how to remove a row from a Listview? I have an Adapter that takes care of the List and when I try mAdapter.remove(Object) it does not remove the "Object" I passed but instead the last row on the list. I have tried different ways and it always ends up deleting the last row.

In my app I have nice ExpandableListView. I would like sometime, depending of situation, to expand some or all groups. I would also like to be able to remove/hide groups, expand all and basically have (visually) ExpandableListView without groups. I looked at all available methods for ExpandableListView and couldn't find any that would do what I want to do.

Here replpulateList() method will add to listview items. It doesn't remove/replace all listview items.

View 1 Replies View RelatedThere must be a way to do this. How can you tell a ListView that has a header to not scroll it when the user scrolls the contents? I want it to stay in a "stuck" position so that the user can always see what column the content applies to.

At the moment I have cell's height 100dp, I need that cell's height will depend on device, I mean I have here 5 cells showing at login screen in ListView and I need that these 5 rows will fit the ListView (cell's height = ListView's height/5).
I have a listview within an activity and at the bottom of the screen I have a scrollable gallery, my problem is making the listview clickable, I would normally use the listview position by doing if(position == 3) and then create the intent but postion is being used by my gallery. I listview is in the main.xml populated by an array.xml, can I add an id i.e android:id in the arrays.xml and create an intent with that, or can I create a listactivity and still use position to fire an intent if so how would I do this.

i want to implement listview with uses different xml layouts for rows depending on underlying item. A non optimal solution will be int getView method just to inflate every time a new view depending on the item from the adapter. Is there a better way to do this?
View 2 Replies View Relatedis it possible to let my ListView show 2 different rows? On the picture you can see at the top something like a "teaser", the other rows are normal ListView. The screenshot is from the iPod. With their framework it is possible to show 2 different row styles. I badly need this on Android... Otherwise I would use a tabel design. But adding rows dynamically would be such an overhead instead of using ListView SimpleAdapter addItem...
View 2 Replies View RelatedIs there a way to do groups in a listview? Like I have a list of certain states, each state has its own sublist. I'd sort of like to replicate the HTML optgroup/option setup where you have a parent group then child groups. Is there a way to do this built in or would I have to do something tricky with a custom view for Parent elements then switch the view back to the child element style.

I have a listview that's populated by rows that get their data from a web server. It all works totally fine except I want to have a refresh button to re-download the data. I'm getting the data through an asynctask (getting the data in doinbackground) and then setting the listadapter in onpostexecute. All I do to run the asynctask which should take care of everything is run
new PopulateListTask().execute();
However, in my optionsSelect method, creating a new asynctask just like I did in oncreate doesn't do anything. It doesn't even enter doInBackground. I've tried using listView.invalidate() and listView.invalidateViews(). Is there some special way I'm supposed to repopulate a listview?
My only guess is that since I'm using a custom adapter, my getView method is creating some kind of error, but that wouldn't explain why it's not even entering my asynctask's doInBackground method. Thoughts?
Posting some code. This is a trimmed down version.

I'm getting this in my logcat when executing my asynctask the 2nd time. Any idea what it means? I tried googling to no avail.
I'm trying to make a layout that is something similar to how the android market is...where say under comments there is what appears to be a ListView but it does not scroll (the whole page scroll but not the comments). I'm not sure if its even a ListView but I want something that looks like the list view (ie. have those divider bars and what not but NOT SCROLLABLE). There are people suggesting to use a LinearLayout instead of a ListView but I also what the items to be clickable and open a new activity. Please help?
My current layout tree is like so
<LinearLayout>
<ScrollView>
<RelativeLayout>
I am looking to put content inside the RelativeLayout.
How i can use custom listview with textview and imageview.i tried following code
CODE:...............
But it is not working.
I have a listview with a bunch of items in it, each item has its own background, the problem is that if i only have one item in a list, the rest of the "empty" slots of the list is black. I tried applying a background around the listview and also on the view that sorrounds it (relativeView) and i get a strange margin around the whole list like the picture at the bottom. The question i have is, how can i remove the actual "borders" around the list so it still fills upp its parent ?
