解析Android字符串到JSONArray

-2

我有一个成功回来的JSONString，我想将它转换成JSONArray，我可以解析这些位。字符串成功返回，但是当我尝试在“结果”数组内的每个电影对象内记录“标题”时，它不会出现。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; 
}

你在这里得到任何错误？ – Rohit5k2

我没有收到错误。 Genymotion模拟器加载正常。如图所示，JSON字符串恢复正常。只是当我将JSONstring转换为jsonArray时，它不会记录单个标题。谢谢。 –

看起来一切都好。你尝试调试吗？ – Rohit5k2

尝试改变

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

到

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

并注释掉上面的日志语句，以便它可以很容易地
