How to get the id or position of an element on click?

Question

Android

I am using RecyclerView + SQLite to store and display items. When clicking, you need to pass the ID (of this element from the database) through the intent to another activity.
There is a method that implements getting data from the database (_id and product name).
If you specify the code below, then when you click on an element in another activity, I get numbers from 3 to 9 (this is clearly not the ID of the selected element).

descriptionIntent.putExtra("drugID", mCursor.getString(mCursor.getColumnIndex("_id")));

If you specify this code, then I get null

descriptionIntent.putExtra("drugID", mCursor.getPosition());

How do you get the id of an element?

Answer 1

Write down the id at the stage of obtaining from the source. For example map to data-classes. Cursor at a particular moment always looks at one particular line, so you get not the IDs of the elements you clicked on, but the ID from the current cursor position.
