[英]fetch photos from facebook album in android
我試圖從android中的facebook的特定相冊中獲取所有照片,我使用facebook android sdk來完成任務但問題是,我不知道訪問相冊內的照片需要什么URL請求?
https://graph.facebook.com/ALBUM_ID/photos
如果是特定的人那么:
https://graph.facebook.com/me/albums/
然后選擇相冊ID,然后使用第一個電話
編輯
您還需要在Permission String數組中創建Facebook對象時給予權限,還需要添加user_photos
以便能夠加載照片
代碼為我工作。
我有兩個功能 - 一個是獲取Album id,而另一個是從該特定專輯中檢索所有圖像。
首先使用test()
函數然后使用downloadpic()
。
public void test()
{
facebook.getAccessToken();
JSONArray albumss=null;
String response = null;
try {
response = facebook.request("me/albums");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONObject json = null;
try {
json = Util.parseJson(response);
} catch (FacebookError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray albums = null;
try {
albums = json.getJSONArray("data");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (int i =0; i < albums.length(); i++) {
JSONObject album = null;
try {
album = albums.getJSONObject(i);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
try {
//Here I have selected Profile pic album.
if (album.getString("type").equalsIgnoreCase("profile")) {
// JSONArray al=null;
wallAlbumID = album.getString("id");
// Now you have album id in wallAlbumID(global varible).
Log.d("JSON", wallAlbumID);
break;
}
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
現在使用downloadpic()
:
void downloadpic( )
{
facebook.getAccessToken();
String response = null;
try {
response = facebook.request(wallAlbumID+"/photos");
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONObject json = null;
try {
json = Util.parseJson(response);
} catch (FacebookError e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
JSONArray photos = null;
try {
photos = json.getJSONArray("data");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
for (int i =0; i < photos.length(); i++) {
JSONObject a = null;
try {
a = photos.getJSONObject(i);
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String testing = null;
try {
testing = a.getString("source");
} catch (JSONException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
\
URL value=null;
try {
value=new URL(testing);
//Now you have URL of that particular image use it in your way
} catch (MalformedURLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
break;
}
}
