android - 如何在 Android 上使用 citeproc-java

标签 android rhino

我正在调查 de.undercouch:citeproc-java:2.0.0在我当前的 Android 应用程序中。
我无法识别 ScriptEngine在 Android 上使用 citeproc-java .
我的 Gradle 类似于:-

ext {
    compileSdkVersion = 30
    minSdkVersion = 26
    targetSdkVersion = 30
}

dependencies {

    implementation 'io.apisense:rhino-android:1.1.1'

    implementation 'de.undercouch:citeproc-java:2.0.0'
    implementation 'org.citationstyles:styles:20.11'
    implementation 'org.citationstyles:locales:20.11'

    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.4.10"
}
Citeproc需要 javax.script.ScriptEngineManager这在 Android 平台上不可用，因此我替换为 io.apisense:rhino-android:1.1.1我现在正面临这个异常(exception)......

导致此异常的 citeproc 代码直接取自他们的示例...
private fun what() {

    val citeproc = CSL(MyItemProvider(), "ieee")
    citeproc.setOutputFormat("text")
    citeproc.registerCitationItems("ID-1", "ID-2", "ID-3")

    val s1 = citeproc.makeCitation("ID-1")
    println(s1[0].text)
    //=> [1] (for the "ieee" style)

    //=> [1] (for the "ieee" style)
    val s2 = citeproc.makeCitation("ID-2")
    println(s2[0].text)
    //=> [2]

    //=> [2]
    val bibl = citeproc.makeBibliography()  //EXCEPTION RAISED HERE!!!!!!
    for (entry in bibl.entries) {
        println(entry)
    }

}
我创建了一个 AndroidJUnit 来调查这个问题。
在单步执行代码时，我发现问题是 arrayOutOfBoundsException 访问字符串 []
该数组只有 12 个条目，但索引为 39
如 AS 图像所示
enter image description here

最佳答案

正如我在调试器中看到的值，它在 中显示了 12 个项目。 iCode[] 大批 。
和来自.pc 值 39 是数组索引异常的原因。
正如您的代码 来自.pc 值增加一个条件的前增量，而另一个值增加后增量，每次增加 2。
而您正在使用 continue没有检查总是创建异常的数组的大小。
您应该检查您的条件，因为如果第 39 位的预期值或索引增量不正确，看起来数组确实已正确初始化。
