android 如何获得多选框选中的值？

[清澈@Cherry]

如何获得多选框选中的值？使用了listview，每个列表项表框一个显示的textview和一个checkbox，请问如何取得值呢？我使用了网上这位仁兄的办法，没有起作用，代码如下：

// 去掉相同的商品
		List<Instrument> instList = APIDoc.getSystemDocCaptain()
				.getInstrumentList();
		listems = new ArrayList<Map<String, Object>>();
		for (Instrument instrument : instList) {
			Map<String, Object> listem = new HashMap<String, Object>();
			listem.put("instrument", instrument.getInstrument());
			listems.add(listem);
		}

		SimpleAdapter simplead = new SimpleAdapter(getApplicationContext(),
				listems, R.layout.activity_systeminstrument_item,
				new String[] { "instrument" },
				new int[] { R.id.addsysteminstrument });

		instrumentList = (ListView) findViewById(R.id.systeminstrumentlistview);
		instrumentList.setAdapter(simplead);
		// final ListView listView = getListView();
		// listView.setItemsCanFocus(false);
		instrumentList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);

		instrumentList.setOnItemClickListener(new OnItemClickListener() {

			@Override
			public void onItemClick(AdapterView<?> parent, View view,
					int position, long id) {
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");
				System.out.println("你点击了" + "************");

				List list = new ArrayList();
				SparseBooleanArray a = instrumentList.getCheckedItemPositions();
				for (int i = 0; i < listems.size(); i++) {
					if (a.valueAt(i)) {
						Long val = instrumentList.getAdapter().getItemId(
								a.keyAt(i));
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						System.out.println(val + "************");
						list.add(instrumentList.getAdapter().getItemId(
								(a.keyAt(i))));

					}
				}

				for (Iterator i = list.iterator(); i.hasNext();) {
					System.out.println(i.next());
				}

			}
		});

ListView.setOnItemClickListener()，重载这个监听器中的onItemClick()方法，里面会获得一个position变量，应该就是你想要的值

checkbox不是有事件监听吗
