遍历JSONObject

public void initialFilter(JsonNode filter) {
	// 智能数据来源
	smartDataList = new ArrayList<String>();
	String smart = filter.get("order_by").toString();
	try {
		JSONObject obj = new JSONObject(smart);
		Iterator<String> keys = obj.keys();
		while (keys.hasNext()) {
                // 这是把所有的key添加到list了
			smartDataList.add(keys.next());
		}
			
	} catch (JSONException e) {
		e.printStackTrace();
	}
		
	ArrayAdapter<String> smartAdapter = new ArrayAdapter<String>(mActivity,android.R.layout.simple_list_item_1,smartDataList);
	smartView = LayoutInflater.from(mActivity).inflate(R.layout.store_filter_smart,null);
	smartListView = (ListView) smartView.findViewById(R.id.lv_shop_smart);
	smartListView.setAdapter(smartAdapter);
}
