Answer 1

listView.setOnItemClickListener(new OnItemClickListener() {  public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {

//view对象 就是你所选的那一栏,下面获取里面的子控件。当然个人还是自己写XML定义一个//ListView，便于处理.
view.findViewById(android.R.id.text1);//应该是TextView类型的
view.findViewById(android.R.id.text2);//应该是TextView类型的

}
});

private ArrayList<String> lists;
ListView listView;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        lists=new ArrayList<String>();
        Cursor c=getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
        startManagingCursor(c);
        if(c!=null){
         c.moveToFirst();
         do{
         lists.add(c.getString(c.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME)));
         }while(c.moveToNext());
        }
        ListAdapter adapter=new SimpleCursorAdapter(this,  
        android.R.layout.simple_list_item_multiple_choice,
        c, new String[]{ContactsContract.Contacts.DISPLAY_NAME,ContactsContract.Contacts.HAS_PHONE_NUMBER},
        new int[]{android.R.id.text1,android.R.id.text2});
        setListAdapter(adapter);
        listView = getListView();
        listView.setItemsCanFocus(false);
        listView.setOnItemClickListener(this);
        listView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
    } @Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
// TODO Auto-generated method stub
SparseBooleanArray a = listView.getCheckedItemPositions();
for(int i = 0; i < lists.size() ; i++)
        {
            if (a.valueAt(i))
            {
                Long val = listView.getAdapter().getItemId(a.keyAt(i));
                Toast.makeText(ShowPeopleList.this, "index="+val.toString()+lists.get(i), Toast.LENGTH_SHORT).show();
            }
        } }
