创建自定义样式崩溃的应用程序 [英] Creating custom style crashes app

问题描述

我建立我的应用程序，以便它可以从多个主题中受益。

I am building my app so that it can benefit from multiple themes.

我已经得到了我想要的添加自定义项目如舞台

I have got to the stage where I want to add custom items e.g.

<style name="My.Theme.Default">
...
    <item name="borderColorDialog">@color/red</item>
...
</style>

<style name="My.Theme.Blue">
...
    <item name="borderColorDialog">@color/blue</item>
...
</style>

所以，我已经添加属性 borderColorDialog 来我的ATTR文件，如下所示：

So I've added the attribute borderColorDialog to my attr file as follows:

<attr name="borderColorDialog" format="color" />

现在我想对它进行测试。我有一个绘制如下：

Now I want to test it. I have a drawable as follows:

<?xml version="1.0" encoding="utf-8"?>
<layer-list 
    xmlns:android="http://schemas.android.com/apk/res/android" >

    <item>

        <shape 
            android:shape="rectangle" >

            <solid 
                android:color="?borderColorDialog" />

        </shape>

    </item> 

    <item
        android:bottom="2dp">

        <shape 
            android:shape="rectangle" >

            <solid 
                android:color="@color/black" />

        </shape>

    </item>
</layer-list>

？

这一切似乎在逻辑上的声音给我，但是 borderColorDialog 引用崩溃模拟器：

This all appears logically sound to me, however the ?borderColorDialog reference crashes the emulator:

该错误的推移而上。基本上指的是对XML。

The error goes on and on. Basically refering to the XML.

将其返回到 @色/红色工作正常。

我该如何解决这个问题？

How can I fix this?

推荐答案

安卓不允许在我的经验引用一个颜色在绘制的属性。我解决了这个问题，一种解决方法创建每个主题一个形状。 我张贴的说明作为一个答案，一个previous的问题在这里：

Android doesn't allow in my experience to reference a color with an attribute in a drawable. I resolved the problem with a workaround creating one shape per theme. I posted a description as an answer to a previous question here:
