I could not figure out how to implement two basic functionalities with the expandable lists: 1. The onClick for the child 2. Using linear layout for the children, so that I can have multiple clickable items in same row under the parent item
Can somebody help me with some sample code for the above?
How to add image in expandable List in parent in android ?
If possible how to customize the child in expandable list?
I am looking to find out how to assign an image to a imageview in each child of an expandable list.
If anyone has any information or links to find out how to do this. code...
is what my adapter looks like at the moment, I have very little experience in customising adapters so I do not know where to start.
1) I have made an customizable expandable List .
2) Where I can customize the child.
3) But in parent(Group ID) I want to change the default icon of the parent.which look like(>).
I am using a simple expandable list that is populated by two arrays ( group array for the groups and a multi dimensional children array for the child). The arrays are built dynamically in the program and some group items have more children than others. So I end up defining the highest number as the array size for the multidimensional child array. After populating the child array, some positions are left null, as there are no values for those group items (explained above). When I associate this with the expandable list adapter, the getChildView method throws a nullpointer exception when it comes across a position in child array that does noto have value. I have two questions:
1. Can I make the base adapter skip the shildview method if the value in that child is null? The current implementation of getchildView method has to return a view and even if I suppress the nullpointer exception, it adds a blank element in the child position in the list.
2. Is there a better way of associated multidimensional arrays that are populated at run time? The current set of examples only use hardcoded string array values. Even the cursor adapters examples use very basic setup.
I 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 RelatedI'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 2 Replies View RelatedI have ListView, where each row contains two edittext boxes. I'd like on list item selected(using Dpad) place focus on first edittext box. I tried the following code, but it does not work: ListView list = (ListView) findViewById(R.id.list); OnItemClickListener click_listener = new OnItemClickListener() {public void onItemClick(AdapterView<?> parent, View view, int position, long id){EditText box1= (EditText ) view.findViewById(R.id.box1); box1.requestFocus(); return ;} list.setOnItemClickListener(click_listener);}
View 2 Replies View RelatedI have a list view which contains different numbers and i have a button below with the name "Call". The expected spec is to change the button background to blue, only if user clicks on list item, and if user clicks on some other views, i need to change the button background to white.
My work around for this issue:
I have set onfocusChangeListener() for the list live, but onFocusChanged() is getting called if next view gets the focus.
Expected result:
1) Background of the button should change to blue if user clicks on list child item.
2) Background of the button should change to white if user clicks on other views.

View 1 Replies View RelatedI have a list where i basically need a hierarchy of items. Any children of an item would be padded slightly, as to easily distinguish their parent item. How could this be achieved? Note that i could, if needed, make each parent show no children, and then when the parent is clicked, a new list containing all of it's children is loaded. This however requires more clicking to display information than i would prefer. Also, the items themselves will contain graphics and whatnot (to show a drag'n'drop button, etc), so it would be best if it visually appeared as if the item itself had a margin, rather than the contents of the item being padded.
