Question

我遇到了不寻常的问题。当我访问activity（LevelTwoActivity）中的字符串资源时，它会给我以下问题。

 java.lang.RuntimeException: Unable to start activity ComponentInfo{com.package/com.package.LevelTwoActivity}: java.lang.IndexOutOfBoundsException

代码中的行如下

    LevelTwoVerbiageModel verbiageModel = new Gson()
            .fromJson(getString(R.string.levelTwoVerbiage), LevelTwoVerbiageModel.class);

字符串reosurce如下：

<string name="levelTwoVerbiage">
    {\"arrays\":[[[
        \"I like to greet others\",
        \"I really like to greet others\",
        \"I want to greet others\"],[],[],
        ....
        ....
        \"I really don’t want\",
        \"I don’t feel very safe\",
        \"I really don’t feel very safe\"
]]]}
</string>

我访问的资源是json字符串，长度约为135000个字符。它存储在values文件夹下，但存储在名为arrays-level-two.xml的文件中。以一种奇怪的方式，代码一直在工作，直到我更新了我的测试设备。现在，它没有用。该代码在具有不同api级别的其他测试设备上完美运行。

失败的设备详细信息是：

Device name: MI A1
Android version: 8.0.0
Android patch level: 1 April 2018
Build number: OPR1.170623.026.V9.5.10.0.DHMIFA

我无法确定访问字符串资源的原因：java.lang.IndexOutOfBoundsException.

有人有任何指针出错吗？

提前致谢。 -Rahul

Answer 1

@Rahul - 我不知道为什么Android Oreo会抛出此异常。这可能是由于字符串资源中使用的字符数量增加了限制。使用大约135000个字符的字符串对我来说也是一种不好的做法。相反，我建议您使用String[]，然后在代码中将其作为字符串数组<string-array name="my_items"> <item>Item1</item> <item>Item2</item> <item>Item3</item> ... </string-array>，然后使用它。

这样你甚至不需要使用Gson来解析Json。

示例：

的strings.xml

String[] myItems = getResources().getStringArray(R.array.my_items);

MyFile.java

myItems[index_you_want_to_access]

将其用作connect

getString（R.string.res_name）给出java.lang.IndexOutOfBoundsException
