java.lang.UnsupportedOperationException:无法将索引5处的值转换为color:type = 0x5

Question

更新到Android Studio 3 RC1(Gradle4,Android Gradle插件3 RC2)后,我的应用程序崩溃了.

This is the error I am having:
java.lang.RuntimeException: Unable to start activity ComponentInfo{*****}:

更新前我没有遇到这个问题(Android Studio2).它也在github上描述,但没有答案.

Answer 1

更改
compile 'com.viewpagerindicator:library:2.4.1@aar'

至
compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'

它会工作的.该库存在问题.

Answer 2

我的项目使用android gradle plugin 3.0和compileSdk 27​​.我无法使用compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'此线程中建议的解决方案()使用此设置.

它抱怨ViewPager#removeOnPageChangeListener在支持库的第24版中添加了不存在的方法.我认为这与图书馆直接烘焙了android-support-v4.jar这一事实有关.

我不想浏览所有的xml文件并以编程方式设置属性,因此我最终创建了一个使用gradle构建库的fork,并将compileSdk/minSdk/support-v4更新为更现代的版本.

你可以在这里找到这个项目https://github.com/splatte/ViewPagerIndicator

要在项目中使用它,请从jitpack中获取它,如下所示:

allprojects {
    repositories {
      maven { url "https://jitpack.io" }
    }
}

然后:

dependencies {
    implementation 'com.github.splatte:ViewPagerIndicator:3.0.0'
}

(必须有另一个项目在ViewPagerIndicator拥有的4.300分支的海洋中执行此操作,但我不知道如何找到它.)

Answer 3

compile 'com.github.JakeWharton:ViewPagerIndicator:2.4.1'使用jitpack.ioandroid gradle插件3.0对我没用.

相反,我必须以编程方式设置我之前在xml布局中使用cpi:(或app:)属性设置的所有视图属性.

例

<com.viewpagerindicator.CirclePageIndicator
    cpi:fillColor="@color/azure"
    cpi:pageColor="@color/white"
    cpi:radius="4dp"
    cpi:snap="true"
    cpi:strokeWidth="0dp" />

我删除了所有cpi:属性并以编程方式设置它们:

circlePageIndicator.setFillColor(ContextCompat.getColor(getContext(), R.color.azure));
circlePageIndicator.setPageColor(ContextCompat.getColor(getContext(), R.color.white));
circlePageIndicator.setRadius((int) (4 * Resources.getSystem().getDisplayMetrics().density));
circlePageIndicator.setSnap(true);
circlePageIndicator.setStrokeWidth(0);

Answer 4

我找到jitpack.io了最简单的方法：

allprojects {
    repositories {
      maven { url "https://jitpack.io" }
    }
}

进而：

dependencies {
  implementation ('com.github.JakeWharton:ViewPagerIndicator:2.4.1'){
    exclude module: 'support-v4'
  }
}

请注意，有两个版本的 support-v4 库破坏了它，直到我排除了其中一个。
