的Java
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("post_type"));
item.setTimeStamp(feedObj.getString("date"));
// Image might be null sometimes
String image = feedObj.isNull("photo") ? null : feedObj
.getString("photo");
item.setImge(image);
item.setStatus(feedObj.getString("text"));
All code work till there how to get data from attachments
***JSONObject response1 = response.getJSONObject("response");
feedArray = parent.getJSONArray("items");***
JSONArray feedArray1 = response1.getJSONArray("attachments");
for (int i1 = 0; i1 < feedArray1.length(); i1++) {
JSONObject feedObj1 = (JSONObject) feedArray1.get(i1);
FeedItem item1 = new FeedItem();
item.setProfilePic(feedObj1.getString("photo_75"));
}
// url might be null sometimes
String feedUrl = feedObj.isNull("url") ? null : feedObj
.getString("url");
item.setUrl(feedUrl);
feedItems.add(item);
}
} catch (JSONException e) {
e.printStackTrace();
}
}
在此先感谢
推荐答案
您正在寻找在错误的对象的附件。 attachmetnts是项属性。 而不是
you are looking for attachments in wrong object. "attachmetnts" is property of item. instead of
JSONArray feedArray1 = response1.getJSONArray("attachments");
使用
JSONArray feedArray1 = feedObj.getJSONArray("attachments");
在你的情况的 feedObj包含项目对象。
,以达到照片: 删除行:
to get photo : Remove lines :
String image = feedObj.isNull("photo") ? null : feedObj
.getString("photo");
item.setImge(image);
和它更改为:
for (int i1 = 0; i1 < feedArray1.length(); i1++) {
JSONObject attachment = (JSONObject) feedArray1.get(i1);
JSONObject photo = (JSONObject) attachment.getJSONObject("photo");
item.setImge(photo);
item.setProfilePic(photo.getString("photo_75"));
item.setStatus(photo.getString("text"));
}
