Android Studio |中的StackOverflowError：null可能的修复？

Question

我在Android Studio中创建了一个类，并创建了一个HashMap并使用一些预定义的值对它进行了初始化，自此IDE发生内部错误。而现在，该班不会在Android工作室打开StackOverflowError: null。这是静态块中，我创建：

static

是大小这里的问题？解决这个问题的最好方法是什么？

Answer 1

没什么问题，

您的语法错误。你错过了"的,

变化之前，

hm.put("Arsenal VS Bournemouth,"M1X"); 

到

的所有线

hm.put("Arsenal VS Bournemouth", "M1X"); 

编辑。

但更好的方法是将数据保存为JSON文件或CSV文件，然后在运行时将其初始化为Victor K建议的值。
