ListView里面嵌套CheckBox

布局文件

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >
    <TextView
        android:id="@+id/tv"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical" />

    <LinearLayout
        android:id="@+id/line"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:layout_below="@+id/tv"
        android:orientation="horizontal" >

        <Button
            android:id="@+id/bt_selectall"
            android:layout_width="80dp"
            android:layout_height="fill_parent"
            android:text="全选" />
        <Button
            android:id="@+id/bt_cancleselectall"
            android:layout_width="80dp"
            android:layout_height="fill_parent"
            android:text="反选" />

        <Button
            android:id="@+id/bt_deselectall"
            android:layout_width="80dp"
            android:layout_height="fill_parent"
            android:text="取消选择" />
    </LinearLayout>
    <ListView
        android:id="@+id/lv"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@+id/line" />

</RelativeLayout>

二,对应的activity

public class Ex_checkboxActivity extends Activity {
    private ListView lv;
    private MyAdapter mAdapter;
    private ArrayList<String> list;
    private Button bt_selectall;
    private Button bt_cancel;
    private Button bt_deselectall;
    private int checkNum; // 记录选中的条目数量
    private TextView tv_show;// 用于显示选中的条目数量

    /** Called when the activity is first created. */

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        /* 实例化各个控件 */
        lv = (ListView) findViewById(R.id.lv);
        bt_selectall = (Button) findViewById(R.id.bt_selectall);
        bt_cancel = (Button) findViewById(R.id.bt_cancleselectall);
        bt_deselectall = (Button) findViewById(R.id.bt_deselectall);
        tv_show = (TextView) findViewById(R.id.tv);
        list = new ArrayList<String>();
        // 为Adapter准备数据
        initDate();    //加载15 条数据
        // 实例化自定义的MyAdapter
        mAdapter = new MyAdapter(list, this);
        // 绑定Adapter
        lv.setAdapter(mAdapter);

        // 全选按钮的回调接口
        bt_selectall.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // 遍历list的长度，将MyAdapter中的map值全部设为true
                for (int i = 0; i < list.size(); i++) {
                    MyAdapter.getIsSelected().put(i, true);
                }
                // 数量设为list的长度
                checkNum = list.size();
                // 刷新listview和TextView的显示
                dataChanged();
            }
        });

        // 反选按钮的回调接口
        bt_cancel.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // 遍历list的长度，将已选的设为未选，未选的设为已选
                for (int i = 0; i < list.size(); i++) {
                    if (MyAdapter.getIsSelected().get(i)) {
                        MyAdapter.getIsSelected().put(i, false);
                        checkNum--;
                    } else {
                        MyAdapter.getIsSelected().put(i, true);
                        checkNum++;
                    }
                }
                // 刷新listview和TextView的显示
                dataChanged();
            }
        });

        // 取消按钮的回调接口
        bt_deselectall.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                // 遍历list的长度，将已选的按钮设为未选
                for (int i = 0; i < list.size(); i++) {
                    if (MyAdapter.getIsSelected().get(i)) {
                        MyAdapter.getIsSelected().put(i, false);
                        checkNum--;// 数量减1
                    }
                }
                // 刷新listview和TextView的显示
                dataChanged();   //刷新adapter
            }
        });
        // 绑定listView的监听器
        lv.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position,
                    long id) {
                // 取得ViewHolder对象，这样就省去了通过层层的findViewById去实例化我们需要的cb实例的步骤
                ViewHolder holder = (ViewHolder) view.getTag();
                // 改变CheckBox的状态
                holder.cb.toggle();
                // 将CheckBox的选中状况记录下来
                MyAdapter.getIsSelected().put(position, holder.cb.isChecked());
                // 调整选定条目
                if (holder.cb.isChecked() == true) {
                    checkNum++;
                } else {
                    checkNum--;
                }
                // 用TextView显示
                tv_show.setText("已选中" + checkNum + "项");
            }
        });
    }
    // 初始化数据
    private void initDate() {
        for (int i = 0; i < 15; i++) {
            list.add("data" + " " + i);
        }
    }
    // 刷新listview和TextView的显示
    private void dataChanged() {
        // 通知listView刷新
        mAdapter.notifyDataSetChanged();
        // TextView显示最新的选中数目
        tv_show.setText("已选中" + checkNum + "项");
    };
}

三,  里面的adapter

public class MyAdapter extends BaseAdapter {
    // 填充数据的list
    private ArrayList<String> list;
    // 用来控制CheckBox的选中状况
    private static HashMap<Integer, Boolean> isSelected;
    // 上下文
    private Context context;
    // 用来导入布局
    private LayoutInflater inflater = null;

    // 构造器
    public MyAdapter(ArrayList<String> list, Context context) {
        this.context = context;
        this.list = list;
        inflater = LayoutInflater.from(context);
        isSelected = new HashMap<Integer, Boolean>();
        // 初始化数据
        initDate();  //都设置为false
    }

    // 初始化isSelected的数据
    private void initDate() {
        for (int i = 0; i < list.size(); i++) {
            getIsSelected().put(i, false);
        }
    }

    @Override
    public int getCount() {
        return list.size();
    }

    @Override
    public Object getItem(int position) {
        return list.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder = null;
        if (convertView == null) {
            // 获得ViewHolder对象
            holder = new ViewHolder();
            // 导入布局并赋值给convertview
            convertView = inflater.inflate(R.layout.listviewitem, null);
            holder.tv = (TextView) convertView.findViewById(R.id.item_tv);
            holder.cb = (CheckBox) convertView.findViewById(R.id.item_cb);
            // 为view设置标签
            convertView.setTag(holder);
        } else {
            // 取出holder
            holder = (ViewHolder) convertView.getTag();
        }
        // 设置list中TextView的显示
        holder.tv.setText(list.get(position));
        // 根据isSelected来设置checkbox的选中状况
        holder.cb.setChecked(getIsSelected().get(position));
        return convertView;
    }

    public static HashMap<Integer, Boolean> getIsSelected() {
        return isSelected;
    }
   //获得map的
    public static void setIsSelected(HashMap<Integer, Boolean> isSelected) {
        MyAdapter.isSelected = isSelected;
    }

    public static class ViewHolder {
        TextView tv;
        CheckBox cb;
    }
}

adapter下的item 的布局文件

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <TextView
        android:id="@+id/item_tv"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_gravity="center_vertical"
        android:layout_weight="1" />

    <CheckBox
        android:id="@+id/item_cb"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:clickable="false"
        android:focusable="false"  // 注意:    这里去除checkbox的焦点
        android:focusableInTouchMode="false"
        android:gravity="center_vertical" />

</LinearLayout>
