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

Question

这个问题已经有答案了:

Why can't I use Resources.getSystem() without a Runtime error? (3 个回答)

已关闭 3 年前。

您好，我正在使用 Android Studio，我遇到了一个简单但奇怪的问题，我似乎无法解决。我已将两个字符串数组定义为 xml 资源文件，如下所示。

我有一个充当 Controller 的单例类，我尝试使用 xml 文件中定义的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，甚至很乐意提供这两个字符串数组作为自动完成的一部分。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至字符串资源文件中，但无论哪种方式都不起作用。

这些都不起作用，我只是对问题所在感到非常困惑。我很感谢你们能提供的任何帮助。提前致谢。

这是字符串 xml 资源文件的相关部分。

<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>

这是运行时发生错误的代码段。

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:这是此问题的解决方案，感谢 DevMike01。使用 Activity 或 Fragment 的 Context 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<>();
        }

您以错误的方式引用字符串数组。替换Resources.getSystem()与 getActivity().getResources()如果您在 fragment 中，但如果代码在 Activity 中，只需调用 getResources()直接地。最后你的代码应该是这样的 ...getResources().getStringArray(...);/
