在自定义控件里，怎么删除调用控件的Activity

class MySpinnerDropDownItems extends PopupWindow {
   class MyListViewOnItemClickedListener implements                                AdapterView.OnItemClickListener {
/**
         * listView的点击事件
         * 
 */
                        @Override
                        public void onItemClick(AdapterView<?> parent, View view,
                                        int position, long id) {
   
                                        Intent intent1 = new Intent(context, Activity_Setting.class);
                                        context.startActivity(intent1);

                                //context..finish(); 一样没有finish()方法
                                //this.finish();没有finish()方法
                        }
                }


}
