充气课时出错？

Question

我将项目从Eclipse迁移到Android Studio。在我的项目中，我添加了this library。 我已将库添加为gradle文件中的依赖项。我可以从我的班级导入库。
但它显示了这个

android.view.InflateException: Binary XML file line #8: Error inflating class com.digitalaria.gama.wheel.Wheel

运行应用程序时

。

注意 - 从Eclipse运行它时工作正常。

gradle这个

apply plugin: 'android'

dependencies {
    //    compile fileTree(dir: 'libs', include: '*.jar')
    compile project(':RemoteIt Protocol')
    compile project(':android-support-v7-appcompat')
    compile files('libs/gama_wheel_v1.0.jar')
    compile files('libs/PayPalAndroidSDK.jar')
}

android {
    compileSdkVersion 19
    buildToolsVersion "20.0.0"

    sourceSets {
        main {
            manifest.srcFile 'AndroidManifest.xml'
            java.srcDirs = ['src']
            resources.srcDirs = ['src']
            aidl.srcDirs = ['src']
            renderscript.srcDirs = ['src']
            res.srcDirs = ['res']
            assets.srcDirs = ['assets']
        }

        // Move the tests to tests/java, tests/res, etc...
        instrumentTest.setRoot('tests')
            debug.setRoot('build-types/debug')
        release.setRoot('build-types/release')
    }
}

Answer 1

相关例外：

Caused by: java.lang.UnsupportedOperationException: Can't convert to integer: type=0x3
at android.content.res.TypedArray.getInteger(TypedArray.java:368)
at com.digitalaria.gama.wheel.WheelBehavior.<init>(WheelBehavior.java:117)

WheelBehavior.java，第117行

setWheelDiameter(arr.getInteger(R.styleable.Wheel_wheel_diameter, Configuration.DEFAULT_WHEEL_DIAMETER));

以下是可设置的属性：

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <declare-styleable name="Wheel">
        <attr name="wheel_rotation_duration" format="integer"/> <!-- default:400 -->
        <attr name="wheel_diameter" format="integer"/> <!-- default:250 -->
        <attr name="items" format="integer"/>
        <attr name="item_selected_index" format="integer"/>
    </declare-styleable>
</resources>

必须在项目的某个地方定义

wheel_diameter，而不是在其中包含整数。这就是崩溃的原因。但根据你的布局，它不是。尝试对字符串wheel_diameter

进行全局搜索

Answer 2

我认为我的回答是狂野的，但您可以尝试设置layout_gravity="center"或layout_gravity="center_horizontal"因为我认为图书馆的创建者会尝试获取此属性。

Answer 3

尝试替换此代码：

compile files('libs/gama_wheel_v1.0.jar')
compile files('libs/PayPalAndroidSDK.jar')

使用此代码：

compile fileTree(dir: 'libs', include: '*.jar')

我认为你需要研究这个。不确定Wheel是否是您制作或下载的内容，但它的设置似乎有问题。
