java - Android Studio 抛出“android.content.res.Resources$NotFoundException”

问题描述

嗨，我正在开发 Android Studio，但遇到了一个简单但奇怪的问题，我似乎无法解决。我已经将两个字符串数组定义为 xml 资源文件，包括在下面。

我有一个作为控制器的单例类，我尝试用 xml 文件中定义的那些字符串数组填充两个字符串数组列表。编译器似乎对编写的代码没有任何问题，甚至很乐意将这两个字符串数组作为自动完成的一部分提供。只有当代码运行时，我才会收到以下错误

android.content.res.Resources$NotFoundException

此时我已经尝试清理和重建项目，使缓存无效并重新启动 AS，并且我还尝试重命名 xml 中的字符串数组并重新编译代码。最初，我创建了一个新的 xml 资源文件来存储这些字符串数组，但目前我已将它们移到字符串资源文件中，但无论哪种方式都不起作用。

这些都不起作用，我真的很困惑问题可能是什么。我很感激你们可以提供的任何帮助。提前致谢。

这是字符串 xml 资源文件的相关位。

<resources>
    <string-array name="randomTriviaQuestionsArray">
        <item>As far as has ever been reported, no-one has ever seen an ostrich bury its head in the sand.</item>
        <item>Approximately one quarter of human bones are in the feet.</item>
        <item>Popeye’s nephews were called Peepeye, Poopeye, Pipeye and Pupeye.</item>
        <item>In ancient Rome, a special room called a vomitorium was available for diners to purge food in during meals.</item>
        <item>The average person will shed 10 pounds of skin during their lifetime.</item>
        <item>Sneezes regularly exceed 100 m.p.h.</item>
        <item>A slug’s blood is green.</item>
        <item>The Great Wall Of China is visible from the moon.</item>
        <item>Virtually all Las Vegas gambling casinos ensure that they have no clocks.</item>
        <item>The total surface area of two human lungs have a surface area of approximately 70 square metres.</item>
    </string-array>

    <string-array name="randomTriviaAnswersArray">
        <item>True.</item>
        <item>True – 52 bones in the feet and 206 in the whole body.</item>
        <item>True.</item>
        <item>False – It was the name for the entranceway to a stadium, nothing more.</item>
        <item>False – they will shed approximately 40.</item>
        <item>True</item>
        <item>True</item>
        <item>False – at a low orbit the Great Wall is visible, but no man-made structure is visible from outer space or the moon.</item>
        <item>True</item>
        <item>True</item>
    </string-array>
</resources>

这是在运行时发生错误的代码位。

public void setupQuestionBank(String questionFileName){
        List<String> qList;
        List<String> aList;

  switch(questionFileName){
            case "randomTrivia":
                qList = Arrays.asList(Resources.getSystem()
                                      .getStringArray(
                                      R.array.randomTriviaQuestionsArray));

                aList = Arrays.asList(Resources.getSystem()
                                      .getStringArray(
                                      R.array.randomTriviaAnswersArray));
                break;
            default:
                qList = new ArrayList<>();
                aList = new ArrayList<>();
        }

编辑：感谢 DevMike01，这是此问题的解决方案。使用活动或片段的上下文对象来访问资源。

public void setupQuestionBank(String questionFileName){
        List<String> qList;
        List<String> aList;

  switch(questionFileName, Context context){
            case "randomTrivia":
                qList = Arrays.asList(context.getResources()
                                      .getStringArray(
                R.array.randomTriviaQuestionsArray));

                aList = Arrays.asList(context.getResources()
                                      .getStringArray(
                                      R.array.randomTriviaAnswersArray));

                break;
            default:
                qList = new ArrayList<>();
                aList = new ArrayList<>();
        }

解决方案

您以错误的方式引用字符串数组。如果您在片段中，请替换为Resources.getSystem()，但如果代码在活动中，则只需直接调用即可。最后你的代码应该是这样的/getActivity().getResources()getResources()...getResources().getStringArray(...);
