This answer may help you.

Use code to set onLongClickListener on Gallery object

gal.setOnLongClickListener(new OnLongClickListener() 
{

    @Override
    public boolean onLongClick(View v) 
    {
        // Remove element from array and call adapter.notifysetdatachanged() to update
        // Gallery

        return false;
    }
});
