How to use the onClickListener method of a button in a ListView

I have a custom ListViewone that contains Button. The function of this button is the “Delete” button. Whenever the user clicks this button, the current line will be deleted.

  • How can i do this?
  • How to set onClickListenerfor this button?
  • How can I catch the id of the row on which this button is enabled?

Thanks in advance.
