在 Android 中创建 XML 整数列表

发布于 2024-08-30 07:29:04 字数 391 浏览 3 评论 0原文

我想在 android 项目的 /res 文件夹中创建一个整数列表。但是，我希望这些整数指向 /res/raw 中的资源。例如，我想要这样的东西：

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <integer-array name="built_in_sounds">
            <item>@raw/sound</item>
    </integer-array>
</resources>

但是 id 看起来我不能做到这一点，有什么办法可以做到这一点吗？或者我应该在 java 类中创建列表？

谢谢

I would like to create a list of Integers in the /res folder of an android project. However, I want those integers to point resources in /res/raw. So for example, I would like something like this:

<?xml version="1.0" encoding="utf-8"?>
    <resources>
        <integer-array name="built_in_sounds">
            <item>@raw/sound</item>
    </integer-array>
</resources>

But id doesn't look like I can do that, is there any way to do this? Or should I just create the list in a java class?

Thank you

正确的答案实际上是 TypedArray

文档显示资源列表的示例：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="icons">
        <item>@drawable/home</item>
        <item>@drawable/settings</item>
        <item>@drawable/logout</item>
    </array>
    <array name="colors">
        <item>#FFFF0000</item>
        <item>#FF00FF00</item>
        <item>#FF0000FF</item>
    </array>
</resources>

以及检索值的代码：

Resources res = getResources();
TypedArray icons = res.obtainTypedArray(R.array.icons);
Drawable drawable = icons.getDrawable(0);

TypedArray colors = res.obtainTypedArray(R.array.icons);
int color = colors.getColor(0,0);

And the correct answer is actually, TypedArray

The documentation shows examples of lists of resources:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <array name="icons">
        <item>@drawable/home</item>
        <item>@drawable/settings</item>
        <item>@drawable/logout</item>
    </array>
    <array name="colors">
        <item>#FFFF0000</item>
        <item>#FF00FF00</item>
        <item>#FF0000FF</item>
    </array>
</resources>

And the code to retrieve the values:

Resources res = getResources();
TypedArray icons = res.obtainTypedArray(R.array.icons);
Drawable drawable = icons.getDrawable(0);

TypedArray colors = res.obtainTypedArray(R.array.icons);
int color = colors.getColor(0,0);
