Remove view from MergeAdapter

Is it possible to remov开发者_开发问答e view or adapter from MergeAdapter somehow? I'd try to extend it and remove the view from pieces but it's private. Or maybe there's an alternative solution to show/hide view in this adapter? I tried to set its layout_height to zero and visibility to View.GONE, but it still shows the empty list item. Thanks in advance.

To remove a view or an adapter from MergeAdapter use the following methods:

setActive() on your mergeAdapter Instance.

For Example : To remove a Textview (mytextView) from a MergeAdapter(merAdapter) use:

merAdapter.setActive(mytextViiew,false);

And to enable it again(to make it visible) use:

merAdapter.setActive(mytextViiew,true);

Refer the MergeAdapter documentation for details:

Not presently, sorry. It shouldn't be too hard to add (remove it from the collection and call notifyDataSetChanged() to update the AdapterView) if you wanted to take a shot at it. Contributions are welcome! :-)

your MergeAdapter should be having method called getCount().. if i have understood you right, returning zero from there may solve your problem..

Expanding on Mark Murphy's answer, I think this is as simple as adding this method to MergeAdapter:

public void removeAdapter(ListAdapter la) {
    pieces.remove(la);
  }

remove() takes an object and will do all of the necessary testing & removal for you, if that object is contained in the pieces list. You could make this return a bool or something for your own purposes, but I had no such need.

Then just call something like:

int view_to_remove = *AN_INT*
adapter.removeAdapter(listAdapter.getAdapter(view_to_remove));
adapter.notifyDataSetChanged();
