How do I delete an item from my custom base adapter?

Question

I am extending BaseAdapter to make a custom listview row. I have context menu that opens everytime a user holds on the row and prompts if he wants to delete it. However how

Answer 1

You should add a Listener on your adapter to handle the delete event.

public YourAdapter(Context context, List rows, View.OnClickListener deleteListener) 
{ ... }

And on your getView() method set the listener

yourBtn.setOnClickListener(this.deleteListener);

You can add a value on the btn tag to identifiy the current row :

yourBtn.setTag(position);

Finally, on your Activity, your listener will fire with the current position in tag. You can then use the previous answer to update your adapter and refresh your listview.
