错误：在<declare-styleable>中 - 无法找到属性

时间：2017-03-19 17:43:59

标签： android gradle attributes

我在尝试构建项目时遇到了缺少属性的Gradle错误;

Error:In <declare-styleable> ReflowText, unable to find attribute maxDuration

和

Error:In <declare-styleable> ReflowText, unable to find attribute velocity

我刚尝试在我的项目中实现ReflowText。 ReflowText课程已经复制＆amp;从上面的链接粘贴没有任何更改（包名称除外），我已经复制了相关的必需属性;

res/values/attrs_reflow_text.xml     

<resources>

    <declare-styleable name="ReflowText">
        <attr name="velocity" />
        <attr name="minDuration" />
        <attr name="maxDuration" />
        <attr name="staggerDelay" format="integer" />
        <attr name="freezeFrame" format="boolean" />
    </declare-styleable>

</resources>

我无法理解为什么会出现构建错误。我已经查看了其他各种类似错误的SO问题，但没有一个问题似乎解决了我的问题;

我的完整Gradle控制台输出是; 

Executing tasks: [:app:generateDebugSources, :app:generateDebugAndroidTestSources, :app:mockableAndroidJar, :app:prepareDebugUnitTestDependencies, :app:compileDebugSources, :app:compileDebugAndroidTestSources, :app:compileDebugUnitTestSources]

Configuration on demand is an incubating feature.
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory.  It is currently set to C:\Users\Jonny Wright\AppData\Local\Android\Sdk\ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.

答案 0 :(得分：0)

<attr>标记需要两个属性：name和format。

developer.android.com中没有对此进行充分的文档说明，但是您可以在developer.android.com/training/custom-views/create-view中对其略作了解。

您需要对velocity，minDuration和maxDuration拥有完整的出处：

    ...
    <attr name="velocity" format="integer" />
    <attr name="minDuration" format="integer" />
    <attr name="maxDuration" format="integer" />
    ...

检查integer是否为所需的格式。其他有效值包括float，string，boolean，color，dimension，fraction，enum，{{1} }和flag。
