Retrieve _id value without context menu

I am building a custom ListView (card style) and would like to have an edit and delete button on the card. In order to invoke the methods on the correct database rows, I need to know which _id (View) the user selected.
Currently, I am using a context menu which is pretty easy
@Override
public void onCreateContextMenu(ContextMenu menu, View v,
ContextMenuInfo menuInfo) {
super.onCreateContextMenu(menu, v, menuInfo);
AdapterContextMenuInfo info = (AdapterContextMenuInfo) menuInfo;
position = (int) info.id;
MenuInflater m = getMenuInflater();
m.inflate(R.menu.history_popup_menu, menu);
}
@Override
public boolean onContextItemSelected(final MenuItem item) {
switch(item.getItemId()){
case R.id.delete:
...
in this case, I get the id (position) in the onCreateContextMenu
I am wanting to get rid of the context menu now and just have edit and delete on the card itself.
How do I go about retrieving the _id from the database and assign it to a value to be used in my delete/edit method?
This is my method for creating the list
private void addItemsToList(){
Cursor cursor = db.getAllLogs();
Log.d("history.java", "finished Cursor cursor = db.getAllLogs();");
String[] from = {"_id", "date", "gallons", "pricePerGallon", "odometer", "filledOrNot", "comments", "totalSpent"};
int[] to = {deleteVal, R.id.cardDate, R.id.cardGallons, R.id.cardPrice, R.id.cardOdometer, R.id.cardFilledOrNot, R.id.cardComments, R.id.usd};
adapter = new SimpleCursorAdapter(this, R.layout.history_list_item, cursor, from, to, 0);
String filledOrNotVal = String.valueOf(R.id.cardFilledOrNot);
if (filledOrNotVal == "False"){
Log.d("history", "False");
} else {
Log.d("history", "True");
}
listContent.setAdapter(adapter);
}
