Android: Context menu callback position off by one when ListView contains a header

I have a ListView with a header, set using ListView.addHeader(...) It appears to work just fine except when trying to create the context menu.

When the user long-presses a row, the position in the onCreateContextMenu callback seems to be off by one. When the user long-presses the header, the position reported is 0 (I wouldn't expect a callback), when the user long-presses the first row, the position reported is 1 instead of 0 and so on.

The same code works as expected without a header.

I know that internally Android just creates a new Adapter around mine when I set a header, but I would assume they handle adjusting the position before invoking callbacks.

Is what I'm seeing expected behavior? Am I doing something wrong, perhaps?

Here's how I fetch the position:

public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) menuInfo;
    int position = info.position;

    // this is my workaround, but I'm afraid it's going to bite me i开发者_运维百科n
    // the ass if/when GOOG fixes this
    if( this.hasHeader() && position > 0 ) position--;

I know that internally Android just creates a new Adapter around mine when I set a header, but I would assume they handle adjusting the position before invoking callbacks.

I doubt it. I have not tried this specific behavior, but having written wrapping adapters myself, it's not a readily solvable problem.

Simply put, the context menu stuff does not involve the Adapter at all, only the AdapterView. Hence, there is no chance for a wrapping Adapter to either consume menu events or to adjust position values.

I suspect that you will simply need to subtract 1 and ignore the header row yourself.
