在attrs.xml自定义视图同名属性 [英] Same-named attributes in attrs.xml for custom view

问题描述

我在写这分享一些同名属性的一些自定义视图。在各自的＆LT;申报，设置样式＆GT; 在 attrs.xml 部分我想使用相同的名称属性：

I'm writing a few custom views which share some same-named attributes. In their respective <declare-styleable> section in attrs.xml I'd like to use the same names for attributes:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="MyView1">
        <attr name="myattr1" format="string" />
        <attr name="myattr2" format="dimension" />
        ...
    </declare-styleable>

    <declare-styleable name="MyView2">
        <attr name="myattr1" format="string" />
        <attr name="myattr2" format="dimension" />
        ...
    </declare-styleable>
</resources>

我收到一个错误，指出 myattr1 和 myattr2 已经定义。我发现，我应该省略格式属性 myattr1 和 myattr2 在 MyView2 ，但如果我这样做，我得到了下面的错误在控制台：

I'm getting an error saying that myattr1 and myattr2 are already defined. I found that I should omit the format attribute for myattr1 and myattr2 in MyView2, but if I do that, I obtain the following error in the console:

[2010-12-13 23:53:11 - MyProject] ERROR: In <declare-styleable> MyView2, unable to find attribute 

有没有一种方法，我可以做到这一点，也许某种命名空间（只是猜测）？

Is there a way I could accomplish this, maybe some sort of namespacing (just guessing)?

感谢您的帮助;）

推荐答案

只需提取这两种观点共同属性，并直接将它们添加为＆LT儿童;资源＆GT; 节点：

SOLVED!

Simply extract common attributes from both views and add them directly as children of the <resources> node:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <attr name="myattr1" format="string" />
    <attr name="myattr2" format="dimension" />

    <declare-styleable name="MyView1">
        <attr name="myattr1" />
        <attr name="myattr2" />
        ...
    </declare-styleable>

    <declare-styleable name="MyView2">
        <attr name="myattr1" />
        <attr name="myattr2" />
        ...
    </declare-styleable>
</resources>
