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} ]我的活动类代码...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。

根据您的代码。(尝试转换listOfFood
为 JSON )我修改了 2 行代码,如下所示
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 :)

json 结构应该是这样的:
[{"数量" : 2, "价格" : 15, "食物" : "炒饭"}, {"数量" : 2, "价格" : 20, "食物" : "米饭和炖菜"}]

json 结构应如下所示 [ { "Key1" : "value1", "Key2" : "value2", }, { "Key1" : "value1", "Key2" : "value2", }
