グローバル動的ArrayListのは、更新/

Question

緯度と長い変数は、現在位置があるGoogleの場所検索APIからJSON形式でボレー応答を取得中に関数に変更しないで、ここで

if(lat!=0.0||longg!=0.0){ 
search(); 
details(placeId); 
} 

検索（）関数.... placeIDでありますグローバルArrayListのは、私がここに詳細 のための私の詳細機能にplaceId（グローバルのArrayList）を使用する変数

public void search() { 
String url ="https://maps.googleapis.com/maps/api/place/nearbysearch/json?Location="+lat+","+longg+"&radius=5000&type=hospital&name=Hospital&key=AIzaSyA71lHTBWnb8uNvUI0N8ch8lhvla_0pM8"; 
Log.e("URL 1st : ", url); 
final ArrayList<String> idd = new ArrayList<>(); 
Response.Listener<JSONObject> myListener = new Response.Listener<JSONObject>() { 
@Override 
public void onResponse(JSONObject response) { 
String status = null; 
try { 
status = response.getString("status"); 
} catch (JSONException e) { 
e.printStackTrace(); 
} 
if (status != null && status.equals("ZERO_RESULTS")) { 
Log.e("Response Status: ", "search was successful but returned no results.This may occur if the search was passed a latlng in a remote location."); 
Toast.makeText(NearByHospitals.this, "You are in remote location.\nNo Nearby Hospitals", Toast.LENGTH_SHORT).show(); 
} else if (status != null && status.equals("OVER_QUERY_LIMIT")) { 
Log.e("Response Status: ", "indicates that you are over your quota."); 
} else if (status != null && status.equals("REQUEST_DENIED")) { 
Log.e("Response Status: ", "indicates that your request was denied, generally because of lack of an invalid key parameter."); 
} else if (status != null && status.equals("INVALID_REQUEST")) { 
Log.e("Response Status: ", "generally indicates that a required query parameter (location or radius) is missing."); 
} else { 
int sizeOfResponse = 0; 
try { 
sizeOfResponse = response.getJSONArray("results").length(); 
} catch (JSONException e) { 
e.printStackTrace(); 
} 
for (int i = 0; i < sizeOfResponse; i++) { 
try { 
if (response.getJSONArray("results").getJSONObject(i).has("opening_hours") && response.getJSONArray("results").getJSONObject(i).getJSONObject("opening_hours").getBoolean("open_now")) { 
placeId.add(response.getJSONArray("results").getJSONObject(i).getString("place_id")); 
Log.e("iddd", response.getJSONArray("results").getJSONObject(i).getString("place_id")); 
locat.add(String.valueOf(response.getJSONArray("results").getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lat")) + "," + String.valueOf(response.getJSONArray("results").getJSONObject(i).getJSONObject("geometry").getJSONObject("location").getDouble("lng"))); 
} 
} catch (JSONException e) { 
e.printStackTrace(); 
} 
} 
} 
} 
}; 
Response.ErrorListener myErrorListener = new Response.ErrorListener() { 
@Override 
public void onErrorResponse(VolleyError error) { 
Toast.makeText(NearByHospitals.this, error.getMessage(), Toast.LENGTH_LONG).show(); 
} 
}; 
JsonObjectRequest myRequest = new JsonObjectRequest(Request.Method.GET,url, null, myListener, myErrorListener); 
Volley.newRequestQueue(NearByHospitals.this).add(myRequest); 
} 

であることは（私の詳細である）機能

public void details(ArrayList<String> strId) { 

    for (int i = 0; i < strId.size(); i++) { 
     try { 
      String url2 = "https://maps.googleapis.com/maps/api/place/details/json?placeid=" + strId.get(i) + "&key=AIzaSyA718lHTBWnb8uNvUI0N8ch8lhvla_0pM8"; 
      Log.e("URL2 ", url2); 
      Response.Listener<JSONObject> myListener2 = new Response.Listener<JSONObject>() { 
       @Override 
       public void onResponse(JSONObject response) { 
        String status = null; 
        try { 
         status = response.getString("status"); 
        } catch (JSONException e) { 
         e.printStackTrace(); 
        } 
        if (status != null && status.equals("ZERO_RESULTS")) { 
         Log.e("Response Status: ", "indicates that the reference was valid but no longer refers to a valid result. This may occur if the establishment is no longer in business."); 
        } else if (status != null && status.equals("OVER_QUERY_LIMIT")) { 
         Log.e("Response Status: ", "indicates that you are over your quota."); 
        } else if (status != null && status.equals("REQUEST_DENIED")) { 
         Log.e("Response Status: ", "indicates that your request was denied, generally because of lack of an invalid key parameter."); 
        } else if (status != null && status.equals("INVALID_REQUEST")) { 
         Log.e("Response Status: ", "generally indicates that the query (reference) is missing."); 
        } else { 
         if (status != null && status.equals("OK")) { 
          try { 
           hosNames.add(response.getJSONObject("result").getString("name")); 
           phoneNumbers.add(response.getJSONObject("result").getString("international_phone_number")); 

          } catch (JSONException e) { 
           e.printStackTrace(); 
          } 
         } 
        } 
       } 
      }; 
      Response.ErrorListener myErrorListener2 = new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        Toast.makeText(NearByHospitals.this, error.getMessage(), Toast.LENGTH_LONG).show(); 
       } 
      }; 
      JsonObjectRequest myRequest2 = new JsonObjectRequest(Request.Method.GET, url2, null, myListener2, myErrorListener2); 
      Volley.newRequestQueue(NearByHospitals.this).add(myRequest2); 

     } catch (NullPointerException l) { 
      l.printStackTrace(); 
     } 
    } 

} 

問題はありますが、場所IDは空でサイズはゼロです。私はデバッグ中にこの変数をチェックします。nすべてはうまくいきます。arraylistはデバッグ中に変更されました。私は知らないどこが間違っているのですか？

Answer 1

以下から：メソッドの検索で

search(); 
details(placeId); 

（）あなたが詳細（placeId）を実行するときに、あなたが引数として渡しているplaceIdは、ISない非同期スレッドでplaceIdリストを変更していますリストの変更を保証するものではありません。あなたがvolleyレスポンス内でplaceIdを埋めると、詳細（placeId）を呼び出すことができます。
