请帮忙展示一个安卓教程 我试过了，但没有成功

private void parseJsonFeed(JSONObject response) {
    try {
        JSONObject parent =  response.getJSONObject("response");

        JSONArray feedArray = parent.getJSONArray("items");

        for (int i = 0; i < feedArray.length(); i++) {
            JSONObject feedObj = (JSONObject) feedArray.get(i);

            FeedItem item = new FeedItem();
            item.setId(feedObj.getInt("id"));
            item.setName(feedObj.getString("name"));

            // Image might be null sometimes
            String image = feedObj.isNull("photo") ? null : feedObj
                    .getString("photo");
            item.setImge(image);
            item.setStatus(feedObj.getString("text"));
            item.setProfilePic(feedObj.getString("photo_75"));
            item.setTimeStamp(feedObj.getString("date"));

            // url might be null sometimes
            String feedUrl = feedObj.isNull("url") ? null : feedObj
                    .getString("url");
            item.setUrl(feedUrl);

            feedItems.add(item);
        }

        // notify data changes to list adapater
        listAdapter.notifyDataSetChanged();
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

我创建了一个 GitHub project，它使用您在 https://api.vk.com/method/wall.get?owner_id=-81865402&v=5.27 的服务并转换日期。

示例代码：

@Override
public void response(String response, Object... parameters) {
    stateTextView.setText("Getting Data Completed");

    ArrayList<Item> items = new JsonParser(response).getItems();
    Item item = items.get(1);
    PhotoAttachment photoAttachment = (PhotoAttachment)item.getAttachments().get(0);

    DateFormat formatter = new SimpleDateFormat("ss");
    Date date = null;
    try {
        date = formatter.parse(photoAttachment.getDate());
    } catch (ParseException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    stateTextView.setText(item.getText() + "\n\n"
                            + photoAttachment.getPhoto_75() + "\n\n"
                            + date.toString() + "\n\n"
                            + date.getDate() + "-" + (date.getMonth()+1) + "-" + (date.getYear()+1900) + " " 
                            + date.getHours()  + ":" + date.getMinutes() + ":" + date.getSeconds() + "\n\n");

    // you can move date conversion to the class date setter.
}
