Scrollfix for short list

[jasonsutor]

Changes:

1. Adding in project.properties for latest Eclipse ADT build.
2. Improving code for when call is made to setAdapter(null);
3. Improving footer height estimation, particularly when list items are variable height.
4. Improving selection of 0th or 1st element.
5. Adding in a listener for end of list reached. This allows for endless lists to be created, data can be loaded as user scrolls to bottom.

Hi, sorry for the late reply to this. Just had a test at it looks good. Will need to change the code style to adapt to previous style though but that's a minor. Would have preferred to have upgrade of sdk and adt in separate commits but it's def fine for now.

When there's very few items the OnEndOfListListener is triggered for every interaction with the list, like adding and removing items. Guess this is what's expected and up to the client to handle the event that's triggered.

Thank you, will merge later on today.

Thank you jasonsutor for these changes.

But I have one issue with this. When the list does not occupy whole screen(consider that list has only 0 or 1 or 2 elements) it constantly shows "Pull To Refresh...". Can you tell me how to handle this so that "Pull To Refresh..." will only be shown when user pulls the list down?

[jasonsutor]

It shouldn't, it only shows the "Pull To Refresh..." text when I haven't set the adapter. Once I set the adapter the footer view is adjusted to cover enough to scroll the text off screen. If your adapter views start out defaulted to a large size and then shrink as data is loaded then I can see that messing up the footer view calculation.

If we set the PullToRefreshListView height to wrap_content, the above mentioned issue occurs.
When I tried setting the height to fill_parent, it worked fine.

Thank you jasonsutor for this modifications.

Hi, I get the following errors when my adapter calls notifyDataSetChanged: http://pastebin.com/hDZJAiJF It seems like there's an issue with measuring the height of all the items in the list view? I'm not sure but that is where the error is pointing to. Any ideas as to how to fix this?

[jasonsutor]

Are your LayoutParams set for the new list elements? On line 428 (in API 2.2, other versions have no code on that line) of RelativeLayout.java it is checking mLayoutParams.width, it appears that isn't set which causes the null pointer exception

[alexfu]

Yes, I have the list view fill_parent both width and height.

[jasonsutor]

What about the list items though? The exception would be due to the item's layoutparams not being set.

[alexfu]

The list items layout width & height are set.. This error only comes up when I am on this branch. Master branch doesn't have this issue. I can show you the XML code for my list items?

It seems as though it doesn't like RelativeLayout being the child. I switched the list items layout to a LinearLayout and the error is gone.
