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.

I have a list view which uses a custom adapter in order to show my custom content. Its layout is the following.
CODE:...............
I would like that the listview only showed the view with the ids itemimage and item description, keeping the itemtext hidden.
The idea is to have an onclicklistener on each item of the list, in order to expand that item so it shows the itemtext content. I know I should use Tweening animation in order to expand/collapse each item, but I can't figure out how to do that.
I need to define the structure of ExpandableListView in xml file manually. Is there any guide or example of doing this?

View 1 Replies View RelatedBasically I am trying to recreate the default contact screen when you click on "+" button another row of Phone number added to the list. Right now I have an ImageView as the "+" button and a ListView to contain the list of phone numbers. The problem is that the ListView doesn't expand when I add more item into the list. I could build the same look with LinearLayout but how can I save all those numbers that way? Below is the layout of the item that will be inflate with custom Adapter:
<?xml version="1.0" encoding="utf-8"?> <TableLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content" android:layout_height="60px"
android:stretchColumns="1" android:background="#FFFFFFFF"
android:gravity="center_vertical"> <TableRow>
<Button android:id="@+id/type" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:text="Home" /> <RelativeLayout android:layout_width="fill_parent"
android:layout_height="wrap_content" android:paddingLeft="10dp"
android:paddingRight="10dp" >
<EditText android:id="@+id/value" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:layout_alignParentTop="true"
android:layout_alignParentLeft="true" android:text="" android:hint="Name"
android:lines="1" android:textSize="10pt" android:typeface="sans"
android:textColor="#FF000000" android:gravity="left" /
</RelativeLayout> <ImageView android:id="@+id/del"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:layout_alignParentRight="true" android:layout_alignParentTop="true"
android:paddingRight="14dp" android:src="@android:drawable/ic_delete" />
</TableRow> </TableLayout>
This is the ListView portion.
<ListView android:id="@+id/phoneList" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:background="#FFFFFFFF"
android:scrollbars="none" />
I'm having a little problem with a ListView scrollbar. The scrollbar appears at the side as expected, but how do I get the scrollbar to expand and become controllable in the same way it behaves in the Contact list? Ideally I'd like all the Contacts list functionality for my app - i.e. to allow me to control the scrollbar directly with a finger and to show the first letter of the list elements you're currently scrolled to.

Basically, I have a custom ListView in which each item looks like:
CODE:..........
The ListView in each item is GONE by default and is set to VISIBLE when the button is clicked. Everything seems to work fine with the exception that when the ListView is long enough to scroll, it is just kind of truncated. http://img38.imageshack.us/img38/3269/listviewproblem.png
Is this a problem with the maximum height of an individual list item? Is there a way to force the list item to expand and force the child listview to expand to show all children?
Is 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.

Here replpulateList() method will add to listview items. It doesn't remove/replace all listview items.
I'm using BaseExpandableListAdapter, and there is a drop-down button (looks like an arrow) on the left side for each parent item to indicate that you can expand that item to view child items. The question is: How can I change the properties of that drop-down button such as its position? I basically want to move it a bit lower in each parent item.

View 1 Replies View RelatedI am trying to compose a list with some items expandable and some single items. I wish to have it so that when either a single item or expandable list child is clicked, I can call an intent based on the text of the item.I suppose expandable lists would work, but is there a way to set items in an expandable list so that they don't have the expandable list icon? Should I use something other than a string array?What is the best way to do this?

View 1 Replies View RelatedIs there a way to expand the VM limit in Android 2.0 on an actual device? Using java.lang.Runtime.maxMem() on a Droid reveals a limit of 24MB, and I've written some code that incrementally allocates memory until failure to verify that figure. You can set the VM size in the emulator, but I haven't yet found a way to do that for a connected phone. Is there some type of a properties file on the device itself that can be modified?
