样式（通常在res/values/styles.xml中）

<color name="gray">#eaeaea</color>
<color name="titlebackgroundcolor">#00abd7</color>
<color name="titlecolor">#666666</color>

在布局文件中，您可以调用颜色或样式：

android:textColor="@color/titlecolor"

以下是一些示例：
