SQLite Database does't update listview item and inserts new instead

Question

When item of listview is clicked, it gets opened in another activity which has edittext. After editing an item, when I save it, item does not get updat

Answer 1

I think there's problem with your adapter. There are 2 possible issues.

1. Data of adapter are not updated. You're saying opposite, new value is added to ListView. Are you really sure?
2. You haven't called your adapter's method notifyDataSetChanged() after you've changed values.
