ListView checkbox_Android之记录ListView的checkbox选择位置

多的不说、上代码

<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);
