在androidxml中重新使用自定义格式

考虑定义为的自定义xml枚举

<attr name="myProperty">
    <enum name="None" value="0"/>
    <enum name="One" value="1"/>
    <enum name="Two" value="2"/>
    <enum name="Three" value="3"/>
    <enum name="Four" value="4"/>
    <enum name="Five" value="5"/>
    <enum name="Six" value="6"/>
    <enum name="Seven" value="7"/>
    <enum name="Eight" value="8"/>
    <enum name="Nine" value="9"/>
    <enum name="Ten" value="10"/>
</attr>

我正在使用此枚举，如下所示

<declare-styleable name="MyUnrelatedControl">
    <attr name="myProperty" />
</declare-stylable>

但问题是，假设我有两个相同格式的属性（自定义枚举），如何实现这一点。比如说

<declare-styleable name="MyUnrelatedControl">
    <attr name="unrelatedControl1" /> <!-- format=myProperty -->
    <attr name="unrelatedControl2" /> <!-- format=myProperty -->
</declare-stylable>

像左边距、右边距、上边距、下边距一样，都采用相同的格式

维度

。类似地，我想定义一种格式，并将其用于同一个declare stylable中的不同属性

谢谢你的帮助。

没有解决办法。原因是这样的枚举定义不应该被重用。对于每个属性，都需要定义一组单独的可能值。当你观察机器人时，这是显而易见的：

所以看来你想做的事情是不可能的

我怀疑是否存在解决办法。看看它在框架中的使用方式。枚举在

layout\u width

和

layout\u height

定义中重复。你可以从中看出，我怀疑是否存在解决方案。看看它在框架中的使用方式。枚举在

layout\u width

和

layout\u height

定义中重复。你可以在这张照片上看到
