您可以使用 GSON 库来实现这一点.

You can use the GSON library to accomplish this.

 ArrayList<String> mylist = new ArrayList<String> ();
 mylist.add("abc");
 mylist.add("cfd");
 mylist.add("ert");
 mylist.add("fg");
 mylist.add("ujk");
 String json = new Gson().toJson(mylist);

您可以参考 GSON 用户指南以获得更多支持.

You can refer to the GSON User Guide for more support.
