I have a ListView with checkboxes in it.
When I click on a element of the ListView, it does not check/uncheck the checkbox. I want to toggle the checkbox if the user clicks on the checkbox or on the listview.
How can I do that ?
Thank you
Listen for the click event and adjust the state of the CheckBox. The onClick gives you the View that was clicked so you should be able to get the CheckBox easily.
In order to get the click listener of CheckBox in each row of list view, you can add the setOnCheckedChangeListener of checkbox in getView() method of your custom adapter.

I got a listView with dynamically created items. Each item has a checkbox which can be checked/unchecked. When the checkbox is pressed this function is called:
public void updateClientList(View v) {
}
Now I want to change the specific item in my arraylist which is the base of the listview. But how do I know which checkbox was checked?
How can I do that? Thanks for your help!
If you only have a checkbox, you can use the OnItemClick listener that gives you position besides the view, but with this solution you have to update the checkbox manually so it doesnt consume the item click.
Another way is to use setTag(position) on the views you supply when binding.
You should consider moving on to RecyclerView.

Im having a listview with items in a custom relativelayout which implements Checkable. It contains a checkbox which gets checked/uncheked via the checkable interface.
setFocusable is set to false for the Checkbox, so that I can use onItemClicked for the listview.
Now when an item is clicked the checkbox is also selected. I am getting crazy about this.
In the getView Method for my Adapter I assign an onCheckChangeListener to the checkbox.
This listener is called everytime a listitem is clicked and checks the Checkbox.
I saw questions how to select a checkable listitem onitemclick, and im getting this behaviour by default....
The Problem with this behaviour is:
The checkbox should get checked by clicking the checkbox not clicking the listitem. I start an Actionmode for the current visible Fragment when a checkbox is clicked, and i replace the current fragment when a listitem is clicked. BOTH is happening right now and that means, wrong Actionmode for wrong fragment and force close on backpress...

I think you have to make all other item in custom listview to setFocusable="false"
I have a ListView containing a checkbox, an imageview, two textviews and a button. The problem is after adding the checkbox and the button the onitemclick event of the ListView is not responding. Will anybody suggest a work around for the problem?
You can set both android:focusable and android:focusableInTouchMode attributes of checkbox to false and onItemClick of the list will be called. But you'll have to call CheckBox#toggle() yourself in onItemClick.
Add an onlick listner to the view. or the checkbox and handle it manually.
When you use checkbox in your listview then it consumes your click action and your check action will be performed.
You can put click listener over textview, imageview or button. you also need to handle checkbox.
I've a listview where each listitem has a checkbox. When I click list item, OnItemClick is called but checkbox is also clicked, that's annoying coz checbox onclick actions are triggered.
Edit:
how can I prevent checkbox from being clicked when row Item is clicked?
UPD:
Try to add to root view of the listitem layout this attribute android:descendantFocusability="blocksDescendants".
This should work
In the Adapter for the ListView, I return a LinearLayout, in which I add a Checkbox, a ImageView and a TextView. This basically constructs a ListView, in which each item contains a Checkbox, a ImageView and a TextView. However the strange thing is that if I don’t add the Checkbox, then ListView receives onItemClick event correctly, as long as I add the Checkbox, onItemClick of the ListView never gets fired again, as if the Checkbox eats all the OnClick event passed to ListView.
Any ideas how can I solve this? I want the user to be able to check/uncheck the Checkboxes and at the same time be able to click on these ListView items as well if they click on area for the ListView item other than the checkbox.
Set all items focusable="false"
