1 创建适配器

data = service.getAllDataStringArray();
ArrayAdapter<String> charaAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_checked, data);
eventCharaList.setAdapter(charaAdapter);
eventCharaList.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
eventCharaList.refreshDrawableState();// TODO 刷新listview，否则，获取checkedItem的时候会受上次打开listview的选择影响

2 获得选择的选项

	StringBuilder sb = new StringBuilder();
	SparseBooleanArray positions = eventCharaList.getCheckedItemPositions();
	int size = positions.size();
	for(int index=0;index<size;index++){
			sb.append(data[positions.keyAt(index)]+",");
	}
							
        Toast.makeText(getActivity(), String.valueOf(eventCharaList.getCheckedItemCount())+";"+sb, 0).show();
