适配器：

public class CrazyAdapter extends BaseAdapter {    private Context mContext;    private List<String> mList;    public CrazyAdapter(Context mContext, List<String> mList) {        this.mContext = mContext;        this.mList = mList;    }    @Override    public int getCount() {        return mList.size();    }    @Override    public Object getItem(int position) {        return null;    }    @Override    public long getItemId(int position) {        return 0;    }    @Override    public View getView(int position, View convertView, ViewGroup parent) {        ViewHolder holder = null;        if (convertView == null) {            convertView = LayoutInflater.from(mContext).inflate(R.layout.item_list, null);            holder = new ViewHolder();            holder.view = (TextView) convertView.findViewById(R.id.tv_city);            holder.box = (CheckBox) convertView.findViewById(R.id.rb_view);            convertView.setTag(holder);        } else {            holder = (ViewHolder) convertView.getTag();        }        holder.view.setText(mList.get(position));        holder.box.setChecked(((ListView) parent).isItemChecked(position));        return convertView;    }    public final class ViewHolder {        private TextView view;        private CheckBox box;    }}

页面代码：

public class ListViewActivity extends Activity {    private ListView mListView;    private List<String> mList;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_list);        mListView = (ListView)findViewById(R.id.ls_view);        String[] mStrs = {"芥川龙之介", "三岛由纪夫", "川端康成", "村上春树", "东野圭吾", "张爱玲", "金庸", "钱钟书", "老舍", "梁实秋", "亨利米勒", "海明威", "菲兹杰拉德", "凯鲁亚克", "杰克伦敦", "小仲马", "杜拉斯", "福楼拜", "雨果", "巴尔扎克", "莎士比亚", "劳伦斯", "毛姆", "柯南道尔", "笛福"};        mList = Arrays.asList(mStrs);        final CrazyAdapter mAdapter = new CrazyAdapter(this, mList);        mListView.setAdapter(mAdapter);        mListView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);        mListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {                mAdapter.notifyDataSetChanged();            }        });    }}
