如何在Android中获取FB朋友生日

Question

我使用此示例代码https://github.com/chrtatu/FacebookFriendsList来获取FB朋友名单和他们的名字和个人资料图片。
在这里，我尝试获得他们的DOB，但是代替DOB，我得到了null值。
请帮忙取回。

我的代码：

String[] facebook_permissions = { "user_photos", "friends_birthday", "friends_photos" };

    public class FriendListAdapter extends BaseAdapter implements SectionIndexer { 
    private LayoutInflater mInflater; 
    private String[] sections; 
    private GetProfilePictures picturesGatherer = null; 
    FriendsList friendsList; 
    Hashtable<Integer, FriendItem> listofshit = null; 

    public FriendListAdapter(FriendsList friendsList) { 
     Log.d(LOG_TAG, "FriendListAdapter()"); 
     this.friendsList = friendsList; 
     sections = new String[getCount()]; 
     listofshit = new Hashtable<Integer, FriendItem>(); 
     for (int i = 0; i < getCount(); i++) { 
      try { 
       sections[i] = jsonArray.getJSONObject(i).getString("name").substring(0, 1); 
       sections[i] = jsonArray.getJSONObject(i).getString("birthday").substring(0, 2); 
      } catch (JSONException e) { 
       sections[i] = ""; 
       Log.e(LOG_TAG, "getJSONObject: " + e.getMessage()); 
      } 
     } 
     if (picturesGatherer == null) { 
      picturesGatherer = new GetProfilePictures(); 
     } 
     picturesGatherer.setAdapterForListener(this); 
     mInflater = LayoutInflater.from(friendsList.getBaseContext()); 
    } 

    public int getCount() {

     if (jsonArray == null) 
      return 0; 
     return jsonArray.length();

    public long getItemId(int position) {

     return position;

      convertView.setTag(friendItem); 
     } 
     else {

     friendItem.friendPicture = (ImageView) convertView.findViewById(R.id.picture_square); 
     friendItem.friendName = (TextView) convertView.findViewById(R.id.name);

     listofshit.put(position, friendItem); 

     return convertView; 
    } 

    public int getPositionForSection(int position) { 
     return position; 
    } 

    public int getSectionForPosition(int position) { 
     return position;

    public Object[] getSections() { 
     return sections;

} 

class FriendItem { 
    TextView friendDob; 
    int id; 
    ImageView friendPicture; 
    TextView friendName; 
    RelativeLayout friendLayout; 

}

String query = "select name, uid, pic_square, birthday from user where uid in 
(select uid2 from friend where uid1=me()) order by name"; 

Answer 1

相反的这两行代码：

sections[i] = jsonArray.getJSONObject(i).getString("name").substring(0, 1); 
sections[i] = jsonArray.getJSONObject(i).getString("birthday").substring(0, 2); 

使用下面两行：

sections[i] = jsonArray.getJSONObject(i).getString("name").substring(0); 
sections[i] = jsonArray.getJSONObject(i).getString("birthday").substring(1);

请参考下面的方法：也看看这个例子太

http://www.androidhive.info/2012/03/android-facebook-connect-tutorial/

public void getProfileInformation() { 
mAsyncRunner.request("me", new RequestListener() { 
    @Override 
    public void onComplete(String response, Object state) { 
     Log.d("Profile", response); 
     String json = response; 
     try { 
      JSONObject profile = new JSONObject(json); 
      // getting name of the user 
      String name = profile.getString("name"); 
      // getting email of the user 
      String email = profile.getString("email"); 
      //getting user birthday 
      String birth_day=profile.getString("birthday"); 

      runOnUiThread(new Runnable() { 

       @Override 
       public void run() { 
        Toast.makeText(getApplicationContext(), "Name: " + name + "\nEmail: " + email, Toast.LENGTH_LONG).show(); 
       } 

      }); 

     } catch (JSONException e) { 
      e.printStackTrace(); 
     } 
    } 

    @Override 
    public void onIOException(IOException e, Object state) { 
    } 

    @Override 
    public void onFileNotFoundException(FileNotFoundException e, 
      Object state) { 
    } 

    @Override 
    public void onMalformedURLException(MalformedURLException e, 
      Object state) { 
    } 

    @Override 
    public void onFacebookError(FacebookError e, Object state) { 
    } 
});
