I made a listview from db and I added onitemclicklistener. When I click on the item it will take me to the next activity and show full detail of the item. I also added a checkbox on the listview which checks the item. The problem is that when I click on the checkbox it wont work, but when I click on the item, it starts the next activity and after it, when I go back to the listview and try again to click on the checkbox, then this item checkbox works and the other one doesn't work. Also when I select a second item from the listview and go back then the checkbox works. Checkbox only works on that item with at least one time click. Does someone have an idea of what could be causing this problem? Here's my Java:
