If I have a fragment containing a ListView where each row is a series of clickable elements (say, 3 buttons) filling all available space on the row, can I possibly have a long click callback for the entire row?
I want the user to be able to click on any of the three elements with a quick click but the long click should select the entire row/entry.
I have tried hooking up the ListView with the setOnItemLongClickListener while setting android:longClickable on the individual elements in the layout, but I never see the callback get hit for the long press.
Is this feasible? Do I need to have each element listen for the long click and push it back to the ListView somehow?
Since these three elements(Button) filling up entire space of the , it is difficult to set long click listener for that row...
so good idea is set one same long click listener for these elements rather than row, if they don't have any long click events..
thank you
Put longclicklistener on list view and when that is performed some boolean make true and in your 3elements clicklisteners check if it is false than do other commands.

I have studied a number of answers to similar questions but none work in this particular instance (which isn't covered anywhere else).
I have a ListView containing ListItems with a number of TextViews on each.
When I do a short click on any ListItem I am expanding that item to show more information (by implementing an AdapterView.OnItemClickListener).
One of the TextViews has android:longClickable="true" set. This is so that I can run another action when that particular TextView is long clicked (I achieved this by implementing AdapterView.OnItemLongClickListener and checking for the particular TextView id)
I have set android:clickable="false" for that TextView
My issue is that now when I do a short click anywhere on the ListItem the item expands as expected - EXCEPT when the short click is on that particular TextView, in which case nothing happens.
So the short click is being consumed by something even though I have set clickable to false?
Have I missed something obvious? If I set the android:longClickable="false" on that TextView then the expansion works fine again.
It seemed the event is interrupted by the long click listener.
Try to check the return value of the "onItemLongClickListener", it's a boolean type, which will decide the event is handled or not.
Good luck!
I'm building an ExpandableListView in which there are groups of radio buttons.
Currently, I am able to handle the click event on each radio button and select the corresponding one and deselect the others. But there is just one more thing needed to make it perfect. That is displaying the value of the selected checkbox in the group view so the user can see what is selected without expanding it.
For that purpose, I have a TextView in the group view. Is it possible to update that TextView when a checkbox is selected in the child view?
Here is a screenshot of what I have right now:
Basically what I want to accomplish is to make it write the value of the selected checkbox instead of "Regular".
Thanks.
in your example, it seems perfectly reasonable to save a reference to your TextView inside a member variable when it is created. you can then easily update its value by calling setText() on it from within your checkbox's click handler.
it is neither necessary nor desirable to call notifyDataSetChanged().
I have used a button in all list items of a listview. I lost the list item click when i added a clickable componenet is list items of the list view. Now i need to add a button in listitems in of the listview and i added it. I need to have click event for both list items and also the buttons. How can i make is possible.
Please share.
Thanks in advance.
You'll have to attach click listeners to the internal views. Try to create a listener for each ViewHolder and recycle them just like you do for the views passed in to getView(). Note that you'll also have to attach a long click listener or explicitly disable long clicks on the new clickable subview or you will lose the context menu on the list item. Another thing to think about is how you intend to handle d-pad navigation with these sub-views.
My ListView's row has one Button. Now i want to set click event to both row and button. But as i know ListView loose its onItemClick property if we set it's child click event. So please guide me a way to doing both at once
If you are using Buttons inside each list item, then set the click listener for the buttons on not on the list item.
Button.setOnClickListener(View.OnClickListener)
The list item clicks should go ignored and the buttons click listeners should do what you want.
You have to use ListView.setOnItemClickListener(OnItemClickListener). See the tutorial.
In OnItemClickListener.onItemClick() you're provided with the position of the item.
I don't understand why you don't want to use ListView.setOnItemClickListener(OnItemClickListener) ?
Because it react instantly to a touch event. Isn't what you want?
I have just started my career as an android programmer, and am currently relying heavily on the sample code and api examples. I have been working with this api example, to produce an expandable list of items (note this example does not use the ExpadableListView).
In playing with the example, I tried to add another widget that would become visible and be gone at the same time as the text (mDialogue in the sample code). This works well with another TextView, but as soon as I tried to add a button widget, it stopped working. The list would expand on first click, showing my hidden TextView and Button, but it will not disappear on further clicks. The button is however, clickable, and I was able to set up an onClick listener to change the button text back and forth.
I'm starting to wonder, is it just not possible to have a clickable item inside a clickable list item? Or is there some kind of work around? Would it solve my problem if I used ExpandableListView?
You have two options of how to handle focus within a ListView controlled by ListView#setItemsCanFocus(boolean). If you want individual Views within a list item to focus so that the user can interact with them individually instead of with the list item as a whole, call it passing true. false is the default behavior.
The default behavior where ListView manages item focus and clicks is basically a shortcut/optimization for the common case where the whole item acts as a single unit from an interaction standpoint, but its layout may be complex. When you tell ListView that its items can focus it disables this special behavior and you should use the more traditional mechanisms of handling events on the Views within the list items. (Listeners, overridden on* methods, etc.)
But why do your list items stop taking clicks when your ListView isn't set up for focusable items? ListView will only generate item click events if the list item view returns false from View#hasFocusable(). This means no children of the list item can be focusable if you want to receive item click events for it. As soon as your button becomes visible, the list item has a focusable child and will no longer receive list item click events.
