There could be several reasons why the last element is being removed instead of the intended element when deleting an element from a listView:
Incorrect indexing: The wrong index may be used to remove the item from the list. This can occur due to a variety of reasons, such as off-by-one errors or confusion in the indexing order.
Data source not updated: The data source used to populate the listView may not have been updated after the deletion. This can result in the index values within the listView being disordered and may cause unexpected deletions.
View recycling: The view recycling feature of a listView can cause the incorrect element to be deleted. This is because, when a view is recycled, its position data is retained, and if its position data is not correctly synchronized with the underlying data source, it can lead to the wrong element being selected for deletion.
Duplicated items: Duplicated items in the listView can cause confusion in identifying the intended element to be deleted. In such cases, the last element, which is the most recent duplicate, may be deleted instead of the intended element.
To fix this issue, it is essential to ensure that the correct indexing is used, and the underlying data source is updated after the deletion. Additionally, the view recycling feature should be handled correctly, and duplicated items should be removed before deleting elements from the listView.
