我正在尝试使用 Gson 和 recyclerview 进行 JSON 处理。我的 JSON 不完全有效。在我的 JSON 中，food 字段只有一个字符串被引用，而另一个则不被引用。请参阅下面我的 JSON...
[
{"quantity" = 2,
"price" = 15,
"food" = "Fried" Rice},
{"quantity" = 2,
"price" = 20,
"food" = "Rice" and Stew}
]
您可以看到 Fried 有引号，而 Rice 没有引号，同样，Rice 和 Stew 也有同样的情况。最初是这样的......
[
{quantity = 2,
price = 15,
food = Fried Rice},
{quantity = 2,
price = 20,
food = Rice and Stew}
]
我的 Activity 类代码...
Bundle extras = getIntent().getExtras();
if (extras != null) {
String listOfFood = extras.getString("foods");
listOfFood = listOfFood.replaceAll("([\\w]+)[ ]*=", "\"$1\" ="); // to quote before = value
listOfFood = listOfFood.replaceAll("=[ ]*([\\w@\\.]+)", "= \"$1\""); // to quote after = value, add special character as needed to the exclusion list in regex
listOfFood = listOfFood.replaceAll("=[ ]*\"([\\d]+)\"", "= $1"); // to un-quote decimal value
listOfFood = listOfFood.replaceAll("\"true\"", "true"); // to un-quote boolean
listOfFood = listOfFood.replaceAll("\"false\"", "false"); // to un-quote boolean
Log.d(TAG, "onCreate: "+listOfFood);
GsonBuilder builder = new GsonBuilder();
Gson mGson = builder.create();
List<FoodOrder> posts = new ArrayList<FoodOrder>();
posts = Arrays.asList(mGson.fromJson(listOfFood, FoodOrder[].class));
adapter = new RecyclerViewAdapter(FoodsOrderedActivity.this, posts);
recyclerView.setAdapter(adapter);
}
我需要将炒饭放在引号之间的食品字段，作为米饭和炖菜的引号，或者是否有解决方法，我想知道。
谢谢
最佳答案
基于您的代码。 (尝试将 listOfFood 转换为 JSON )
我修改了你的两行代码如下
listOfFood = listOfFood.replaceAll("(\\s*)([^{,\\s]+)(\\s*)=","$1\"$2\"$3:"); // to quote before = value and replace = by :
listOfFood = listOfFood.replaceAll("(:\\s*)([^\\s,{}](\\s*[^\\s,{}]+)*)", "$1\"$2\""); // to quote after = value (= now became :)
