Android ListView child View setEnabled() and setClickable() do nothing

I'm doing some AsyncTask work after user clicks an item in my ListView. I'd like to disable the item so it can't be clicked twice. I've simplified the click listener to contain only this method, but it still doesn't do anything for me, the view looks the same and it lets itself be happily clicked again, much to my annoyance.

public void onItemClick(AdapterView<?> parent, View clickedView,
  int position, long id) {
  item = (Episode) parent.getItemAtPosition(position);
  clickedView.setClickable(false);
  clickedView.setEnabled(false);
  clickedView.invalidate();
}

My View for each row is a custom LinearLayout with two TextViews.

So, you may be using a custom adapter too. If you do, override these methods:

public boolean areAllItemsEnabled() {
    return false;
}

public boolean isEnabled(int position) {
    // return false if position == position you want to disable
}

Then, when you receive a click tell the adapter what was the last item clicked and return false on isEnabled for that position. For instance, you can have a method like this in your adapter:

private int mLastClicked;
public void setLastClicked(int lastClicked){
    mLastClicked = lastClicked;
}
