下面是一个在Android ListView中实现多选的例子代码：

XML布局资源文件
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout android:id="@+id/LinearLayout01"
    android:layout_width="fill_parent" android:layout_height="fill_parent"
    xmlns:android="http://schemas.android.com/apk/res/android">
    <ListView android:id="@+id/ListView01" android:layout_height="wrap_content"
    android:layout_width="fill_parent">
    </ListView>
</LinearLayout>

在Activity中绑定列表并显示：
public class ListViewMultipleChoiceExample extends Activity {
    private ListView lView;
    private String lv_items[] = { "Android", "iPhone", "BlackBerry",
"AndroidPeople", "J2ME", "Listview", "ArrayAdapter", "ListItem",
"Us", "UK", "India" };

    @Override
    public void onCreate(Bundle icicle) {
       super.onCreate(icicle);
       setContentView(R.layout.main);
       lView = (ListView) findViewById(R.id.ListView01);
       // Set option as Multiple Choice. So that user can able to select more the one option from list
       lView.setAdapter(new ArrayAdapter<String>(this,
       android.R.layout.simple_list_item_multiple_choice, lv_items));
       lView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    }
}

效果界面如下：

获取选中的列表项操作：
lView.setOnItemClickListener(new OnItemClickListener() {
    public void onItemClick(AdapterView arg0, View arg1, int arg2,long arg3)
    {
        List list = new ArrayList();
        SparseBooleanArray a = lView.getCheckedItemPositions();
        for(int i = 0; i < lv_items.length ; i++)
        {
            if (a.valueAt(i))
            {
                Long val = lView.getAdapter().getItemId(a.keyAt(i));
                Log.v(TAG, "index=" + val.toString());
                list.add(lView.getAdapter().getItemId((a.keyAt(i))));
            }
        }
    }
});
