Android :: ExpandableListView Won't Redraw

Jul 29, 2009

I have an expandable list view with a static array for the group data and an SQLite database for the child data. It is implemented with the BaseExpandableListAdapter and works great, except, when I edit the database to delete or add children to the list I do not see the changes onscreen. It looks like I can use the registerDataSetObserver method to notify the adapter and expandable list of a data change. What I have to do in the callback to make Android redraw the list after data changes is what I need to know. Can I do it? Documentation on this part of the SDK is a bit sparse and expandable list view example code is not a good match. Can anyone offer advice on how to use a DataSetObserver? It feels like I have to switch over to a Cursor type adapter.

Android :: ExpandableListView - Is Conditional Expansion Possible

Aug 12, 2010

I have an ExpandableListView bound to a SQLite database. To simplify things, lets assume the database contains two columns: title and body. In the ExpandableListView, there is a group for each title, and a childfor each corresponding body.

Now to make things more interesting, some of the rows in the SQLite database do not have a body (that is... they only have a title). As you can see, if there is no body, then there is no reason to expand the group... because the child will be empty (i.e. String body == "").

I'm searching for a way to catch a situation like this, and skip the group's expansion. I don't want a blank child to be expanded. To put it in psuedo code, I want something like this:

Android :: ExpandableListView Indicator Over My Text

Dec 2, 2009

I'm using an ExpandableListView in one of my activity in a RelativeLayout


And I'm using a custom expandableListAdaptaer which group view is:


(Found on examples of API_Demos, ExpandableList1)

A user of my application report me this photo As you can see, the indicator of group items is over the text of group item despite the padding of 36...

And if I'm running emulator WVGA800 or an emulator with "abstracted LCD density" to 240 I have the same problem, but with my phone (HTC G1), I don't have any problem.

What is strange is that I try the application API_Demo with an emulator WVGA800 or an emulator with "abstracted LCD density" to 240 and I go to ExpandableList1 activity and all is alright !

I also try to copy the inner class available in ExpandableList1 for adapter and I launch it into my activity and I also have the problem see on photo

I am forced to manage density into my adapters in order to adjust the padding?

Android :: ChoiceMode Compatible With ExpandableListView?

May 12, 2010

Is it possible to make a multiple choice list with android:choiceMode="multipleChoice" or setChoiceMode(ListView.CHOICE_MODE_MULTIPLE) on an ExpandableListView? I am able to do this with CheckBoxes on a plain ListView, but it doesn't seem to be working with ExpandableListView. In the latter, clicking the list item (either parent or child) does not affect the checkbox as it does in the former.

I have noticed that it is possible to click exactly on the checkbox to make it toggle, but this is a very small target.

Android :: Disable Collapsing Of ExpandableListView

Aug 11, 2010

The default behavior of ExpandableListView is to collapse a group when its header is clicked. Is it possible to prevent this from happening?

I've tried: Setting OnTouchListener on the list. This interferes with scrolling. Setting an OnGroupClickListener on the list (in onCreate()). This works for all clicks after the first.

Why might the OnGroupClickListener miss the first click?

Android :: Implement An Activity That Uses ExpandableListView

Sep 3, 2010

Im trying to implement an activity that uses ExpandableListView and I have gotten so far but now I have found some strange behavior.

My activity is meant to record food intake as specified by the user. they have a choice of menus (breakfast, lunch and dinner - the outer group) which expand to show their contents.
when a user clicks on an inner menu item a dialog appears asking them for the qty. once they enter a qty and dismiss the dialog the text on the menu item changes to reflect the quantity of that item that has been consumed

The above image shows the list in a closed state.

Below is the list after I have opened the lunch menu and clicked on 'Potato Chips' and indicating a Quantity of 1. As you can see the 'Potato' itemtext has now been changed to reflect the Qty of 1.

The strange part happens now. if I click on 'Lunch' and close the list and then click on it again re-opening it, the 'Qty X 1' text has jumped to another item (Milk)

Each time I open and close the list it jumps back and forth between the two items. Also if I open up other items, such as breakfast, I find that they too have now gotten items with 'Qty X 1' even though I havent clicked them.

The bits of code that are relevant are as such:

The XML for a child element:


The code thats triggered on clicking a child element:


The above code opens a dialog, accepts a value for quantity, appends the list element to reflect this, also saves to database and sets a textview with the selected item and quantity.

Android :: Setting Focus Programatically In ExpandableListView

Aug 28, 2010

I have subclassed ExpandableListActivity to create an activity that presents a simple tree view of the 'world at large' and allows the user to select one for further use by the app. I am having trouble setting focus programatically. One thing that baffles me is that I can use the D-pad to set focus on any of the child or group items in my ExpandableListView, but inside my onChildClick() callback, isFocusable() returns false. If I can set focus with the D-pad, how can isFocusable() return false?

My goal is to avoid having the user have to touch individual ExpandableListView entries to select them and to provide a couple of buttons to move the focus up and down inside the list. I want selection to be easy for folks with no D-pad or with a phone that only presents the D-pad when in landscape mode (e.g. Droid) .

Is there some way I can programatically inject D-pad key clicks into my app input event stream?

Android :: Expandablelistview Won't Work With Context Menus / Why Is So?

Oct 3, 2010

My app used to use a standard ListView, and registerForContextMenu(getListView()) and everything worked just fine.

I needed to change my app to accommodate nested lists so I replaced the ListView with ExpandableListView. I changed the Activity to ExpandableListActivity. I also changed my adapter to a tree adapter and implemented a custom view class to populate the list with (based on a FrameLayout view).

Suddenly my context menus stopped working and I can't figure out why. I can't long click on any of my list items and I'm completely stuck on where to start looking.
