Android - ลบแบบ Row Database Android ไม่ได้อ่ะค่ะ ช่วยแนะนำหน่อยนะคะ

    public void onCreateContextMenu(ContextMenu menu, View v,
    		ContextMenuInfo menuInfo) {
    	//if (v.getId()==R.id.list) {
    	    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo)menuInfo;
    		menu.setHeaderTitle("Command for : " + MebmerList.get(info.position).get("Name").toString());
    		String[] menuItems = getResources().getStringArray(R.array.CmdMenu); 
    		for (int i = 0; i<menuItems.length; i++) {
    			menu.add(Menu.NONE, i, i, menuItems[i]);
			}
    	//}
    }
