java - 在谷歌地图 json 数据中的地点类型中搜索特定项目

Question

我尝试在 JSON 数据中查找特定的项目类型。喜欢

 "types": [
        "restaurant",
        "food",
        "lodging",
        "point_of_interest",
        "establishment"
      ],
 "types": [
        "meal_delivery",
        "restaurant",
        "food",
        "point_of_interest",
        "establishment"
      ],

有时餐厅排名第 0 位，有时排名第 1 位。如何查找天气类型是否包含“餐厅”

Answer 1

您需要迭代“types”的 JSON 数组并检查它是否包含“restaurant” -

JSONObject obj = new JSONObject(jsonString);
JSONArray arr = obj.getJSONArray("types");
for (int i = 0; i < arr.length(); i++)
    if("restaurant".equals(arr.get(i).toString())){ 
          }
