Deleting item from listview behaving strange

Question

I have a listview that extends base adapter. There is a delete button on every list item. When the delete button is clicked then the list item should be deleted. But when I try to do so listview behaves strangely. The delete button is causing the main problem. Sometimes the list is becoming double and sometimes app is crashing. I am trying to add a delete button to the item of the listview. When someone clicks on the button then the list item will be deleted and it will delete the item also from firebase.

I am trying to achieve this.

Sorry for my bad English. Advance thanks for your help.
