解析Android字符串到JSONArray

-2

我有一個成功回來的JSONString，我想將它轉換成JSONArray，我可以解析這些位。字符串成功返回，但是當我嘗試在「結果」數組內的每個電影對象內記錄「標題」時，它不會出現。解析Android字符串到JSONArray

public List<MovieItem> fetchItems() { 

List<MovieItem> items = new ArrayList<>(); 

try { 
    String url = Uri.parse("https://api.themoviedb.org/3/movie/popular") 
      .buildUpon() 
      .appendQueryParameter("api_key", API_KEY) 

      .build().toString(); 


    String jsonString = getUrlString(url); 
    Log.i(TAG, "Received JSON: " + jsonString); 


    JSONObject jsonBody = new JSONObject(jsonString); 
    JSONArray photoJsonArray = jsonBody.getJSONArray("results"); 


    for(int i = 0; i < photoJsonArray.length(); i++){ 

     JSONObject jsonPart = photoJsonArray.getJSONObject(i); 

     Log.i("title", jsonPart.getString("title")); 
    } 


} catch (IOException ioe) { 
    Log.e(TAG, "Failed to fetch items", ioe); 
} catch (JSONException je) { 
    Log.e(TAG, "Failed to parse", je); 
} 
return items; 
}

你在這裏得到任何錯誤？ – Rohit5k2

我沒有收到錯誤。 Genymotion模擬器加載正常。如圖所示，JSON字符串恢復正常。只是當我將JSONstring轉換爲jsonArray時，它不會記錄單個標題。謝謝。 –

看起來一切都好。你嘗試調試嗎？ – Rohit5k2

嘗試改變

Log.i("title", jsonPart.getString("title"));

到

Log.i(TAG, "Title: " + jsonPart.getString("title"));

並註釋掉上面的日誌語句，以便它可以很容易地
