I have a ListView containing items with one button each and I want to handle user events in this order:
TouchEvent on ListView.
TouchEvent on ListItem.
Click on Button inside ListItem.
How can I do this?
If understand correctly, with a single user click, you want to trigger the event (but not catch it) for each one of those items? You can't. I'd make either the list item or the button the clickable item, handle that, and do all of the logic you need to do in that handler.

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 am trying to implement the listview with swipe to delete and undo in my project. it works fine.code for demo is Here.
But my need is to handle click event for each view, each view have some action to perform.
According to this image, view which one is in middle(data 1, data 2) have a clickListener, when i swipe from right to left by put the finger on lastview(yellow or grey round) it detect the swipe but when i try to swipe from middle Textview (data 1, data 2) it not allow me to swipe from textview(data 1 , data 2).
my need is to start swipe from any where in list row and also handle click of each view (inside row like edittext, Textview and Imageview).
Can anybody help me to come out from this?
all you need is a some research about ViewGroup.onInterceptTouchEvent() method
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.
