looping in primitive array

[gong tji]

Hello everyone

I've tried to looping JSONArray to put it value into primitive array, but the result always null, here's my code (code 1) :

               try{
                JSONArray data = new JSONArray(str);

               for(int i=0;i<=data.length();i++)
               {
                   JSONObject videos = data.getJSONObject(i);
                   videoListData = new VideoData[]{new VideoData("aaa",getBitmap(videos.getString("url")))};
               }
                VideoAdapter adapter = new VideoAdapter(videoListData);
                recyclerView.setAdapter(adapter);

            } catch (JSONException e) {
                e.printStackTrace();
            }

I've tried to put it without looping and successful, here's my code (code 2):

VideoData[] videoListData = new VideoData[]{
                new VideoData("Email", getBitmap("xaf234")),
                new VideoData("Info", getBitmap("xaf290")),
                new VideoData("Info", getBitmap("1f7ucv5"))
};

Q  : How to implements code 2 in looping?

please help

Thanks.

Try print out videos.getString("url"). What you get?
