Android之记录ListView的checkbox选择位置问题

直接上代码了：

<CheckBox         android:id="@+id/checkbox" android:focusable="false" // 必须有 android:clickable="false" // 必须有        android:layout_marginLeft="20dp"        android:layout_width="wrap_content"        android:layout_height="wrap_content"/>

public class ListViewCheckBoxActivity extends Activity {    private ListView listview;        @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                listview = (ListView) findViewById(R.id.listview);        MyAdapter adapter=new MyAdapter(this);            listview.setAdapter(adapter);            listview.setItemsCanFocus(false);            listview.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);            listview.setOnItemClickListener(new OnItemClickListener(){                @Override            public void onItemClick(AdapterView<?> parent, View view,                    int position, long id) {                // TODO Auto-generated method stub                System.out.println("aa");                ViewHolder vHollder = (ViewHolder) view.getTag();                    //在每次获取点击的item时将对于的checkbox状态改变，同时修改map的值。                    vHollder.cBox.setChecked(true);                boolean check = vHollder.cBox.isChecked();                MyAdapter.isSelected.put(position, check);             }            });      }}
