Question

我以字符串形式从Google Directions API获得了jSON响应。我如何获取＆＃34;机动＆＃34;这个对象？我想将它放在另一个JSON数组中，稍后我将变成一个字符串。

这是我的json：https://maps.googleapis.com/maps/api/directions/json?origin=Disneyland&destination=Universal%20Studios%20Hollywood4&key=AIzaSyDeTp_6tFa2cUan9wUw3qgFi5-dm8xGRHs

这是我到目前为止所做的事情：

public JSONArray parseDirectionsForNavigation(String jsonData)
    {
        JSONArray jsonArray_live = null;
        JSONObject jsonObject_live;

        try {
            jsonObject_live = new JSONObject(jsonData);
            jsonArray_live = jsonObject_live.getJSONArray("routes").getJSONObject(0).getJSONArray("legs").getJSONObject(0).getJSONArray("steps");
        } catch (JSONException e) {
            e.printStackTrace();
        }
        return jsonArray_live;
    }

Answer 1

JSONArray arr_routes = jsono.getJSONArray("routes");

JSONArray arr_legs = jsono.getJSONArray("legs");

JSONArray arr_steps = jsono.getJSONArray("steps");

for (int i = 0; i < arr_steps .length(); i++) {
                    JSONObject object = jarray.getJSONObject(i);

                    //create a string array of some sort.
                    String[] maneuvers = object.getString("maneuvers")

                }

您可以尝试很多其他解析方法，但在进入内部时，json可以这样做
