Googleのapiからの応答を受信した後、どのように地図上に駆動道路を表示することができますか？ストリートビューに切り替えるにはどうすればよいですか？ 。ここgoogle direction apiからの応答を受け取った後、
私のコードです：ここ
RequestQueue queue = Volley.newRequestQueue(this);
String url = "https://maps.googleapis.com/maps/api/directions/json?origin=Disneyland&destination=Universal+Studios+Hollywood4&key=AIzaSyBX40zJvRu0PBVs5iA0xG_cmdpVAUKYmmQ";
// Request a string response from the provided URL.
StringRequest stringRequest = new StringRequest(Request.Method.GET, url,
new Response.Listener<String>() {
@Override
public void onResponse(String response) {
// Display the first 500 characters of the response string.
Log.e("Response is: ", response.toString());
////////////////json response //////////
try {
String responseString;
JSONObject responseObject = (JSONObject) new JSONTokener(response.toString()).nextValue();
responseString = responseObject.getString("status");
JSONArray routesArray = responseObject.getJSONArray("routes");
JSONObject route = routesArray.getJSONObject(0);
JSONArray legs;
JSONObject leg;
JSONArray steps;
JSONObject dist;
Integer distance;
if (route.has("legs")) {
legs = route.getJSONArray("legs");
leg = legs.getJSONObject(0);
steps = leg.getJSONArray("steps");
int nsteps = steps.length();
for (int i = 0; i < nsteps; i++) {
JSONObject step = steps.getJSONObject(i);
if (step.has("distance")) {
dist = (JSONObject) step.get("distance");
if (dist.has("value"))
distance = (Integer) dist.get("value");
}
}
} else
responseString = "not found";
} catch (Exception e) {
e.printStackTrace();
}
////////////////////////////
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error) {
Log.e("Response is: ", "error");
}
});
