如何在android中提取这个字符串变量？

Question

String test=
      ["1","Low-level programming language",true],
      ["2","High level programming language",false],
      ["3","Machine language",false],["4","All of the above",false],
      ["5","None of these",false]

我希望像[1","Low-level programming language",true]和其他文件一样将这个文件分成5种类型的字符串变量。

您可以在一个简单的正则表达式中拆分：

String [] splitStrings = test.split("\\],\\[");

您不希望只在逗号上拆分，因为您只想在方括号之间使用逗号。

下面是一个更完整的例子(如果您愿意的话，还有一个保持括号的正则表达式)

public static void main(String []args){
    String test="[\"1\",\"Low-level programming language\",true],[\"2\",\"High level programming language\",false],[\"3\",\"Machine language\",false],[\"4\",\"All of the above\",false],[\"5\",\"None of these\",false]";
    String [] splitStrings = test.split("(?!\\]),(?=\\[)");

    System.out.println(splitStrings[0]);
    System.out.println(splitStrings[1]);
    System.out.println(splitStrings[2]);
    System.out.println(splitStrings[3]);
    System.out.println(splitStrings[4]);
}
