原本用的json是資料直接打在程式碼裡，現在想要抓URL但是看了很多偏範例，還是不會改，怎麼把它改成用URL抓並且一樣是URLData

@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		newContext = getActivity();
		try {
			URLData = new JSONObject(
					"{"error":"ok","status":0,"data":[{"Art":5,"news":450,"bkk":680},{"Art":5,"news":460,"bkk":690}]}")
.getJSONArray("data");
} catch (JSONException e) {
		}
	}
@Override
	public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
		View view = inflater.inflate(R.layout.watch, null);
		List<TimesEntity> watchList = new ArrayList<TimesEntity>();
		JSONObject data = null;
		try {
			for (int i = 0; i < URLData.length(); i++) {
				data = URLData.getJSONObject(i);
				timesList.add(new TimesEntity(data.getString("Art"), data.getDouble("news"), data.getDouble("bkk")));
			}
		} catch (Exception e) {	
		}
	}
