这是我目前用于解析的代码
JSONArray ingredients = resultObject.getJSONArray("ingredients");
for(int o = 0; o < ingredients.length(); o++) {
JSONObject ingredientsJSONObject = ingredients.getJSONObject(o);
String quantity = String.valueOf(ingredientsJSONObject.getInt("quantity"));
ingredient.add(quantity + " " +
ingredientsJSONObject.getString("measure") + " " +
ingredientsJSONObject.getString("ingredient"));
}
“数量”的某些值不是整数，但我也尝试过使用：
String quantity = String.valueOf(ingredientsJSONObject.getDouble("quantity"));
