嗨,我有一个使用visibility = gone atribute隐藏的微调器.我使用spinner.performclick()调用微调器列表,这个工作正常,除了在微调器列表中选择一个项目时,我的onselect监听器永远不会被调用.请帮忙:)

            c.close();
            areYouSureDialog("Are You Sure?", "Are you sure you want to delete the catagory " +'"'

                    + newCatagoryName + '"' + " ?",
                    catagoryIcon, catagoryName,newCatagoryName, DELETE_CATAGORY_MOVE, catagoryId);
        }

        @Override
