I would just write your own class that implements the ListAdapter interface.
It is not too bad, and I think it would be a good learning experience.

I've worked a lot with ArrayAdapters and ListView/GridView. I've
never had a problem like you describe. It definitely isn't a
fundamental flaw. Note that ListView recycles views, so that may be
why you are getting the state of the checkbox transferred from one
list item to the next.

Can you post your getView code? Are you using a holder?

Yeah, had similar problems in an ExpandableListAdapter when too much
processing time was spent in overridden getChildView or getGroupView.
So perhaps a solution to your problem is to minimise the amount of
work being done in your getChildView function.

In a generalist sense adapter pattern is a bridge between 2 classes
that have some common functionality, but the interfaces are not
reusable between them. Ideally the need for adapter arises when we
have two classes that are not developed keeping in mind interaction
between them.
Strategy pattern,
You're right.
Even better! :-)
If you back just a simple java.util.List, then the ArrayAdapter will
take care of most, if not all, of your requirements for a list-view.

THANK YOU

If the NullPointerException is exactly on the statement you pointed out,
then spinner_drawings must be null, suggesting something is going wrong
with the loading of your layout.
and looking at my code again i realized that findViewById() should read

Hi Mark,
setContentView is called before i call findViewByid and the layout does have
a spinner element with the proper name.

I changed the code to just use the following array for testing purposes and
i still get the null pointer exception. anyone have any ideas as to why?
String[] array = {"this", "is", "driving", "me", "crazy"};
Spinner spinner_drawings = (Spinner) findViewById(R.id.spinner_drawings);

I changed the code to read

Im catching the exception which is java.lang.NullPointerException.
I don't understand why tho. There is data in the array, i see it get filled

That stops it from crashing but exception.getMessage() is null. Is there
something i need to do so that the message is not null?
What else should I be looking for?
Thanks!

1. You are checking for null after using it above twice which is
redundant..
2. Catch the exception
3. If catching and you are getting a NullPointer then use Lod.e(TAG,
exception.getMes

Hi,
Can any one help me to get the concept of ListView?
I would like to display list of video's link in my xml.
Could you please tell me how can I achieve this requirements?
If I clicks any one of videos within the list of videos then it will display
the corresponding video in the same page(xml
You're doing it onItemClick, so it's probably invalidated for redraw
anyway. In my case the items are coming in on a separate thread. If I
was to click an item it would update then. But of course that's a very
weird interaction to touch the screen and suddenly all of the updates
show up at once.
I used notifyDataSetChanged() and it works fine for me. Here's my
complete code with the notifyDataSetChanged() at the bottom in the
selection listener:
package com.pocketjourney.location.map;
import java.util.List;
import android.content.Context;
import android.view.LayoutInflater;
import and
I implemented the async incoming data on a separate thread which adds
the items to a Vector that is connected to the view through my custom
adapter (inherits BaseAdapter). When new items come in the list does
not update, unless I scroll it with my finger to signal a redraw. I
tried lots of things.
Try notifyDataSetChanged() - it has no documentation but it seems to
do what you want.
